Phase-Shifted Planar Hall and Magnetoresistive Responses in Weyl Semimetals
Sandip Bera, Sudhansu S. Mandal
The planar Hall resistivity and magnetoresistivity of Weyl semimetals are conventionally expected to exhibit and angular dependences, respectively, where …
Probing Axion Dark Matter via the Chiral Magnetic Effect in Zero-Bias Weyl Semimetals
Debajit Bose, Prataya Chandra, Sudhansu S. Mandal +1
Sub-eV axion dark matter behaves as a coherent classical field that can induce macroscopic current in quantum materials. We explore the possibility of axion detection via the chira…
Trimerized Spin- Chain: Emergent Low-Energy Hamiltonian, Higher-Energy Excitations, and Magnetic and Thermodynamic Responses
Snehasish Sen, Sudhansu S. Mandal
We investigate a spin-1/2 antiferromagnetic chain with trimerized exchange couplings relevant to NaCuGeO. We show that the low-energy Hilbert space maps onto an…
Fermionic Band Dispersions and an Evidence of Cooperon Excitations in a Spin- Trimer Chain
P. Srikanth Patnaik, Snehasish Sen, A. K. Bera +3
We obtain the solution of the Hamiltonian of an antiferromagnetically coupled spin- trimer chain in terms of three bands that host three different species of fermions. While t…
Inhomogeneous phase stiffness in two-dimensional -wave disordered superconductors
Sudipta Biswas, A. Taraphder, Sudhansu S. Mandal
We investigate the effect of white-noise disorder on the local phase stiffness and thermodynamic properties of a two-dimensional -wave superconductor. Starting from a local attr…
