Electronic instabilities of kagome metals: saddle points and Landau theory
Takamori Park, Mengxing Ye, Leon Balents
We study electronic instabilities of a kagome metal with a Fermi energy close to saddle points at the hexagonal Brillouin zone face centers. Using parquet renormalization group, we…
Phonon Hall Viscosity in Magnetic Insulators
Mengxing Ye, Lucile Savary, Leon Balents
The Phonon Hall Viscosity is the leading term evincing time-reversal symmetry breaking in the low energy description of lattice phonons. It may generate phonon Berry curvature, and…
Temperature evolution of the phonon dynamics in the Kitaev spin liquid
Kexin Feng, Mengxing Ye, Natalia B. Perkins
Here we present a study of the phonon dynamics in the honeycomb Kitaev spin model at finite temperatures. We show that the fractionalized spin excitations of the Kitaev spin liquid…
Current Switching of Valley Polarization in Twisted Bilayer Graphene
Xuzhe Ying, Mengxing Ye, Leon Balents
Twisted bilayer graphene (TBG) aligned with hexagonal boron nitride (h-BN) substrate can exhibit an anomalous Hall effect at 3/4 filling due to the spontaneous valley polarization…
Phonon dynamics in the Kitaev spin liquid
Mengxing Ye, Rafael M. Fernandes, Natalia B. Perkins
The search for fractionalization in quantum spin liquids largely relies on their decoupling with the environment. However, the spin-lattice interaction is inevitable in a real sett…
The Hubbard model on a triangular lattice -- pseudogap due to spin-density-wave fluctuations
Mengxing Ye, Andrey V. Chubukov
We calculate the fermionic spectral function in the spiral spin-density-wave (SDW) state of the Hubbard model on a quasi-2D triangular lattice at small but finite tempera…
