Two-dimensional second-order topological superconductors host zero-dimensional
Majorana bound states at their boundaries. In this work, focusing on rotation-invariant …

Topological superconductors are exotic gapped phases of matter hosting Majorana mid-gap
states on their boundaries. In conventional three-dimensional topological superconductors …

A higher-order topological superconductor can experience topological phase transitions
driven by variations in a bulk parameter without closing the bulk gap. This presents a …

Conventional topological superconductors are fully gapped in the bulk but host gapless
Majorana modes on their boundaries. We instead focus on a new class of superconductors …

We demonstrate that level crossings at the Fermi energy serve as robust indicators for
higher-order topology in two-dimensional superconductors of symmetry class D. These …

We study theoretically second-order topological superconductors characterized by the
presence of pairs of zero-energy Majorana corner states. We uncover a quadrupole spin …

A two-dimensional second-order topological superconductor exhibits a finite gap in both
bulk and edges, with the nontrivial topology manifesting itself through Majorana zero modes …

The interplay of time-reversal and n-fold rotation symmetries (n= 2, 4, 6) is known to bring a
new class of topological crystalline insulators (TCIs) having n surface Dirac cones due to a …

Higher-order topological phases host robust boundary states at the boundary of the
boundary, which can be interpreted from their boundary topology. In this work, we show that …

We classify discrete-rotation symmetric topological crystalline superconductors (TCS) in two
dimensions and provide the criteria for a zero-energy Majorana bound state (MBS) to be …
