Time-reversal symmetry breaking phase and gapped surface states in d-wave nanoscale superconductors
Yuki Nagai, Yukihiro Ota, K. Tanaka
We solve the Bogoliubov-de Gennes equations self-consistently for d-wave superconductors with [110] surfaces. We find spontaneous breaking of time-reversal symmetry (TRS) caused by…

Time-reversal symmetry breaking and gapped surface states due to spontaneous emergence of new order in -wave nanoislands
Yuki Nagai, Yukihiro Ota, K. Tanaka
We solve the Bogoliubov-de Gennes equations self-consistently for the -wave order parameter in nanoscale -wave systems with [110] surfaces and show that spontaneous time-reve…

Emission of continuous coherent terahertz waves with tunable frequency by intrinsic Josephson junctions
Masashi Tachiki, Mikio Iizuka, Kazuo Minami +2
We present a mechanism for emission of electromagnetic terahertz waves by simulation. High superconductors form naturally stacked Josephson junctions. When an external curr…
