Scar subspaces stabilized by algebraic closure: Beyond equally-spaced spectra and exact solvability
Chihiro Matsui
We construct a class of quantum many-body systems hosting an -invariant scar subspace, extending the conventional paradigm of quantum many-body scars beyond equal…
Weak ergodicity breaking with isolated integrable sectors
Hosho Katsura, Chihiro Matsui, Chiara Paletta +1
We consider spin chain models with local Hamiltonians that display weak ergodicity breaking. In these models, the majority of the eigenstates are thermal, but there is a distinguis…
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…
Exactly solvable subspaces of non-integrable spin chains with boundaries and quasiparticle interactions
Chihiro Matsui
We propose two new strategies to construct a family of non-integrable spin chains with exactly solvable subspace based on the idea of quasiparticle excitations from the matrix prod…
Exact steady states of the impurity-doped XXZ spin chain coupled to dissipators
Chihiro Matsui, Naoto Tsuji
We give an exact matrix product steady state and matrix product forms of local observables for the bulk impurity-doped XXZ spin model coupled to dissipators at both ends, whose dyn…
Nonequilibrium physics in integrable systems and spin-flip non-invariant conserved quantities
Chihiro Matsui
Recently found spin-flip non-invariant (SFNI) conserved quantities play important roles in discussing nonequilibrium physics of the XXZ model. The representative examples are the g…
