Chiral to Nematic Crossover in the Superconducting State of 4Hb-TaS
I. Silber, S. Mathimalar, I. Mangel +10
Most superconductors have an isotropic, single component order parameter, and are well described by the BCS theory for superconductivity. Unconventional, multiple components superc…
Defect-induced electronic smectic state at the surface of nematic materials
Aritra Lahiri, Avraham Klein, Rafael M. Fernandes
Due to the intertwining between electronic nematic and elastic degrees of freedom, lattice defects and structural inhomogeneities commonly found in crystals can have a significant…
Synergetic ferroelectricity and superconductivity in zero-density Dirac semimetals near quantum criticality
Vladyslav Kozii, Avraham Klein, Rafael M. Fernandes +1
We study superconductivity in a three-dimensional zero-density Dirac semimetal in proximity to a ferroelectric quantum critical point. We find that the interplay of criticality, in…
Multiple pairing states and temperature-dependent gap anisotropy for superconductivity near a nematic quantum-critical point
Avraham Klein, Yi-Ming Wu, Andrey Chubukov
Superconductivity in many strongly correlated materials appears in proximity to a density-wave or nematic order and is believed to be mediated by quantum-critical (QC) fluctuations…
Superconductivity near a nematic quantum critical point -- the interplay between hot and lukewarm regions
Avraham Klein, Andrey Chubukov
We present a strong coupling dynamical theory of the superconducting transition in a metal near a QCP towards nematic order. We use a fermion-boson model, in which we treat…
