Entanglement entropy dynamics of non-Gaussian states in free boson systems: Random sampling approach
Ryui Kaneko, Daichi Kagamihara, Ippei Danshita
We develop a random sampling method for calculating the time evolution of the Rényi entanglement entropy after a quantum quench from an insulating state in free boson systems. Beca…
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…
Surface criticality in the mixed-field Ising model with sign-inverted next-nearest-neighbor interaction
Yuki Nakamura, Ryui Kaneko, Ippei Danshita
Rydberg atoms in an optical tweezer array have been used as a quantum simulator of the spin- antiferromagnetic Ising model with longitudinal and transverse fields. We suggest…
