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…
Multifractality and Fock-space localization in many-body localized states: one-particle density matrix perspective
Takahiro Orito, Ken-Ichiro Imura
Many-body localization (MBL) is well characterized in Fock space. To quantify the degree of this Fock space localization, the multifractal dimension is employed; it has been…
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…
Non-thermalized Dynamics of Flat-Band Many-Body Localization
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
We find that a flat-band fermion system with interactions and without disorders exhibits non-thermalized ergodicity-breaking dynamics, an analog of many-body localization (MBL). In…
Exact projector Hamiltonian, local integrals of motion, and many-body localization with topological order
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
In this work, we construct an exact projector Hamiltonian with interactions, which is given by a sum of mutually commuting operators called stabilizers. The model is based on the r…
Effects of power-law correlated disorders in XXZ spin chain: Many-body localized to thermal phase transition and its critical regime
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
We study a canonical many-body-localized (MBL) system with power-law-correlated disorders: spin chain in a random magnetic field. The power-law-correlated disorder…
