We consider a Josephson junction bilayer consisting of two tunnel-coupled two-dimensional
electron gas layers with Rashba spin-orbit interaction, proximitized by a top and bottom s …

Despite intensive searches for topological superconductors, the realization of topological
superconductivity remains under debate. Previous proposals for the topological s-wave, p …

Unconventional superconductivity and magnetism are intertwined on a microscopic level in
a wide class of materials, including high-T c cuprates, iron pnictides, and heavy-fermion …

Bloch wave functions of electrons have properties called quantum geometry, which has
recently attracted much attention as the origin of intriguing physical phenomena. In this …

Magnetic skyrmions are nanoscale spin configurations that are efficiently created and
manipulated. They hold great promises for next-generation spintronics applications. In …

We show that an in-plane magnetic field can drive two-dimensional spin-orbit-coupled
systems under the superconducting proximity effect into a gapless phase where parts of the …

We study the effects of quasidisorder and Anderson disorder on a two-dimensional
topological superconductor with an applied external magnetic field. The cases of ap-wave …

We show that finite current in superconductors can induce topological phase transitions, as
a result of the deformation of the quasiparticle spectrum by a finite center-of-mass (COM) …

We present a detailed investigation of the topological phases and Majorana fermion (MF)
excitations that arise from the bulk interplay between (un) conventional one-and two-band …

Chiral symmetry plays an indispensable role in topological classifications as well as in the
understanding of the origin of bulk or boundary flat bands. The conventional definition of …
