Nonlinear sigma models, antiperiodic boundary conditions, spin chains, and 't Hooft anomalies
Nicholas Read, Hubert Saleur
We consider two sets of related models: initially, these are antiferromagnetic spin chains with sites of spin , and the nonlinear sigma model in two dimension…
Lattice Topological Defects in Non-Unitary Conformal Field Theories
Madhav Sinha, Thiago Silva Tavares, Hubert Saleur +1
Topological defects play a fundamental role in the investigation of symmetries in quantum field theories. For conformal field theories in two space-time dimensions, it is possible…
Two-point functions in boundary loop models
Max Downing, Jesper Lykke Jacobsen, Rongvoram Nivesvivat +1
Using techniques of conformal bootstrap, we propose analytical expressions for a large class of two-point functions of bulk fields in critical loop models defined on the upper-half…
Diagonal boundary conditions in critical loop models
Max Downing, Jesper Lykke Jacobsen, Rongvoram Nivesvivat +2
In critical loop models, we define diagonal boundaries as boundaries that couple to diagonal fields only. Using analytic bootstrap methods, we show that diagonal boundaries are cha…
Spaces of states of the two-dimensional O(n) and Potts models
Jesper Lykke Jacobsen, Sylvain Ribault, Hubert Saleur
We determine the spaces of states of the two-dimensional and -state Potts models with generic parameters as representations of their known symmetry al…
Signatures of Topological Symmetries on a Noisy Quantum Simulator
Christopher Lamb, Robert M. Konik, Hubert Saleur +1
Topological symmetries, invertible and otherwise, play a fundamental role in the investigation of quantum field theories. Despite their ubiquitous importance across a multitude of…
