Symmetry-protected topological scar subspaces
Chihiro Matsui, Thomas Quella, Naoto Tsuji
We propose a framework that extends the notion of symmetry-protected topological properties beyond the ground-state paradigm to dynamically isolated subspaces formed by exceptional…
Unitary and Nonunitary A-D-E minimal models: Coset graph fusion algebras, defects, entropies, SREEs and dilogarithm identities
Paul A. Pearce, Jared Heymann, Thomas Quella
We consider both unitary and nonunitary A-D-E minimal models on the cylinder with topological defects along the non-contractible cycle of the cylinder. We define the coset graph $A…
Revisiting the symmetry-resolved entanglement for non-invertible symmetries in d conformal field theories
Jared Heymann, Thomas Quella
Recently, a framework for computing the symmetry-resolved entanglement entropy for non-invertible symmetries in d conformal field theories has been proposed by Saura-Bastida…
Duality and hidden symmetry breaking in the q-deformed Affleck-Kennedy-Lieb-Tasaki model
Tyler Franke, Thomas Quella
We revisit the question of string order and hidden symmetry breaking in the q-deformed AKLT model, an example of a spin chain that possesses generalized symmetry. We first argue th…
Calibrating the role of entanglement in variational quantum circuits
Azar C. Nakhl, Thomas Quella, Muhammad Usman
Entanglement is a key property of quantum computing that separates it from its classical counterpart, however, its exact role in the performance of quantum algorithms, especially v…
Inducing Heat Reversal in a Three-Qubit Spin Chain
Saleh Naghdi, Thomas Quella, Charles D. Hill
By the standard second law of thermodynamics, heat spontaneously flows from a hotter body to a colder body. However, quantum systems in which quantum correlations play a prominent…
