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…
Unquantized anomalies in topological semimetals
Lei Gioia, Chong Wang, A. A. Burkov
Topological semimetals are a new class of metallic materials, which exist at band fillings that ordinarily correspond to insulators or compensated accidental semimetals with zero L…
Chiral Anomaly in Interacting Condensed Matter Systems
Colin Rylands, Alireza Parhizkar, Anton A. Burkov +1
The chiral anomaly is a fundamental quantum mechanical phenomenon which is of great importance to both particle physics and condensed matter physics alike. In the context of QED it…
Charge density waves in Weyl semimetals
Dan Sehayek, Manisha Thakurathi, A. A. Burkov
We present a theory of charge density wave (CDW) states in Weyl semimetals and their interplay with the chiral anomaly. In particular, we demonstrate a special nature of the shorte…
