A topological superconductor is characterized by having a pairing gap in the bulk and
gapless self-hermitian Majorana modes at its boundary. In one dimension, these are zero …

One-dimensional helical liquids can appear at boundaries of certain condensed matter
systems. Two prime examples are the edge of a quantum spin Hall insulator and the hinge …

We propose a tune-free scheme to realize Kramers pairs of Majorana bound states in
recently discovered higher-order topological insulators (HOTIs). We show that, by bringing …

Semiconducting quantum wires defined within two-dimensional electron gases and strongly
coupled to thin superconducting layers have been extensively explored in recent …

We study the crossed Andreev reflection and the nonlocal transport in the proximitized
graphene/superconductor/proximitized graphene junctions with the pseudospin staggered …

We consider a hybrid quantum Hall-superconductor system, where a superconducting finger
with oblique profile is wedged into a two-dimensional electron gas in the presence of a …

We study the proximity effect in a one-dimensional nanowire strongly coupled to a finite
superconductor with a characteristic size which is much shorter than its coherence length …

Hybrid nanostructures consisting of two parallel InAs nanowires connected by an epitaxially
grown superconductor (SC) shell recently became available. Due to the defect-free SC …

We analyze the effects of electron-electron interactions and disorder on a Rashba double-
nanowire setup coupled to an s-wave superconductor, which has been recently proposed as …

We characterize in situ grown parallel nanowires bridged by a superconducting island. The
magnetic-field and temperature dependence of Coulomb blockade peaks measured across …
