Chiral Anomaly Induced Transverse Planar Transport Phenomena in Three Dimensional Spin-Orbit Coupled Metals
Rishi G. Gopalakrishnan, Binayyak B. Roy, Gargee Sharma +1
We investigate linear and nonlinear transverse planar transport phenomena (viz. linear and nonlinear Hall and Nernst coefficients) induced by chiral anomaly in three-dimensional sp…
Strain-controlled crossover between Majorana and Andreev bound states in disordered superconductor-semiconductor heterostructures
Shubhanshu Karoliya, Ekta, Gargee Sharma
The unambiguous identification of topological Majorana-bound states (MBSs) in superconducting hybrid systems is hindered by trivial low-energy excitations, especially partially sep…
Localization and universality of three-dimensional pseudospin- fermions
Arpan Gupta, Gargee Sharma
Quantum interference of electrons in disordered conductors is a sensitive probe of the internal structure of quasiparticles, revealing universal signatures of symmetry through weak…
Majorana modes in graphene strips: polarization, wavefunctions, disorder, and Andreev states
Shubhanshu Karoliya, Sumanta Tewari, Gargee Sharma
Topologically protected Majorana zero modes (MZMs) have attracted intense interest due to their potential application in fault-tolerant quantum computation (TQC). Graphene nanoribb…
Majorana polarization in disordered heterostructures
Shubhanshu Karoliya, Sumanta Tewari, Gargee Sharma
Recent studies propose Majorana polarization (MP) as a tool for identifying topological Majorana bound states (MBS). We analyze MP in two systems: a one-dimensional (1d) semiconduc…
