Phase transition and evidence of fast-scrambling phase in measurement-only quantum circuit
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Information scrambling is nowadays one of the most important topics in various fields of research. Measurement-only circuit (MoC) exhibits specific information scrambling dynamics,…
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…
Deformation of localized states and state transitions in systems of randomly hopping interacting fermions
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
We numerically study the random-hopping fermions (the Cruetz ladder) with repulsion and investigate how the interactions deform localized eigenstates by means of the one particle-d…
Localization and slow-thermalization in a cluster spin model
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Novel cluster spin model with interactions and disorder is introduced and studied. In specific type of interactions, we find an extensive number of local integrals of motion (LIOMs…
Interplay and competition between disorder and flat band in an interacting Creutz ladder
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
We clarify the interplay and competition between disorder and flat band in the Creutz ladder with inter-particle interactions focusing on the system's dynamics. Without disorder, t…
Flat-band full localization and symmetry-protected topological phase on bilayer lattice systems
Ikuo Ichinose, Takahiro Orito, Yoshihito Kuno
In this work, we present bilayer flat-band Hamiltonians, in which all bulk states are localized and specified by extensive local integrals of motion (LIOMs). The present systems ar…
