Summary: The future utility of modern numerical conformal bootstrap relies heavily on accurately predicting the existence of previously unknown non-trivial conformal field theories (CFTs). This study investigates the possibility of predicting such theories when the global symmetry group has a product structure. The results suggest that the large-N antichiral theory lies outside the region of acceptance in the chosen space of scaling dimensions, consistent with its instability.

Summary: In this study, a strong/weak duality between a Heisenberg coset with sl n subregular W-algebra symmetry and a theory with sl(n|1)-structure is examined. Correlator correspondences for a series of generalized duality are derived, as part of a project to realize duality of corner vertex operator algebras proposed by Gaiotto and Rapcak. Another type of duality involving an additional pair of fermions is also examined, which is a natural generalization of the fermionic FZZ-duality.

Summary: In this study, the authors systematically examine 4D N = 2 superconformal field theories constructed via isolated hypersurface singularities in C-4 using type IIB string theory. They show that theories in this class without exactly marginal deformations do not possess 1-form symmetry, which may have origins in gauge groups. Furthermore, it is suggested that general interacting 4D N = 2 SCFTs with Coulomb branch chiral ring generators of dimension less than two also lack 1-form symmetry.

Summary: This paper explores the connection between two-dimensional conformal field theories defined by error-correcting codes and their generalization to quantum error-correcting codes at higher genus. It is proved that the higher-genus partition functions can be expressed as polynomials of higher-weight theta functions, and that the higher-genus modular group acts as simple linear transformations on these polynomials. The study shows that modular invariance at higher genus is more constraining than at genus 1 alone, leading to a drastic reduction in the space of possible code CFTs. The paper also discusses the application of the code polynomial form beyond the study of code CFTs.

Summary: We study the invariant four-point functions with generic multi-cycle fields and twist-2 fields in the D1-D5 CFT at the free orbifold point. By considering the action of the symmetric group, we derive the explicit factorization of these functions and simplify their forms. We also investigate the leading order contribution in the large-N limit by studying the correlators with two double-cycle and two single-cycle fields. Furthermore, we discuss the properties of generic multi-cycle Q-point functions in M-N/S-N orbifolds.

Summary: In this study, the Weak Gravity Conjecture is re-formulated in terms of a particle with non-negative self-binding energy, and the convex charge conjecture is refined and further tested via semiclassical computations for fixed charge sectors of different theories. The leading contribution in the semiclassical computations is found to be sufficient to test convexity, and intriguing cases where models transition from real to complex conformal dimensions are explored. It is discovered that whenever a complex conformal dimension appears, the real part satisfies the convexity property.

Summary: The study focuses on searching for fixed points of 2+1 dimensional N=1 Wess-Zumino models of scalar superfields interacting through a cubic superpotential using the 4-epsilon expansion. Different classifications and analyses of fixed points in cases of N-Phi = 3, 4, and 5 are conducted, with a particular emphasis on irreducible fixed points where scalar superfields form a single irreducible representation of the symmetry group.

Summary: In quantum field theory, orbifolds are obtained by gauging a finite global symmetry, but this does not apply to quantum gravity theories. In string theory, orbifolds involve gauging global symmetries on the world-sheet theory or quotienting isometries. We propose a new formulation of string orbifolds based on the gauge symmetries of a given string model. Through examples, we show how the higher group structure of the parent theory determines the gauge group and twisted sector of the orbifold theory. The dependence of this orbifold procedure on the duality frame is also discussed.

Summary: This study proposes a mesoscopic setup for the Kondo effect that can produce emergent anyons, including Majorana fermions, Fibonacci anyons, and Z3 parafermions, even without perfect channel symmetry. The model is mapped to the multichannel Kondo effect associated with an internal SU(2) symmetry, and the scaling of various observables, including conductance, is predicted using conformal field theory. This work not only provides a platform for robust Kondo-based anyons, but also sheds light on the physics of strongly correlated materials with competing order parameters.

Summary: This paper investigates how error-correcting codes define conformal field theories and extends their applicability. By calculating averaged observables of error-correcting codes, the partition function is obtained and shown to have special properties. The findings contribute to the understanding of the relationship between conformal field theories and error-correcting codes.

Summary: This paper explicitly presents complete sets of independent conserved charges and their nonlinear algebras for rational quantum Calogero systems of type A(1)circle plus A(2), AD(3) and BC3. Intertwining operators are used to include the extra 'odd' charges appearing for integral couplings, and formulas for energy eigenstates are employed to tabulate low-level wave functions.

Summary: The W-infinity symmetry is used to describe the chiral quantum incompressible fluids in both conformal and non-conformal regimes, with different excitations characterized by sizes, energies, and momenta. Analytic results are obtained for the radial shape of excitations, edge reconstruction phenomenon, and energy spectrum of density fluctuations in Laughlin states.

Summary: This study focuses on the disk partition function of open strings, addressing the subtle issue arising from the residual gauge group PSL(2, R). Various methods demonstrate that PSL(2, R) effectively behaves like a group with finite negative volume in the path integral, leading to a simple prescription for computation. The findings are then applied to offer a straightforward rederivation of D-brane tensions.

Summary: This study focuses on the calculation of S-multiplets for two-dimensional Euclidean N = (0, 2) and N = (2, 2) superconformal field theories under the T (T) over bar deformation in perturbation theory. The results indicate that certain indices are unaffected by the deformation, while the thermodynamic Bethe ansatz is useful for studying ground state energies.

Summary: This work introduces a manifestly supersymmetric version of the T(bar)T deformation suitable for (0 + 1)-dimensional theories with N = 1 or N = 2 supersymmetry and presents the corresponding f(Q) deformations. Evidence is provided showing the on-shell equivalence between the f(Q) deformations of N = 1 and N = 2 theories and the dimensionally reduced supercurrent-squared deformations of 2d theories with different levels of supersymmetry. Additionally, two forms of the f(Q) deformation in the N = 1 case are discussed and their equivalence is clarified through analogous deformations in the non-supersymmetric setting.

Summary: We prove that a twist gap in the OPE spectrum implies the existence of quasiprimary operators with infinite spins and twists in a unitary CFT and a similar result holds in a two-dimensional Virasoro-invariant, modular-invariant, unitary CFT. We propose a general formulation of the lightcone bootstrap and summarize the similarity between the two problems.

Summary: In this study, we analyzed the triality fusion category discovered in the c = 1 Kosterlitz-Thouless theory using group theoretical fusion category tools. We computed the simple lines, fusion rules, and F-symbols, and studied the physical implications of this fusion category, including spin selection rule derivation, computation of asymptotic density of states for irreducible representations, and analysis of its anomaly and constraints under renormalization group flow. We also compared our findings with another set of F-symbols for fusion categories with the same fusion rule, highlighting the differences in spin selection rules and providing a comprehensive list of fusion categories with the same fusion rule based on the classification result.

Summary: Recent research has shown that the reconstruction of a black-hole interior is sensitive to knowing the exact coupling of the boundary theory, even if the coupling is irrelevant. By deforming the Sachdev-Ye-Kitaev model with irrelevant coupling, it has been found that half-wormholes and wormholes persist, offering a similar mechanism to address the factorization problem. The study also reveals nontrivial dynamics of saddles in the two-time Sachdev-Ye-Kitaev model as the couplings are varied.
