Topological bound states in interacting Su–Schrieffer–Heeger rings
AM Marques, RG Dias - Journal of Physics: Condensed Matter, 2018 - iopscience.iop.org
We study two-particle states in a Su–Schrieffer–Heeger (SSH) chain with periodic boundary
conditions and nearest-neighbor (NN) interactions. The system is mapped into a problem of …

Floquet engineering of long-range -wave superconductivity: Beyond the high-frequency limit
It has been shown that long-range p-wave superconductivity in a Kitaev chain can be
engineered via an ac field with a high frequency [M. Benito, Phys. Rev. B 90, 205127 (2014) …
