String Theory remains the most magical structure we have encountered in theoretical physics and the magic seems directly connected to the particle physics of the real world Ive personally never understood why showing that (unphysical limits of) your quantum theory gives the expected semi-classical result is anything other than a rather weak consistency check on your theory. Can I tell police to wait and call a lawyer when served with a search warrant? Strings 2021 will be held online during the two-week period June 21 July 2, 2021 from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). Our conjecture, which we have developed with Ben-Zvi, Gunningham and Safronov, asserts an equality of dimensions between the G- and G^L-skein modules of a 3-manifold at generic quantization parameter. Title: Bootstrapping AdS/BCFT StringBufferStringBuilder 1. As an application, I will use conformal bootstrap techniques to obtain new rigorous bounds on the first positive Laplacian eigenvalue of hyperbolic orbifolds. Abstract: The D3-D5 and D2-D4 probe-brane systems with nonzero worldvolume flux are holographically dual to N=4 super Yang-Mills and ABJM theory in the presence of half-BPS domain walls. While the community just spread out to other problems. They have obvious applications to atomic physics. Is it possible to create a concave light? Yuji Tachikawa Talks are available for watching every day via Youtube, links are on the main page. From this description, we propose a symmetry for the space of instantons on C^2 by an exceptional super Lie algebra called E(3|6). 4. +1 upvote from me, and I've already used it in a project. We provide new the structure that allows this, whose quantisation turns out to be lead to a multimatrix ensemble. As has been the case for many years, it doesnt look like there will be anything significantly new on the age-old problems of getting fundamental physics out of a string theory. TheAttractor Flow Tree conjecture postulates that the BPS index $\Omega(\gamma,z)$ for given charge $\gamma$and moduli $z$ can be reconstructed from the`attractor indices $\Omega_*(\gamma_i)$ counting BPS states of charge $\gamma_i$ in their respective attractor chamber, by summing over all possible decompositions $\gamma=\sum_i \gamma_i$ and over decorated rooted flow trees. Institutode Matemtica Pura e Aplicada (IMPA), Organizers: Henrique Bursztyn (IMPA), Reimundo Heluani (IMPA), Marcos Jardim (IMECC-UNICAMP), Gonalo Oliveira (UFF). Abstract: We discuss the partition functions of topologically twisted 5d SU(2) supersymmetric Yang-Mills theory on X x S1, where X is a smooth closed four-manifold. August 2-7, 2021: International Congress on Mathematical Physics (ICMP) 2021 (session Quantum Field Theory), Geneva, Switzerland. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. Rio de Janeiro, June 18th, 2021. Inspired by definitions of abstract (finite) groups and algebras and their linear actions, we introduce a framework for these symmetries in field theory. Maxim Kontsevich (IHS) Title: Giant Gravitons in Twisted Holography But, as has also been the case for many years, the conference features many talks that have nothing to do with string theory and may be quite interesting. Albrecht Klemm Abstract: The sphere packing problem is a very natural geometric question and it has a long and exciting history. The key steps in this equivalence is a probabilistic derivation of the DOZZ formula for the structure constants, the spectral analysis of the Hamiltonian of the theory and the proof that the probabilistic construction satisfies certain natural geometrical gluing rules called Segals axioms. I just had a look at that session, and more than anything, felt sorry seeing such eminent physicists giving such vacuous reasons just for the sake of defending a theory they have worked on for a long time. Abstract: Quantum curves can be associated with the singular vectors in the Verma modules over the Virasoro algebra. The qubit example is a bit unfair since in some sense its the quantization of the sphere, although this sphere is not a classical limit of the quantum theory (and sphere isnt a cotangent bundle of some configuration space). As Peter keeps on repeating, the denial of the string community to acknowledge the failure of string theory as a unification theory (which is nothing to be ashamed off: physics is full of beautiful theory that are not correct) is a shame for the physics community. Abstract: I will explain how to explicitly calculate knot homology using the Fukaya category associated to a 2d Landau-Ginsburg theory, which is the equivariant mirror of the Coulomb branch of a 3d $mathcal{N}=4$ theory. Title: A Yang-Mills matrix theory What sort of strategies would a medieval military use against a fantasy giant? Chen-Te Ma (Asia Pacific Center for Theoretical Physics) Hello, Robert A. Wilson Title: The higher dimensional tropical vertex In two dimensions, thesebounds allow us to determine the set of first eigenvalues attained by all hyperbolic orbifolds. I would be eager to read a real formal discussion if first-quantised RNS superstring in euclidean signature is quantum mechanically equivalent (unitary Boguliubov transformation) to original version starting from Minkowski signature. Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory In physical terms, we will discuss a relation between the BPS spectrum of an N=2 4-dimensional field theory and the enumerative geometry of the corresponding Seiberg-Witten integrable system. Strings provided the authors with a way to make relatively small changes to guided notes in algebra 1, algebra 2, precalculus, and AP calculus classes. We provide significant evidence that averaging plays an important role in reproducing. Title: Integrability check for open quantum systems in Krylov Space [Slides] [Video], Lauren Williams (Harvard University) Biogram (in Polish): Maryna Viazovska urodzia si, uczya i studiowaa w Kijowie w Ukrainie. I will describe how to bootstrap these perturbative corrections without computing actual Feynman integralsand present some preliminary results for pure N=1 gauge theory. Blasting is well underway in South Dakota for the $2 billion + LBNF/DUNE facility. Title: Liouville conformal field theory: from the probabilistic construction to the bootstrap construction We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. [Slides] [Video], Brian Williams (University of Edinburgh) This jargon sounds a bit confusing. rotations and translations are typically discretized due to the presence of a lattice)? What video game is Charlie playing in Poker Face S01E07? Can I did this command pattern if I declare the operator how it were a variable? Its very good but he often leaves the reader a lot to figure out. Physically, flow treesprovide a mesoscopic representation of BPS states as nested multi-centered bound states of elementary constituents. Title: On topology change in Poisson-Lie T-duality Strings 2021 started today, program is available here. Moving away from such orbifold points requires generalizing the flow tree formula from the Abelian category of quiver representations to the derived category of the same. The real stuff happens in physics without a press release, book, or blog. Title: A holomorphic approach to fivebranes Due to its interaction, the system density matrix and operators within the system Hilbert space evolve non-unitarily. commutative) spacetime case is well-known to yield the Yang-Mills(-Higgs) theory, namely almost-commutative manifolds, has to be replaced by its fuzzy counterpart already the classical level.

I could go on the whole night, but I believe, as most other string theorists do, there are more urgent or at least doable problems to solve now. Abstract: The problem of quantization of noncommutative spaces (spectral triples) is addressed first in a finite-dimensional, Euclidean setting (thus referred to as random noncommutative geometry, or Dirac ensambles). As a result, he sees the current situation as.

Physics Meets AI, LMU Munich, September 2020. Time permitting, we will discuss a number of related results, such as the cluster structures and Newton-Okounkov bodies determined for the exceptional family in [Spacek-Wang22], and connection to other mirror symmetry statements such as the quantum D-module isomorphism proven for minuscule homogeneous spaces in [Lam-Templier17]. We physically derive (i) a novel Vafa-Witten four-manifold invariant associated with this moduli space, (ii) their relation to Gromov-Witten invariants, (iii) a novel Vafa-Witten Floer homology assigned to three-manifold boundaries, (iv) a novel Vafa-Witten Atiyah-Floer correspondence, (v) a proof and generalization of a conjecture by Abouzaid-Manolescu about the hypercohomology of a perverse sheaf of vanishing cycles, (vi) a Langlands duality of these invariants, Floer homologies and hypercohomology, and (vii) a quantum geometric Langlands correspondence with purely imaginary parameter that specializes to the classical correspondence in the zero-coupling limit, where Higgs bundles feature in (ii), (iv), (vi) and (vii). He notes that to get at non-perturbative string theory we seem to need some more general understanding of quantum theories, going beyond the usual quantization starting with an action, and ends by saying maybe quantum information theory can help. Greg Moore [Slides], Aranya Bhattacharya (IISc, Bangalore) String-Math 2021 conference (IMPA, Rio de Janeiro), [R = Review lecture] ; [D = Discussion session] ; [T = Research talk] ; [P = Public lecture] ; [S = Starting/Summary talks] ; [G = Gong-show talk]. The Ryu-Takayanagi formula then encodes the fractal dimension of the boundary, while the extremal surfaces encode an important part of the geometry of the buildings, showing a new interplay between ideas from holography and geometric group theory. If one knows how to read between the lines, then at this lecture you finally can hear what, in different words, could well be re-phrased as: the search for M-theory using dualities failed. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. This provides an enumerative interpretation of the A-model topological string partition function on non-commutative resolutions of the singular Calabi-Yaus. Title: q-series for so(3) and osp(1|2) The whole tone of the discussion was pretty depressing. Title: Non-Invertible Symmetries and Higher-Categories https://8ecm.si/prizes, Ashoke Sen has computed the logarithmic corrections to the Bekenstein-Hawking entropy of various standard black hole solutions in this paper.
