Topological and dynamical properties of a generalized cluster model in one dimension
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We study the ground-state phase diagram and dynamics of the one-dimensional cluster model with several competing interactions. Paying particular attention to the relation between t…
Topological quantum phase transitions in a Majorana chain with spatial modulation
Takumi Ohta, Keisuke Totsuka
We numerically study the quantum phase transitions and the stability of Majorana zero modes in a generalized Kitaev model in one dimension when the chemical potential is periodical…
Phase diagram and sweep dynamics of a one-dimensional generalized cluster model
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We numerically study quantum phase transitions and dynamical properties in the one-dimensional cluster model with several interactions by using the time-evolving block decimation m…
Quantum Transport in Ladder-Type Networks: Role of nonlinearity, topology and spin
K. Nakamura, D. Matrasulov, G. Milibaeva +4
We investigate quantum transport of electrons, phase solitons, etc. through mesoscopic networks of zero-dimensional quantum dots. Straight and circular ladders are chosen as networ…
