Emergent Nodal Spheres and Weyl Fermions via Spin-Texture Coupled to Thin Film Orbital Dirac Semimetals
Pritam Chatterjee, Anirudha Menon
We consider the minimal coupling of a thin film Dirac semimetal Hamiltonian to a generic spin-texture. A simple unitary transformation gauges away the spatial dependence in the exc…
Thermoelectric properties of magic angle twisted bilayer graphene-superconductor hetero-junction: effect of valley polarization and trigonal warping
Kamalesh Bera, Pritam Chatterjee, Priyanka Mohan +1
We theoretically investigate the thermoelectric properties (electronic contribution) of a normal-superconductor (NS) hybrid junction, where the normal region consists of magic-angl…
Identifying Majorana edge and end modes in a Josephson junction of a -wave superconductor with a magnetic barrier
Minakshi Subhadarshini, Amartya Pal, Pritam Chatterjee +1
We propose a theoretical model describing a Josephson junction featuring a magnetically textured barrier within two-dimensional (2D) -wave superconductor, considering both $p_x…
Interplay between altermagnetism and topological superconductivity on an unconventional superconducting platform
Pritam Chatterjee, Vladimir JuriÄiÄ
We propose a theoretical model to investigate the interplay between altermagnetism and -wave superconductivity, with a particular focus on topological phase transitions in a two…
