Floquet engineering Higgs dynamics in time-periodic superconductors
Tobias Kuhn, Björn Sothmann, Jorge Cayao
Higgs modes emerge in superconductors as collective excitations of the order parameter amplitude when periodically driven by electromagnetic radiation. In this work, we develop a F…
Enhancing the Josephson diode effect with Majorana bound states
Jorge Cayao, Naoto Nagaosa, Yukio Tanaka
We consider phase-biased Josephson junctions with spin-orbit coupling under external magnetic fields and study the emergence of the Josephson diode effect in the presence of Majora…
Non-Hermitian phase-biased Josephson junctions
Jorge Cayao, Masatoshi Sato
We study non-Hermitian Josephson junctions formed by superconductors with a finite phase difference under non-Hermiticity, which naturally appears due to coupling to normal reservo…
Nonlocality of Majorana bound states revealed by electron waiting times in a topological Andreev interferometer
Paramita Dutta, Jorge Cayao, Annica M. Black-Schaffer +1
The analysis of waiting times of electron transfers has recently become experimentally accessible owing to advances in noninvasive probes working in the short-time regime. We study…
Controllable odd-frequency Cooper pairs in multi-superconductor Josephson junctions
Jorge Cayao, Pablo Burset, Yukio Tanaka
We consider Josephson junctions formed by multiple superconductors with distinct phases and explore the formation of nonlocal or inter-superconductor pair correlations. We find tha…
Exceptional degeneracies in non-Hermitian Rashba semiconductors
Jorge Cayao
Exceptional points are spectral degeneracies of non-Hermitian systems where eigenvalues and eigenvectors coalesce, inducing unique topological phases that have no counterpart in th…
