Dynamical structure factor with a pumping approach on a trapped-ion quantum computer
Etienne Granet, Keisuke Murota, Henrik Dreyer +3
Dynamical structure factors (DSF) measured with neutron-scattering experiments provide key insights into the structure of materials. Their computation requires both the preparation…
Semiclassical representation of the Hubbard model
Yuki Yamasaki, Hidemaro Suwa, Cristian D. Batista +1
By revisiting the path-integral formulation of the Hubbard model, we propose a theoretical approach based on a semiclassical approximation employing an unconventional coherent-stat…
Unified Description of Spin-Lattice Coupling and Thermodynamics in the Pyrochlore Heisenberg Antiferromagnet
Masaki Gen, Hidemaro Suwa, Shusaku Imajo +6
We study an extended model to describe the spin-lattice coupling, incorporating individual vibrations of bonds and atomic sites alongside distance-dependent exchange interactions.…
Thermally quenched metastable phase in the Ising model with competing interactions
Hiroshi Oike, Hidemaro Suwa, Yasunori Takahashi +1
Thermal quenching has been used to find metastable materials such as hard steels and metallic glasses. More recently, quenching-based phase control has been applied to correlated e…
