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…

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…

4T2R X-ReRAM CiM Array for Variation-tolerant, Low-power, Massively Parallel MAC Operation

Fuyuki Kihara, Seiji Uenohara, Satoshi Awamura +3

Computation-in-Memory (CiM) is attracting attention as a technology that can perform MAC calculations required for AI accelerators, at high speed with low power consumption. Howeve…

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…
