Signatures of fractionalization in the optical phonons of hyperhoneycomb Kitaev magnet -LiIrO
Swetlana Swarup, Susmita Singh, Natalia B. Perkins
In this study, we propose that the signatures of spin fractionalization in quantum magnets can be identified through a detailed analysis of the temperature dependence of the asymme…
Phonon Dynamics in the Chiral Kitaev Spin Liquid
Susmita Singh, P. Peter Stavropoulos, Natalia B. Perkins
We investigate the effect of a magnetic field on the extended Kitaev spin liquid state through phonon dynamics. Using a constrained fermionic self-consistent mean field method, we…
Supersolid Phase in the Diluted Holstein Model
Jingyao Meng, Yuxi Zhang, Rafael M. Fernandes +2
The Holstein model on a square lattice at half-filling has a well-established finite temperature phase transition to an insulating state with long range charge density wave (CDW) o…
Quantum criticality and optical conductivity in a two-valley system
Yasha Gindikin, Songci Li, Alex Levchenko +3
We demonstrate that the optical conductivity of a Fermi liquid (FL) in the absence of umklapp scattering is dramatically affected by the topology of the Fermi surface (FS). Specifi…
Fermi Liquid near a q=0 Charge Quantum Critical Point
R. David Mayrhofer, Peter Wölfle, Andrey V. Chubukov
We analyze the quasiparticle interaction function (the fully dressed and antisymmetrized interaction between fermions) for a two-dimensional Fermi liquid at zero temperature close…
Classification of electronic nematicity in three-dimensional crystals and quasicrystals
Matthias Hecker, Anant Rastogi, Daniel F. Agterberg +1
Electronic nematic order has been reported in a rich landscape of materials, encompassing not only a range of intertwined correlated and topological phenomena, but also different u…
