Environment-matrix-product operator for boundary-free large-scale quantum many-body simulations
Souta Shimozono, Chisa Hotta
We propose an alternative to the infinite density-matrix renormalization approach for accessing quantum many-body states within a finite-size calculation that faithfully mimics the…
Scan calculation of the density of states: real space cluster perturbation theory applied to inhomogeneous Hubbard model in one dimension
Kaito Matsuki, Chisa Hotta, Kenichi Asano
We present the spectral analysis of a one-dimensional Hubbard model with a parabolic potential, using a real-space cluster perturbation theory (rCPT) designed to study spatially in…
Dynamical dimerization and subdiffusive transport of strongly correlated neutral-ionic systems coupled to lattices
Yuta Sakai, Chisa Hotta
We study the Monte Carlo dynamics of strongly correlated classical particles coupled to lattice degrees of freedom that exhibit the neutral-ionic transitions in one dimension, rele…
Effective spin model with anisotropic exchange interactions for the spin-orbit coupled Hubbard model at half-filling
Ryo Makuta, Chisa Hotta
Spin-orbit coupling (SOC) in noncentrosymmetric materials is the source of incommensurate magnetic structures. In semiconductors, it drives the Rashba spin splitting and spin momen…
Spinor ice correlation in flat-band electronic states on kagome and pyrochlore lattices with spin-orbit coupling
Hiroki Nakai, Masafumi Udagawa, Chisa Hotta
We investigate the emergence and transformation of pinch-point singularities in the excitation spectrum of electronic flat band systems on kagome and pyrochlore lattices with spin-…
