Motivated by recent proposals to realize Majorana bound states in chains and arrays of
magnetic atoms deposited on top of a superconductor, we study the topological properties of …

Recently one-dimensional topological phases are gaining increasing attentions. Like two-
and three-dimensional ones, Onedimensional systems are important in a complete …

Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this
context, a reentrant topological phase, characterized by the emergence of quasi zero …

Motivated by recent experimental realizations of topological edge states in Su-Schrieffer-
Heeger (SSH) chains, we theoretically study a ladder system whose legs are comprised of …

Topological superconductors give rise to unconventional superconductivity, which is mainly
characterized by the symmetry of the superconducting pairing amplitude. However, since the …

The (one-dimensional) Su-Schrieffer-Heeger Hamiltonian, augmented by spin-orbit coupling
and longer-range hop**, is studied at half filling for an even number of sites. The ground …

Majorana bound states are interesting candidates for applications in topological quantum
computation. Low-energy models allowing one to grasp their properties are hence …

Ever since its first proposal in 1976, Jackiw-Rebbi zero-mode has been drawing extensive
attention for its charming properties including charge fractionalization, topologically …

In this Rapid Communication we show that Rashba-based topological superconductor
nanowires, where the spin-orbit coupling may change its sign, support three topological …

Abstract A $\boldsymbol {2\pi} $ phase shift across a Josephson junction in a topological
superconductor injects vortices into the chiral edge modes at opposite ends of the junction …
