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…
Electron dynamics induced by quantum cat-state light
Shohei Imai, Atsushi Ono, Naoto Tsuji
We present an effective theory for describing electron dynamics driven by an optical external field in a Schrödinger's cat state. We show that the reduced electron density matrix…
Quantum many-body scars with unconventional superconducting pairing symmetries via multibody interactions
Shohei Imai, Naoto Tsuji
We present a systematic framework to construct model Hamiltonians that have unconventional superconducting pairing states as exact energy eigenstates, by incorporating multibody in…
Boundary dissipative spin chains with partial solvability inherited from system Hamiltonians
Chihiro Matsui, Naoto Tsuji
Partial solvability plays an important role in the context of statistical mechanics, since it has turned out to be closely related to the emergence of quantum many-body scar states…
