Fractionalization-Induced Time-Reversal Symmetry Breaking at Continuous Superconducting Transitions in Low-Symmetry Kondo Lattices
Wonjune Choi, Shi-Zeng Lin
In conventional Landau theory, simultaneous continuous onset of superconductivity and the breaking of additional symmetries generally requires a multidimensional order parameter or…
Measuring Anyonic Exchange Phases Using Two-Dimensional Coherent Spectroscopy
Nico Kirchner, Wonjune Choi, Frank Pollmann
Identifying experimental signatures of anyons, which exhibit fractional exchange statistics, remains a central challenge in the study of two-dimensional topologically ordered syste…
Characterizing the Entanglement of Anyonic Systems using the Anyonic Partial Transpose
Nico Kirchner, Wonjune Choi, Frank Pollmann
Entanglement of mixed quantum states can be quantified using the partial transpose and its corresponding entanglement measure, the logarithmic negativity. Recently, the notion of p…
Finite Temperature Entanglement Negativity of Fermionic Symmetry Protected Topological Phases and Quantum Critical Points in One Dimension
Wonjune Choi, Michael Knap, Frank Pollmann
We study the logarithmic entanglement negativity of symmetry-protected topological (SPT) phases and quantum critical points (QCPs) of one-dimensional noninteracting fermions at fin…
