Spin Waves and Dirac Magnons in a Honeycomb Lattice Zig-zag Antiferromagnet BaNi2(AsO4)2
Bin Gao, Tong Chen, Chong Wang +5
The topological properties of massive and massless fermionic quasiparticles have been intensively investigated over the past decade in topological materials without magnetism. Rece…
Non-zero momentum requires long-range entanglement
Lei Gioia, Chong Wang
We show that a quantum state in a lattice spin (boson) system must be long-range entangled if it has non-zero lattice momentum, i.e. if it is an eigenstate of the translation symme…
Electron-phonon coupling and superconductivity in an alkaline earth hydride CaH at high pressures
Hyunsoo Jeon, Chongze Wang, Shuyuan Liu +3
Recently, an alkaline earth hydride CaH having a sodalitelike clathrate structure has been experimentally synthesized at megabar pressures with a maximum of 215 K, compar…
Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Weicheng Ye, Meng Guo, Yin-Chen He +2
Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on the emergibility problem, i.e. whether a quantum phase or phase transition can emerge in a many-body system. We d…
Emergent anomaly of Fermi surfaces: a simple derivation from Weyl fermions
Ruochen Ma, Chong Wang
The Fermi liquid has an emergent low-energy symmetry that corresponds to charge conservation at each momentum on the Ferm surface. Recently Else, Thorngren and Senthil (ETS) argued…
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…
