A microscopic design rule for spin supersolids in triangular-lattice magnets
Ryota Ono, Jun'ichi Ieda, Michiyasu Mori +1
Spin supersolids emerge as a central topic in frustrated magnetism, motivating the search for realization in quantum materials. To this end, we study the origin of exchange anisotr…
Josephson diode effect via a non-equilibrium Rashba system
Michiyasu Mori, Wataru Koshibae, Sadamichi Maekawa
A non-equilibrium state in a Rashba system under an in-plane magnetic field is identified as the origin of the Josephson diode effect. This state is induced by a current bias--nece…
Magnetic Phase Diagram of Frustrated Spin Ladder
T. Sugimoto, M. Mori, T. Tohyama +1
Frustrated spin ladders show magnetization plateaux depending on the rung-exchange interaction and frustration defined by the ratio of first and second neighbor exchange interactio…
Temperature Dependence of Thermopower in Strongly Correlated Multiorbital Systems
M. Sekino, S. Okamoto, W. Koshibae +2
Temperature dependence of thermopower in the multiorbital Hubbard model is studied by using the dynamical mean-field theory with the non-crossing approximation impurity solver. It…
Quantum Dynamics of a Driven Correlated System Coupled to Phonons
Lev Vidmar, Janez Bonca, Takami Tohyama +1
Nonequilibrium interplay between charge, spin and lattice degrees of freedom on a square lattice is studied for a single charge carrier doped in the t-J-Holstein model. In the pres…
Non-monotonic temperature dependence of thermopower in strongly correlated electron systems
M. Matsuo, S. Okamoto, W. Koshibae +2
We examine the temperature dependence of thermopower in the single band Hubbard model using dynamical mean-field theory. The strong Coulomb interaction brings about the coherent-to…
