A hierarchy of exactly solvable spin-1/2 chains with so(N)_1 critical points
Ville Lahtinen, Teresia Mansson, Eddy Ardonne
We construct a hierarchy of exactly solvable spin-1/2 chains with so(N)_1 critical points. Our construction is based on the framework of condensate-induced transitions between topo…
Topological invariant for generic 1D time reversal symmetric superconductors in class DIII
Jan Carl Budich, Eddy Ardonne
A one dimensional time reversal symmetric topological superconductor (symmetry class DIII) features a single Kramers pair of Majorana bound states at each of its ends. These hologr…
Equivalent topological invariants for one-dimensional Majorana wires in symmetry class D
Jan Carl Budich, Eddy Ardonne
Topological superconductors in one spatial dimension exhibiting a single Majorana bound state at each end are distinguished from trivial gapped systems by a Z_2 topological invaria…
Unraveling of the fractional topological phase in one-dimensional flatbands with nontrivial topology
Jan Carl Budich, Eddy Ardonne
We consider a topologically non-trivial flat band structure in one spatial dimension in the presence of nearest and next nearest neighbor Hubbard interaction. The non-interacting b…
Anyonic quantum spin chains: Spin-1 generalizations and topological stability
Charlotte Gils, Eddy Ardonne, Simon Trebst +4
There are many interesting parallels between systems of interacting non-Abelian anyons and quantum magnetism, occuring in ordinary SU(2) quantum magnets. Here we consider theories…
