Programmable Spin Conversion in Gradient Quantum Matter
Mamoru Matsuo, Yuta Sekino, Hiroyuki Tajima
We propose programmable spin conversion in ultracold gases as gradient quantum matter, whose spin-dependent self-energy varies in space. Quantum kinetic theory shows that a dissipa…
Gyromagnetic Angular Momentum Interconversion in Neutron Stars
Hiroshi Funaki, Yuta Sekino, Hiroyuki Tajima +3
We propose a novel mechanism for angular momentum (AM) exchange between the crust and core of a neutron star (NS) via the gyromagnetic effect. Using extended hydrodynamics, we mode…
Thermomagnetic anomalies in quantum magnon transport caused by tunable junction geometries in cold atomic systems
Yuta Sekino, Yuya Ominato, Hiroyuki Tajima +2
We study magnon-driven spin and heat transport in a magnetic linear junction (MLJ) formed by two ferromagnets in optical lattices linked via linearly aligned bonds. Using the Schwi…
Field-theoretical aspects of one-dimensional Bose and Fermi gases with contact interactions
Yuta Sekino, Yusuke Nishida
We investigate local quantum field theories for one-dimensional (1D) Bose and Fermi gases with contact interactions, which are closely connected with each other by Girardeau's Bose…
Mesoscopic spin transport between strongly interacting Fermi gases
Yuta Sekino, Hiroyuki Tajima, Shun Uchino
We investigate a mesoscopic spin current for strongly interacting Fermi gases through a quantum point contact. Under the situation where spin polarizations in left and right reserv…
Quantum droplet of one-dimensional bosons with a three-body attraction
Yuta Sekino, Yusuke Nishida
Ultracold atoms offer valuable opportunities where interparticle interactions can be controlled at will. In particular, by extinguishing the two-body interaction, one can realize u…
