Quantum Electronic Circuits for Multicritical Ising Models
Ananda Roy
Multicritical Ising models and their perturbations are paradigmatic models of statistical mechanics. In two space-time dimensions, these models provide a fertile testbed for invest…
Ising Meson Spectroscopy on a Noisy Digital Quantum Simulator
Christopher Lamb, Yicheng Tang, Robert Davis +1
Quantum simulation has the potential to be an indispensable technique for the investigation of non-perturbative phenomena in strongly-interacting quantum field theories (QFTs). In…
Soliton Confinement in a Quantum Circuit
Ananda Roy, Sergei L. Lukyanov
Confinement of topological excitations into particle-like states - typically associated with theories of elementary particles - are known to occur in condensed matter systems, aris…
Entanglement entropy and negativity in the Ising model with defects
David Rogerson, Frank Pollmann, Ananda Roy
Defects in two-dimensional conformal field theories (CFTs) contain signatures of their characteristics. In this work, we compute the entanglement entropy (EE) and the entanglement…
Entanglement entropy in critical quantum spin chains with boundaries and defects
Ananda Roy, Hubert Saleur
Entanglement entropy (EE) in critical quantum spin chains described by 1+1D conformal field theories contains signatures of the universal characteristics of the field theory. Bound…
Entanglement entropy in the Ising model with topological defects
Ananda Roy, Hubert Saleur
Entanglement entropy~(EE) contains signatures of many universal properties of conformal field theories~(CFTs), especially in the presence of boundaries or defects. In particular, {…
