Higgs and Nambu-Goldstone modes in condensed matter physics
Naoto Tsuji, Ippei Danshita, Shunji Tsuchiya
Collective dynamics of many particle systems is tightly linked to their underlying symmetry and phase transitions. Higgs and Nambu-Goldstone modes are, respectively, collective amp…
Quantum many-body scars in the Bose-Hubbard model with a three-body constraint
Ryui Kaneko, Masaya Kunimi, Ippei Danshita
We uncover the exact athermal eigenstates in the Bose-Hubbard (BH) model with a three-body constraint, motivated by the exact construction of quantum many-body scar (QMBS) states i…
Discrete-phase-space method for driven-dissipative dynamics of strongly interacting bosons in optical lattices
Kazuma Nagao, Ippei Danshita, Seiji Yunoki
We develop a discrete truncated Wigner method to analyze the real-time evolution of dissipative SU() spin systems coupled with a Markovian environment. This semiclassical…
Relation between the noise correlations and the spin structure factor for Mott-insulating states in SU Hubbard models
Mathias Mikkelsen, Ippei Danshita
It is well established that the noise correlations measured by time-of-flight imaging in cold-atom experiments, which correspond to the density-density correlations in the momentum…
Dynamics of correlation spreading in low-dimensional transverse-field Ising models
Ryui Kaneko, Ippei Danshita
We investigate the dynamical spreading of spatial correlations after a quantum quench starting from a magnetically disordered state in the transverse-field Ising model at one (1D)…
