Higher order exchange driven noncoplanar magnetic state and large anomalous Hall effects in electron doped kagome magnet MnSn
Charanpreet Singh, Sk Jamaluddin, Ashis K. Nandy +3
Owing to the geometrical frustration, MnSn exhibits a 120 in-plane triangular antiferromagnetic (AFM) order with a large anomalous Hall effect (AHE). Here, we presen…
Observation of anisotropic Dirac cones in the topological material Ti2Te2P
Gyanendra Dhakal, Firoza Kabir, Ashis K. Nandy +12
Anisotropic bulk Dirac (or Weyl) cones in three dimensional systems have recently gained intense research interest as they are examples of materials with tilted Dirac (or Weyl) con…
Tailoring phase transition from topological superconductor to trivial superconductor induced by magnetic textures of a spin-chain on a -wave superconductor
Pritam Chatterjee, Saurabh Pradhan, Ashis K. Nandy +1
We theoretically investigate the phase transition from a non-trivial topological -wave superconductor to a trivial -wave like superconducting phase through a gapless phase, d…
Vector Chirality Driven Topological Phase Transition and the Associated Anomalous Hall Conductivity Tuning in a Non-Collinear Antiferromagnet
Subhadip Pradhan, Kartik Samanta, Kush Saha +1
Based on the first-principles electronic structure calculations and subsequent symmetry adapted effective low-energy theory, we show the switching of the vector chir…
Defect Modulated Band Modification in Ion Implanted MgO Crystal: Experimental and Ab Initio Calculations
Sourav Bhakta, Subhadip Pradhan, Ashis K. Nandy +1
Defects creation and annihilation is a fundamental concept in device fabrication. This report studies the optical bandgap modification in MgO by MeV Ni ion irradiation-induced defe…
