Rectification in Nonequilibrium Steady States of Open Many-Body Systems
Kazuki Yamamoto, Yuto Ashida, Norio Kawakami
We study how translationally invariant couplings of many-particle systems and nonequilibrium baths can be used to rectify particle currents, for which we consider minimal setups to…
PT-symmetric non-Hermitian quantum many-body system using ultracold atoms in an optical lattice with controlled dissipation
Yosuke Takasu, Tomoya Yagami, Yuto Ashida +3
We report our realization of a parity-time (PT) symmetric non-Hermitian many-body system using cold atoms with dissipation. After developing a theoretical framework on PT-symmetric…
Quantum Rydberg Central Spin Model
Yuto Ashida, Tao Shi, Richard Schmidt +3
We consider dynamics of a Rydberg impurity in a cloud of ultracold bosonic atoms in which the Rydberg electron can undergo spin-changing collisions with surrounding atoms. This sys…
