Zero-Field Surface Charge Due to the Gap Suppression in -Wave Superconductors
Ezekiel Sambo Joshua, Hikaru Ueki, Wataru Kohno +1
We perform a microscopic study on the redistribution of electric charge near the surface of a model -wave superconductor cut along the [110] direction, with a Fermi surface appr…
Phenomenology of the chiral -wave state in the hexagonal pnictide superconductor SrPtAs
Hikaru Ueki, Shoma Inagaki, Ryota Tamura +5
The pairing symmetry of the hexagonal pnictide superconductor SrPtAs is discussed with taking into account its multiband structure. The topological chiral -wave state with time-…
Drastic enhancement of the thermal Hall angle in a -wave superconductor
Hikaru Ueki, Hiroki Morita, Marie Ohuchi +1
A drastic enhancement of the thermal Hall angle in -wave superconductors was observed experimentally in a cuprate superconductor and in CeCoIn at low temperatures and very w…
Possibility of chiral -wave state in the hexagonal pnictide superconductor SrPtAs
Hikaru Ueki, Ryota Tamura, Jun Goryo
We discuss the type of pairing in the hexagonal pnictide superconductor SrPtAs, taking into account its multiband structure. The topological chiral -wave state with time-reversa…
Charging in a Superconducting Vortex Due to the Three Force Terms in Augmented Eilenberger Equations
Hikaru Ueki, Marie Ohuchi, Takafumi Kita
We derive augmented Eilenberger equations that incorporate the following missing force terms: (i) the Lorentz force, (ii) the pair-potential gradient (PPG) force, and (iii) the pre…
Charging due to Pair-Potential Gradient in Vortex of Type-II Superconductors
Marie Ohuchi, Hikaru Ueki, Takafumi Kita
Besides the magnetic Lorentz force familiar from the Hall effect in metals and semiconductors, there exists a mechanism for charging peculiar to superconductors that is caused by t…
