Emergent superconducting phases in unconventional -wave magnets: Topological superconductivity, Bogoliubov Fermi surfaces and superconducting diode effect
Amartya Pal, Paramita Dutta, Arijit Saha
The recent discovery of unconventional momentum-dependent magnetic orders has expanded the landscape of magnetism beyond conventional ferromagnetism and antiferromagnetism. Among t…
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…
Josephson current signature of Floquet Majorana and topological accidental zero modes in altermagnet heterostructures
Amartya Pal, Debashish Mondal, Tanay Nag +1
We theoretically investigate the generation and Josephson current signatures of Floquet Majorana end modes (FMEMs) in a periodically driven altermagnet (AM) heterostructure. Consid…
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…
Identifying Bogoliubov Fermi surfaces via thermoelectric response in a -wave superconductor heterostructure
Amartya Pal, Paramita Dutta, Arijit Saha
We theoretically investigate the thermoelectric response of Bogoliubov Fermi surfaces (BFSs) generated in a two dimensional unconventional -wave superconductor subjected to an e…
Distinguishing between topological Majorana and trivial zero modes via transport and shot noise study in an altermagnet heterostructure
Debashish Mondal, Amartya Pal, Arijit Saha +1
We theoretically investigate the transport and shot noise properties of a one-dimensional semiconducting nanowire with Rashba spin-orbit coupling~(SOC) placed in closed proximity t…
