Phase diagram of an extended parafermion chain
Jurriaan Wouters, Fabian Hassler, Hosho Katsura +1
We study the phase diagram of an extended parafermion chain, which, in addition to terms coupling parafermions on neighbouring sites, also possesses terms involving four sites. Via…
Interrelations among frustration-free models via Witten's conjugation
Jurriaan Wouters, Hosho Katsura, Dirk Schuricht
We apply Witten's conjugation argument [Nucl. Phys. B 202, 253 (1982)] to spin chains, where it allows us to derive frustration-free systems and their exact ground states from know…
Phase diagram of the -Fock parafermion chain with pair hopping
Iman Mahyaeh, Jurriaan Wouters, Dirk Schuricht
We study a tight binding model of -Fock parafermions with single-particle and pair-hopping terms. The phase diagram has four different phases: a gapped phase, a gaple…
Exact ground states for interacting Kitaev chains
Jurriaan Wouters, Hosho Katsura, Dirk Schuricht
We introduce a frustration-free, one-dimensional model of spinless fermions with hopping, p-wave superconducting pairing and alternating chemical potentials. The model possesses tw…
