A quantum phase transition in the one-dimensional water chain
Tobias Serwatka, Roger G. Melko, Anton Burkov +1
The concept of quantum phase transitions (QPT) plays a central role in the description of condensed matter systems. In this contribution, we perform high-quality wavefunction-based…
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…
Topological properties of Dirac and Weyl semimetals
A. A. Burkov
This chapter describes topological (Dirac and Weyl) semimetals from the viewpoint of their observable electromagnetic response. We argue that this response may be represented by to…
Twisted bilayers of thin film magnetic topological insulators
Gaurav Chaudhary, Anton A. Burkov, Olle G. Heinonen
Twisted bilayer graphene (TBG) near "magic angles" has emerged as a rich platform for strongly correlated states of two-dimensional Dirac semimetals. Here we show that twisted bila…
