Simulation method for evaporative cooling of trapped Bose gases at finite temperatures
Emiko Arahata, Tetsuro Nikuni
We develop a simulation method for evaporative cooling of trapped Bose-Einstein condensate at finite temperatures using Zaremba-Nikuni-Griffin (ZNG) formalism. ZNG formalism includ…
Ground-state and Excitation spectra of Bose-Fermi Mixtures in a Three-Dimensional Optical Lattice
Rei Hatsuda, Emiko Arahata
Motivated by recent developments in the experimental study of Bose-Fermi mixtures, we investigate ground-state phase diagrams and excitation spectra for Bose-Fermi mixtures in a th…
Cooperon condensation and intra-valley pairing states in honeycomb Dirac systems
Shunji Tsuchiya, Jun Goryo, Emiko Arahata +1
Motivated by recent developments in the experimental study of superconducting graphene and transition metal dichalcogenides, we investigate superconductivity of the Kane-Mele (KM)…
Ginzburg-Landau description of twin boundaries in noncentrosymmetric superconductors
Michael Achermann, Titus Neupert, Emiko Arahata +1
We study theoretically a model for twin boundaries in superconductors with Rashba spin-orbit coupling, which can be relevant to both three-dimensional noncentrosymmetric tetragonal…
DC conductivity in an s-wave superconducting single vortex system
Emiko Arahata, Yusuke Kato
We study dynamics of a two-dimensional s-wave superconductor in the presence of a moving single vortex. Our analysis is based on the quasiclassical theory including the Hall term,…
Theory of the Two-Particle Emission from Superfluid Fermi Gases in the BCS-BEC Crossover
Emiko Arahata, Tetsuro Nikuni
We present a theory of the emission of fermion pairs from a superfluid Fermi gas induced by a photon absorption. In the solid state physics, this type of process is called double p…
