Ground-state phase diagram of the SU() Heisenberg model on a plaquette lattice
Ryui Kaneko, Shimpei Goto, Ippei Danshita
We investigate the ground state of the SU() Heisenberg model on a square lattice with spatial anisotropy on each plaquette bond using the tensor-network method based on infinite…

Labeling eigenstates of qubit-cavity systems based on the continuity of qubit occupancy: Detecting resonances to higher excited qubit states
Shimpei Goto, Kazuki Koshino
We propose a new method for labeling the eigenstates of qubit-cavity systems based on the continuity of the qubit occupancy. The labeled eigenstates give a rough estimate of the ev…
