Theory of universal differential conductance of magnetic Weyl type -II junctions
M. Maiti, J. Smotlacha
We study the transport properties of junctions of normal and superconducting Weyl semi-metal with tilted dispersion, in the presence of magnetization induced by magnetic strips. Th…
A bulk-boundary correspondence for dynamical phase transitions in one-dimensional topological insulators and superconductors
N. Sedlmayr, P. Jäger, M. Maiti +1
We study the Loschmidt echo for quenches in open one-dimensional lattice models with symmetry protected topological phases. For quenches where dynamical quantum phase transitions d…
Magnetization induced dynamics of a Josephson junction coupled to a nanomagnet
Roopayan Ghosh, Moitri Maiti, Yury M. Shukrinov +1
We study the superconducting current of a Josephson junction (JJ) coupled to an external nanomagnet driven by a time dependent magnetic field both without and in the presence of an…
Entanglement and Majorana edge states in the Kitaev model
Saptarshi Mandal, Moitri Maiti, Vipin Kerala Varma
We investigate the von Neumann entanglement entropy and Schmidt gap in the ground state of the Kitaev model on the honeycomb lattice for square and cylindrical subsystems. We find…
Josephson junction detectors for Majorana modes and Dirac fermions
M. Maiti, K. M. Kulikov, K. Sengupta +1
We demonstrate that the current-voltage (I-V) characteristics of resistively and capacitively shunted Josephson junctions (RCSJs) hosting localized subgap Majorana states provides…
Boundary Fidelity and Entanglement in the symmetry protected topological phase of the SSH model
J. Sirker, M. Maiti, N. P. Konstantinidis +1
We present a detailed study of the fidelity, the entanglement entropy, and the entanglement spectrum, for a dimerized chain of spinless fermions---a simplified Su-Schrieffer-Heeger…
Graphene: Junctions and STM Spectra
M. Maiti, K. Saha, K. Sengupta
In this review we focus on the effect of the Dirac nature of graphene quasiparticles on two separate aspects. The first of these involves transport across superconducting graphene…
A semi-classical analysis of Dirac fermions in 2+1 dimensions
Moitri Maiti, R. Shankar
We investigate the semiclassical dynamics of massless Dirac fermions in 2+1 dimensions in the presence of external electromagnetic fields. By generalizing the matrices to the s…
Theory of tunneling conductance of graphene NIS junctions
Subhro Bhattacharjee, Moitri Maiti, K. Sengupta
We calculate the tunneling conductance of a graphene normal metal-insulator-superconductor (NIS) junction with a barrier of thickness and with an arbitrary voltage applie…
Josephson effect in graphene SBS junctions
Moitri Maiti, K. Sengupta
We study Josephson effect in graphene superconductor- barrier- superconductor junctions with short and wide barriers of thickness and width , which can be created by applyin…
Spin-Hall effect in triplet chiral superconductors and graphene
K. Sengupta, Rahul Roy, Moitri Maiti
We study spin-Hall effects in time-reversal symmetry (TRS) broken systems such as triplet chiral superconductors and TRS preserved ones such as graphene. For chiral triplet superco…
