Hidden Quantum Geometry in Bilayer Exciton Condensates
Xuzhe Ying, Benjamin T. Zhou
When an electron-doped layer is stacked with a hole-doped layer with approximately equal carrier density, inter-layer Coulomb interaction turns the bilayer system into an exciton c…
Quantum metric driven transition between superfluid and incoherent fluid
Xuzhe Ying, Kangle Li
We study the interplay between repulsive interaction and superfluidity in flat band system. We consider spatially indirect excitons in the Lieb lattice bilayer as an example. We sh…
Topological order in interacting semimetals
Jinmin Yi, Xuzhe Ying, Lei Gioia +1
It has recently been demonstrated that it is possible to open a gap in a magnetic Weyl semimetal, while preserving the chiral anomaly along with the charge conservation and transla…
Dynamical Effects from Anomaly: Modified Electrodynamics in Weyl Semimetal
Xuzhe Ying, A. A. Burkov, Chong Wang
We discuss the modified quantum electrodynamics from a time-reversal-breaking Weyl semimetal coupled with a gauge (electromagnetic) field. A key role is played by the soft d…
Emergent anomalies and generalized Luttinger theorems in metals and semimetals
Chong Wang, Alexander Hickey, Xuzhe Ying +1
Luttinger's theorem connects a basic microscopic property of a given metallic crystalline material, the number of electrons per unit cell, to the volume, enclosed by its Fermi surf…
Change of Corner Charge and Adiabatic Current Distribution in Two Dimensional Insulators with Inversion Symmetry
Xuzhe Ying
We discuss the change of the corner charge for noninteracting two dimensional insulators with inversion symmetry undergoing adiabatic evolution. We show that the change of the corn…
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…
Plasmonic Tuning of the Near Field Heat Transfer in Double Layer Graphene
Xuzhe Ying, Alex Kamenev
We discuss the non-radiative heat transfer in non-equilibrium double layer graphene system. We show that at the neutrality point the heat exchange is dominated by the inter-layer p…
On topological transitions in metals
Xuzhe Ying, Alex Kamenev
We investigate if a sharp topological transition in a metal with a large Fermi surface may be detected in transport measurements. In particular, we address if a skew scattering and…
Symmetry Protected Topological Metals
Xuzhe Ying, Alex Kamenev
We show that sharply defined topological quantum phase transitions are not limited to states of matter with gapped electronic spectra. Such transitions may also occur between two g…
