Ground-state phase diagram of the one-dimensional $t$ - $J_{s}$ - $J_{τ}$ model at quarter filling

Yuya Kurebayashi, Hiroki Oshiyama, Naokazu Shibata

We study the ground state of the one-dimensional " $t$ - $J_{s}$ - $J_{τ}$ model," which is a variant of the $t$ - $J$ model with additional channel degree of freedom. The model is not only a…

Kibble-Zurek mechanism in a Dissipative Transverse Ising Chain

Hiroki Oshiyama, Naokazu Shibata, Sei Suzuki

We study the Kibble-Zurek mechanism in the transverse Ising chain coupled to a dissipative boson bath, making use of a new numerical method with the infinite time evolving block de…

Probing the Universality of Topological Defect Formation in a Quantum Annealer: Kibble-Zurek Mechanism and Beyond

Yuki Bando, Yuki Susa, Hiroki Oshiyama +7

The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is th…
