Bounds on eigenstate thermalization

Shoki Sugimoto, Ryusuke Hamazaki, Masahito Ueda

The eigenstate thermalization hypothesis (ETH), which asserts that every eigenstate of a many-body quantum system is indistinguishable from a thermal ensemble, plays a pivotal role…

Hermitian and Non-Hermitian Topology from Photon-Mediated Interactions

Federico Roccati, Miguel Bello, Zongping Gong +4

Light can mediate effective dipole-dipole interactions between atoms or quantum emitters coupled to a common environment. Exploiting them to tailor a desired effective Hamiltonian…

Yang-Lee Zeros, Semicircle Theorem, and Nonunitary Criticality in Bardeen-Cooper-Schrieffer Superconductivity

Hongchao Li, Xie-Hang Yu, Masaya Nakagawa +1

Yang and Lee investigated phase transitions in terms of zeros of partition functions, namely, Yang-Lee zeros [Phys. Rev. 87, 404 (1952); Phys. Rev. 87, 410 (1952)]. We show that th…

Three Learning Stages and Accuracy-Efficiency Tradeoff of Restricted Boltzmann Machines

Lennart Dabelow, Masahito Ueda

Restricted Boltzmann Machines (RBMs) offer a versatile architecture for unsupervised machine learning that can in principle approximate any target probability distribution with arb…

Lindbladian Many-Body Localization

Ryusuke Hamazaki, Masaya Nakagawa, Taiki Haga +1

We discover a novel localization transition that alters the dynamics of coherence in disordered many-body spin systems subject to Markovian dissipation. The transition occurs in th…

Exact eigenstates of multicomponent Hubbard models: SU() magnetic pairing, weak ergodicity breaking, and partial integrability

Masaya Nakagawa, Hosho Katsura, Masahito Ueda

We construct exact eigenstates of multicomponent Hubbard models in arbitrary dimensions by generalizing the -pairing mechanism. Our models include the SU() Hubbard model as a…
