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…
Simulating Lattice Gauge Theories with Virtual Rishons
David Rogerson, João Barata, Robert M. Konik +2
Classical tensor network and hybrid quantum-classical algorithms are promising candidates for the investigation of real-time properties of lattice gauge theories. We develop here a…
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…
Integrability and lattice discretizations of all Topological Defect Lines in minimal CFTs
Madhav Sinha, Thiago Silva Tavares, Ananda Roy +1
We discuss in this paper the lattice discretizations of all topological defect lines (TDLs) for diagonal, minimal CFTs, using integrable restricted solid-on-solid (RSOS) models. Fo…
Boundary Conditions for the Entanglement Cut in 2D Conformal Field Theories
Ananda Roy, Sergei L. Lukyanov, Hubert Saleur
The entanglement spectra for a subsystem in a spin chain fine-tuned to a quantum-critical point contains signatures of the underlying quantum field theory that governs its low-ener…
