Persistent-current states originating from the Hilbert space fragmentation in momentum space
Masaya Kunimi, Ippei Danshita
Hilbert space fragmentation (HSF) is a phenomenon that the Hilbert space of an isolated quantum system splits into exponentially many disconnected subsectors. The fragmented system…
Evaluating thermal expectation values by almost ideal sampling with Trotter gates
Shimpei Goto, Ryui Kaneko, Ippei Danshita
We investigate the sampling efficiency for the simulations of quantum many-body systems at finite temperatures when initial sampling states are generated by applying Trotter gates…
Rényi entanglement entropy after a quantum quench starting from insulating states in a free boson system
Daichi Kagamihara, Ryui Kaneko, Shion Yamashika +4
We investigate the time-dependent Rényi entanglement entropy after a quantum quench starting from the Mott-insulating and charge-density-wave states in a one-dimensional free boson…
Resonant superfluidity in the Rabi-coupled spin-dependent Fermi-Hubbard model
Mathias Mikkelsen, Ryui Kaneko, Daichi Kagamihara +1
We investigate the ground-state phase diagram of the one-dimensional attractive Fermi-Hubbard model with spin-dependent hoppings and an on-site Rabi coupling using the density matr…
