Topological semimetals are intensively studied in recent years. Besides the well known Weyl and Dirac semimetals, some materials posses nodes with linear crossing of multiple bands. Low energy excitations around these nodes are called multifold fermi

One of the fundamental facts of condensed matter physics is that sufficient amount of disorder always turns a Fermi liquid metal into an Anderson insulator: a compressible, but non-conducting phase of matter. Recently, topological semimetals have eme

We present a theory for thin films of the Dirac semimetal Cd$_3$As$_2$ in the presence of magnetic fields. We show that, above a critical thickness, specific subbands $n$ of thin film Cd$_3$As$_2$ are in a quantum spin Hall insulator regime and study

Weyl fermions possess the property of spin-momentum locking: the expectation value of the spin is parallel or antiparallel to the momentum at any given point in the Brillouin zone in the vicinity of a Weyl node. This is a direct consequence of the fa

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 translational symmetries, which all protect the gapless nodes in a weakly int

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 simulations to demonstrate the existence of a quantum phase transitio

We discuss the modified quantum electrodynamics from a time-reversal-breaking Weyl semimetal coupled with a $U(1)$ gauge (electromagnetic) field. A key role is played by the soft dispersion of the photons in a particular direction, say $\hat{z}$, due
