Quantum criticality in many-body parafermion chains
Ville Lahtinen, Teresia Mansson, Eddy Ardonne
We construct local generalizations of 3-state Potts models with exotic critical points. We analytically show that these are described by non-diagonal modular invariant partition fu…
A Short Introduction to Topological Quantum Computation
Ville Lahtinen, Jiannis K. Pachos
This review presents an entry-level introduction to topological quantum computation -- quantum computing with anyons. We introduce anyons at the system-independent level of anyon m…
Anatomy of Fermionic Entanglement and Criticality in Kitaev Spin Liquids
Konstantinos Meichanetzidis, Mauro Cirio, Jiannis K. Pachos +1
We analyse in detail the effect of non-trivial band topology on the area law behaviour of the entanglement entropy in Kitaev's honeycomb model. By mapping the translationally invar…
Diagnosing Topological Edge States via Entanglement Monogamy
Konstantinos Meichanetzidis, Jens Eisert, Mauro Cirio +2
Topological phases of matter possess intricate correlation patterns typically probed by entanglement entropies or entanglement spectra. In this work, we propose an alternative appr…
Self-organized pseudo-graphene on grain boundaries in topological band insulators
Robert-Jan Slager, Vladimir Juricic, Ville Lahtinen +1
Semi-metals are characterized by nodal band structures that give rise to exotic electronic properties. The stability of Dirac semi-metals, such as graphene in two spatial dimension…
Realizing all quantum criticalities in symmetry protected cluster models
Ville Lahtinen, Eddy Ardonne
We show that all universality class quantum criticalities emerge when one-dimensional generalized cluster models are perturbed with Ising or Zeeman terms. Each critical p…
