Compatible Instability: Gauge Constraints of Elasticity Inherited by Electronic Nematic Criticality
W. Joe Meese, Rafael M. Fernandes
Electronic nematicity is widely observed in quantum materials with varying degrees of electronic correlation, manifesting through charge, spin, orbital, or superconducting degrees…
Evidence for ferroaxial order in 1T-TiSe via elastoresistivity measurements
Qianni Jiang, Ezra Day-Roberts, Benito Gonzalez +5
The study of spontaneous symmetry breaking and electronic order is fundamental in condensed matter physics. Hidden order, symmetry-breaking states that elude conventional probes, p…
Ferroaxial and nematic transitions in the charge density wave phase of 1T-TiSe
Sarah Edwards, Elliott Rosenberg, Ilaria Maccari +9
Charge density waves (CDWs) with multi-component order parameters can break unexpected symmetries through the interplay of nearly degenerate instabilities. In the widely investigat…
Microscopic origin of the nemato-elastic coupling and dynamics of hybridized collective nematic-phonon excitations
Morten H. Christensen, Michael Schütt, Avraham Klein +1
Electronically-driven nematic order breaks the rotational symmetry of a system, e.g., through a Pomeranchuk instability of the Fermi surface, with a concomitant distortion of the l…
Theory of Electronic Nematic Criticality Constrained by Elastic Compatibility
W. Joe Meese, Rafael M. Fernandes
The defining property of electronic nematicity -- the spontaneous breaking of rotational symmetry -- implies an unavoidable coupling between the nematic order parameter and elastic…
Charge order-driven nematicity in the nickel-pnictide superconductor BaSrNiAs
Thomas Johnson, Camille Bernal-Choban, Sangjun Lee +8
Nematic order refers to the spontaneous breaking of rotational symmetry while preserving translational symmetry. First identified in classical liquid crystals, nematic order arises…
