Textures and Vortices in d-Wave Fermi Condensates in Atomic Gases
Hiroki M. Adachi, Yasumasa Tsutsumi, Kazushige Machida
Fundamental properties of superfluids with d-wave pairing symmetry are investigated theoretically. We consider neutral atomic Fermi gases in a harmonic trap, the Cooper pairing bei…
Singular and Half-Quantum Vortices and Associated Majorana Particles in Superfluid 3He-A between Parallel Plates
Takuto Kawakami, Yasumasa Tsutsumi, Kazushige Machida
Motivated by a recent experiment on superfluid 3He-A confined in narrow parallel plates using a rotating cryostat, we explore possible vortices stable under magnetic field applied…
Sign reversal of field-angle resolved heat capacity oscillations in a heavy fermion superconductor CeCoIn and pairing symmetry
K. An, T. Sakakibara, R. Settai +4
To identify the superconducting gap symmetry in CeCoIn5 (Tc=2.3 K), we performed angle-resolved specific heat (C_ϕ) measurements in a field rotated around the c-axis down to very l…
Stability of the singular vortex and associated Majorana zero modes in trapped p-wave resonant superfluids of neutral cold atoms
Y. Tsutsumi, K. Machida
The stability conditions for the singular vortex which accompanies Majorana zero modes at the core are investigated for p-wave resonant superfluids of atomic Fermi gases. Within th…
Stable Fractional Vortices in the Cyclic States of Bose-Einstein Condensates
J. A. M. Huhtamäki, T. P. Simula, M. Kobayashi +1
We propose methods to create fractional vortices in the cyclic state of an F = 2 spinor Bose-Einstein condensate by manipulating its internal spin structure using pulsed microwave…
Generic First Order Orientation Transition of Vortex Lattices in Type II Superconductors
Kenta M. Suzuki, Kenji Inoue, Predrag Miranovic +2
First order transition of vortex lattices (VL) observed in various superconductors with four-fold symmetry is explained microscopically by quasi-classical Eilenberger theory combin…
