Spectral Crossings Diagnose Multiply Quantized Vortex Splitting
Jongheon Baek, Hiroyuki Tajima, Gihwan Nam
A charge- coupling vortex can remain as one fused order- zero or split into nearby unit-charge zeros after weak symmetry breaking. The two configurations have the same to…
Tunable Mediated Interactions Near Spontaneous Symmetry Breaking: From Yukawa to Coulomb and Dzyaloshinskii--Moriya Interactions
Hoshu Hiyane, Hiroyuki Tajima
We propose a realization of tunable long-range mediated interactions generated by Nambu-Goldstone (NG) modes near spontaneous symmetry breaking. An effective exchange interaction e…
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…
Nonequilibrium Andreev transport at the QGP-2SC interface
Tingyu Zhang, Honoka Hoshino, Hiroyuki Tajima +2
We discuss a nonequilibrium Andreev reflection at an interface between quark-gluon plasma (QGP) and two-flavor color superconducting (2SC) quark matter. Based on the Schwinger-Keld…
Two-body loss dynamics as a probe of dynamical bulk viscosity in ultracold atomic gases
Tingyu Zhang, Hiroyuki Tajima, Takeo Kato
We show that the equilibrium connected correlation of the two-body loss rate provides access to the dynamical bulk viscosity in weakly dissipative quantum gases. Starting from the…
Thermal Spin Polarization Driven by Nuclear Spin-Orbit Coupling in Neutron Star Pasta
Hiroyuki Tajima, Yuta Sekino, Hiroshi Funaki +3
We discuss anomalous spin polarization on the surface of nuclear pasta in a neutron star, driven by a nuclear spin-orbit interaction. We present an effective two-band model of surf…
Schwinger-Keldysh approach to tunneling transport at a hadron-quark interface
Tingyu Zhang, Hiroyuki Tajima, Motoi Tachibana
We theoretically discuss quantum tunneling transport and frictions at a hadron-quark matter interface based on the Schwinger-Keldysh approach combined with the tunneling Hamiltonia…
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…
Probing Goldstino excitation through the tunneling transport in a Bose-Fermi mixture with explicitly broken supersymmetry
Tingyu Zhang, Yixin Guo, Hiroyuki Tajima +1
We theoretically investigate the tunneling transport in a repulsively interacting ultracold Bose-Fermi mixture. A two-terminal model is applied to such a mixture and the supersymme…
Thermomagnetic Anomalies by Magnonic Criticality in Ultracold Atomic Transport
Yuta Sekino, Yuya Ominato, Hiroyuki Tajima +2
We investigate thermomagnetic transport in an ultracold atomic system with two ferromagnets linked via a magnetic quantum point contact. Using nonequilibrium Green's function appro…
Magnonic spin current shot noise in an itinerant Fermi gas
Tingyu Zhang, Hiroyuki Tajima, Haozhao Liang
Spin transport phenomena at strongly-correlated interfaces play central roles in fundamental physics as well as spintronic applications. To anatomize spin-transport carriers, we pr…
