Signatures of pair-density wave order in phase-sensitive measurements of LaBaCuO-Nb Josephson junctions and SQUIDs
D. R. Hamilton, G. D. Gu, E. Fradkin +1
The interplay of charge order, spin order, and superconductivity in LaBaCuO creates a complex physical system that hosts several interesting phases, such as two-dim…
Pair-Density-Wave Order and Paired Fractional Quantum Hall Fluids
Luiz H. Santos, Yuxuan Wang, Eduardo Fradkin
The properties of the isotropic incompressible fractional quantum Hall (FQH) state are described by a paired state of composite fermions in zero (effective) magnetic field,…
Dirac Composite Fermions and Emergent Reflection Symmetry about Even Denominator Filling Fractions
Hart Goldman, Eduardo Fradkin
Motivated by the appearance of a `reflection symmetry' in transport experiments and the absence of statistical periodicity in relativistic quantum field theories, we propose a seri…
Helical spin thermoelectrics controlled by a side-coupled magnetic quantum dot in the quantum spin Hall state
P. Roura-Bas, Liliana. Arrachea, Eduardo Fradkin
We study the thermoelectric response of a device containing a pair of helical edge states contacted at the same temperature and chemical potential and connected to an exter…
Bosonization of Fermi liquids in a weak magnetic field
Daniel G. Barci, Eduardo Fradkin, Leonardo Ribeiro
Novel controlled non-perturbative techniques are a must in the study of strongly correlated systems, especially near quantum criticality. One of these techniques, bosonization, has…
Pair Density Waves in Superconducting Vortex Halos
Yuxuan Wang, Stephen D. Edkins, Mohammad H. Hamidian +3
We analyze the interplay between a d-wave uniform superconducting and a pair-density-wave (PDW) order parameter in the neighborhood of a vortex. We develop a phenomenological nonli…
