Emergence symmetry protected topological phase in spatially tuned measurement-only circuit
Yoshihito Kuno, Ikuo Ichinose
Topological phase transition induced by spatially-tuned single-site measurement is investigated in a measurement-only circuit, in which three different types of projective measurem…
Topological pump of quantum chain and Diophantine equation
Yasuhiro Hatsugai, Yoshihito Kuno
A topological pump of the quantum chain is proposed associated with a current due to a local gauge invariance of colored fermions. The invarian…
Purification and scrambling in a chaotic Hamiltonian dynamics with measurements
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Chaotic transverse-field Ising model with measurements exhibits interesting purification dynamics. Ensemble of non-unitary dynamics of a chaotic many-body system with measurements…
Quantum information spreading in random spin chains with topological order
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
Quantum information spreading and scrambling in many-body systems attract interests these days. Tripartite mutual information (TMI) based on operator-based entanglement entropy (EE…
Information spreading and scrambling in disorder-free multiple-spin interacting models
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Tripartite mutual information (TMI) is an efficient observable to quantify the ability of scrambler for unitary time-evolution operator with quenched many-body Hamiltonian. In this…
