Universal magnetotunnel conductance at a Weyl semimetal-layered Chern insulator junction
Nirnoy Basak, Sumathi Rao, Faruk Abdulla
We investigate electronic transport across a junction between a Weyl semimetal (WSM) and a layered Chern insulator (LCI) in the presence of a magnetic field perpendicular to the in…
Breakdown of chiral anomaly and emergent phases in Weyl semimetals under orbital magnetic fields
Faruk Abdulla, Anna Keselman, Daniel Podolsky
An external orbital magnetic field applied perpendicular to the separation vector of a pair of Weyl points can couple them and induce a gap in the electronic spectrum. In this work…
Emergent topology in thin films of nodal line semimetals
Faruk Abdulla
We investigate finite-size topological phases in thin films of nodal line semimetals (co-dimension 2) in three dimensions. By analyzing the hybridization of drumhead surface states…
Magneto tunnel conductance across twisted Weyl semimetal junctions
Nirnoy Basak, Sumathi Rao, Faruk Abdulla
We investigate magnetotransport across an interface between two Weyl semimetals (finite in both directions) whose Weyl nodes project onto two different surfaces which are twisted w…
Pairwise annihilation of Weyl nodes induced by magnetic fields in the Hofstadter regime
Faruk Abdulla
Weyl semimetal, which does not require any symmetry except translation for protection, is a robust gapless state of quantum matters in three dimensions. When translation symmetry i…
Protected Weyl semimetals within 2D chiral classes
Faruk Abdulla
Weyl semimetals in three dimensions can exist independently of any symmetry apart from translations. In contrast, in two dimensions, Weyl semimetals require additional symmetries,…
Stable nodal line semimetals in the chiral classes in three dimensions
Faruk Abdulla, Ganpathy Murthy, Ankur Das
It has been realized over the past two decades that topological nontriviality can be present not only in insulators but also in gapless semimetals, the most prominent example being…
Topological nodal line semimetals with chiral symmetry
Faruk Abdulla, Ganpathy Murthy, Ankur Das
Topological semimetals in three dimensions display band-touchings at points (Weyl or Dirac semimetals) or nodal lines in the Brillouin zone. Weyl semimetals can occur with internal…
Time-reversal-broken Weyl semimetal in the Hofstadter regime
Faruk Abdulla, Ankur Das, Sumathi Rao +1
We study the phase diagram for a lattice model of a time-reversal-broken three-dimensional Weyl semimetal (WSM) in an orbital magnetic field with a flux of per unit cell…
Fermi arc reconstruction at the interface of twisted Weyl semimetals
Faruk Abdulla, Sumathi Rao, Ganpathy Murthy
Three-dimensional Weyl semimetals have pairs of topologically protected Weyl nodes, whose projections onto the surface Brillouin zone are the end points of zero energy surface stat…
Curvature function renormalisation, topological phase transitions and multicriticality
Faruk Abdulla, Priyanka Mohan, Sumathi Rao
A recently proposed curvature renormalization group scheme for topological phase transitions defines a generic `curvature function' as a function of the parameters of the theory an…
