Current switching behavior mediated via hinge modes in higher-order topological phases using altermagnets
Minakshi Subhadarshini, Amartya Pal, Arijit Saha
We propose a theoretical framework to engineer hybrid-order and higher-order topological phases in three-dimensional topological insulators by coupling to -wave altermagnets (AM…
Topological superconductivity and superconducting diode effect mediated via unconventional magnet and Ising spin-orbit coupling
Amartya Pal, Debashish Mondal, Tanay Nag +1
We propose a theoretical framework in which a one-dimensional (1D) tight-binding model incorporating unconventional magnetic order together with Rashba and Ising spin-orbit couplin…
Proximity-induced superconductivity and emerging topological phases in altermagnet-based heterostructures
Ohidul Alam, Amartya Pal, Paramita Dutta +1
We present a theoretical framework for investigating superconducting proximity effect in altermagnet (AM)-superconductor (SC) heterostructures. In general, AMs, characterized by va…
Spin polarization and diode effect in thermoelectric current through altermagnet-based superconductor heterostructures
Debika Debnath, Arijit Saha, Paramita Dutta
The recent advent of a new class of magnetic material named as {\it altermagnet} (AM), characterized by a combination of momentum-dependent spin splitting with zero net magnetizati…
Non-Hermitian band topology in twisted bilayer graphene aligned with hexagonal boron nitride
Kamalesh Bera, Debasish Mondal, Arijit Saha +1
Utilizing the established Bistritzer-MacDonald model for twisted bilayer graphene (tBLG), we theoretically investigate the non-Hermitian (NH) topological properties of this in the…
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…
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…
