Magnetic solitons in a spin-1 Bose-Einstein condensate
Xiao Chai, Di Lao, Kazuya Fujimoto +3
Vector solitons are a type of solitary, or non-spreading wavepacket occurring in a nonlinear medium comprised of multiple components. As such, a variety of synthetic systems can be…
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,…
Constructing neural stationary states for open quantum many-body systems
Nobuyuki Yoshioka, Ryusuke Hamazaki
We propose a new variational scheme based on the neural-network quantum states to simulate the stationary states of open quantum many-body systems. Using the high expressive power…
Theoretical study on thermalization in isolated quantum systems
Ryusuke Hamazaki
Understanding how isolated quantum systems thermalize has recently gathered renewed interest almost 100 years after the first work by von Neumann, thanks to the experimental realiz…
Random-matrix behavior of quantum nonintegrable many-body systems with Dyson's three symmetries
Ryusuke Hamazaki, Masahito Ueda
We propose a one-dimensional nonintegrable spin model with local interactions that covers Dyson's three symmetry classes (classes A, AI, and AII) depending on the values of paramet…
