Many-Body Bound States in the Continuum
Shoki Sugimoto, Yuto Ashida, Masahito Ueda
A bound state in the continuum (BIC) is a spatially localized energy eigenstate embedded in a continuous spectrum of extended eigenstates. While diverse types of single-particle BI…

Quasiparticles of Decoherence Processes in Open Quantum Many-Body Systems: Incoherentons
Taiki Haga, Masaya Nakagawa, Ryusuke Hamazaki +1
The relaxation dynamics of an open quantum system is determined by the competition between the coherent Hamiltonian dynamics of a system and the dissipative dynamics due to interac…

Circuit analysis of quantum measurement
Yuji Kurotani, Masahito Ueda
We develop a circuit theory that enables us to analyze quantum measurements on a two-level system and on a continuous-variable system on an equal footing. As a measurement scheme a…
