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…
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…
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…
Hydrogen induces chiral conduction channels in the topological magnet
Afrin N. Tamanna, Ayesha Lakra, Xiaxin Ding +7
Chirality, a characteristic handedness that distinguishes 'left' from 'right', cuts widely across all of nature, from the structure of DNA to opposite chirality of particle…
Anisotropic positive linear and sub-linear magnetoresistivity in the cubic type-II Dirac metal PdIn
Aikaterini Flessa Savvidou, Andrzej Ptok, G. Sharma +6
We report a transport study on PdIn which displays multiple Dirac type-II nodes in its electronic dispersion. PdIn is characterized by low residual resistivities an…
Anomalous transport in Kane fermions
Karun Gadge, Sumanta Tewari, Gargee Sharma
Kane fermions are characterized by a linear Dirac cone intersecting with a flat band, resembling a pseudo-spin-1 Dirac semimetal. Similar to relativistic Dirac fermions, Kane fermi…
Chiral anomaly and longitudinal magnetotransport in type-II Weyl semimetals
Gargee Sharma, Pallab Goswami, Sumanta Tewari
In the presence of parallel electric and magnetic fields, the violation of separate number conservation laws for the three dimensional left and right handed Weyl fermions is known…
Conformal symmetry wormholes and the null energy condition
Peter K. F. Kuhfittig
In this paper we seek a relationship between the assumption of conformal symmetry and the exotic matter needed to hold a wormhole open. By starting with a Morris-Thorne wormhole ha…
Optical gyrotropy as a test for dynamic chiral magnetic effect of Weyl semimetals
Pallab Goswami, Gargee Sharma, Sumanta Tewari
Recent angle resolved photoemission spectroscopy measurements have identified an inversion symmetry breaking Weyl semimetal phase in TaAs and NbAs. In an inversion symmetry breakin…
