Lower bounds for Ramsey numbers as a statistical physics problem
Jurriaan Wouters, Aris Giotis, Ross Kang +2
Ramsey's theorem, concerning the guarantee of certain monochromatic patterns in large enough edge-coloured complete graphs, is a fundamental result in combinatorial mathematics. In…
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…
Intersublattice entanglement entropy as an extensive property in antiferromagnets
Dion M. F. Hartmann, Jurriaan J. Wouters, Dirk Schuricht +2
Recent advancements in our understanding of ordered magnets call for a quantification of their entanglement content on an equal footing with classical thermodynamic quantities, suc…
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…
