Exact Quantum Many-Body Scars in 2D Quantum Gauge Models
Yuan Miao, Linhao Li, Hosho Katsura +1
The paper identifies exact quantum many-body scar states in a two‑dimensional Z₂ gauge model by exploiting its duality to a spin‑½ XY model on bipartite graphs, showing that these…
Exact spectrum and anomalous relaxation in the open disorder-free Sachdev-Ye-Kitaev system
Soshun Ozaki, Hironobu Yoshida, Hosho Katsura
We study a disorder-free variant of the Sachdev-Ye-Kitaev (SYK) model with dissipation within the Gorini-Kossakowski-Sudarshan-Lindblad formalism. By utilizing the integrability of…
Non-equilibirum physics of density-difference dependent Hamiltonian: Quantum Scarring from Emergent Chiral Symmetry
William N Faugno, Hosho Katsura, Tomoki Ozawa
Quantum many-body scars represent a form of weak ergodicity breaking that highlights the unusual physics of thermalization in quantum systems. Understanding scar formation promises…
Quantum transport on Bethe lattices with non-Hermitian sources and a drain
Naomichi Hatano, Hosho Katsura, Kohei Kawabata
We consider quantum transport in a tight-binding model on the Bethe lattice of finite generation, which we expect to be the first step toward analyzing electronic transport in a li…
Towers of Quantum Many-body Scars from Integrable Boundary States
Kazuyuki Sanada, Yuan Miao, Hosho Katsura
We construct several models with multiple quantum many-body scars (QMBS) using integrable boundary states (IBS). Specifically, we focus on the tilted Néel states, which are parame…
Dissipative free fermions in disguise
Kohei Fukai, Hironobu Yoshida, Hosho Katsura
Recently, a class of spin chains known as ``free fermions in disguise'' (FFD) has been discovered, which possess hidden free-fermion spectra even though they are not solvable via t…
