Universality classes of non-Hermitian random matrices
Ryusuke Hamazaki, Kohei Kawabata, Naoto Kura +1
Non-Hermitian random matrices have been utilized in such diverse fields as dissipative and stochastic processes, mesoscopic physics, nuclear physics, and neural networks. However,…
Lieb-Robinson Bounds on Entanglement Gaps from Symmetry-Protected Topology
Zongping Gong, Naoto Kura, Masatoshi Sato +1
A quantum quench is the simplest protocol to investigate nonequilibrium many-body quantum dynamics. Previous studies on the entanglement properties of quenched quantum many-body sy…
Standard Quantum Limit and Heisenberg Limit in Function Estimation
Naoto Kura, Masahito Ueda
Unlike well-established parameter estimation, function estimation faces conceptual and mathematical difficulties despite its enormous potential utility. We establish the fundamenta…
Transient fractality as a mechanism for emergent irreversibility in chaotic Hamiltonian dynamics
Yûto Murashita, Naoto Kura, Masahito Ueda
Understanding irreversibility in macrophysics from reversible microphysics has been the holy grail in statistical physics ever since the mid-19th century. Here the central question…
Finite-error metrological bounds on the multi-parameter Hamiltonian estimation
Naoto Kura, Masahito Ueda
Estimation of multiple parameters in an unknown Hamiltonian is investigated. We present upper and lower bounds on the time required to complete the estimation within a prescribed t…
