Systematic modulation of superconducting gap dynamics in YBCO|BNT|YBCO Josephson Junctions through THz field interaction and BNT ferroelectric barrier
Sukhanidhan Singh, Muthukkumaran Karthikeyan, Geoffrey Chanda +5
The paper reports that inserting a ferroelectric Bi0.5Na0.5TiO3 (BNT) barrier into YBa2Cu3O7‑x (YBCO) Josephson junctions allows the superconducting gap and critical current to be…

Non-Hermitian Dirac Vortex: Minimal Theory for Topological-Cavity Surface-Emitting Laser
Zong-Liang Li, Guang-Rui Li, Le-Chen Yang +2
We construct a non-Hermitian Dirac-vortex model that combines a complex-mass winding with an infinite-imaginary-potential boundary, extending the Jackiw-Rossi and neutrino-billiard…
