Magnetization process of spin-1/2 Heisenberg antiferromagnets on a layered triangular lattice
Daisuke Yamamoto, Giacomo Marmorini, Ippei Danshita
We study the magnetization process of the spin-1/2 antiferromagnetic Heisenberg model on a layered triangular lattice by means of a numerical cluster mean-field method with a scali…
Umbrella-coplanar transition in the triangular XXZ model with arbitrary spin
Giacomo Marmorini, Daisuke Yamamoto, Ippei Danshita
The quantum triangular XXZ model has recently enjoyed a wealth of new theoretical results, especially in relation to the modeling of the BaCoSbO compound. In particular…
Phase diagram and sweep dynamics of a one-dimensional generalized cluster model
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We numerically study quantum phase transitions and dynamical properties in the one-dimensional cluster model with several interactions by using the time-evolving block decimation m…
Fano resonance through Higgs bound states in tunneling of Nambu-Goldstone modes
Takeru Nakayama, Ippei Danshita, Tetsuro Nikuni +1
We study collective modes of superfluid Bose gases in optical lattices combined with potential barriers. We assume that the system is in the vicinity of the quantum phase transitio…
