Superconducting order parameter in aperiodic binary systems
Sougata Biswas, Debika Debnath, Paramita Dutta
Recent discovery of the superconducting ground state in systems lacking perfect periodicity but with long-range ordering has opened up an exciting new avenue for superconductivity…
Dive deeper with SUBMARINE: SUB-Mev dArk matter diRect detectIon using bilayer grapheNE
Rinchen Sherpa, Anuvab Sarkar, Tarak Nath Maity +3
Novel target materials with anisotropic response will play a key role in detecting low-mass dark matter in upcoming experiments. Bilayer graphene is one such material that has been…
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…
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…
Altermagnetic phases and phase transitions in Lieb- Hubbard model
Sougata Biswas, Achintyaa, Paramita Dutta
The emergence of altermagnetism, the collinear magnetic phase characterized by momentum-dependent spin-split bands but zero net magnetization, has fundamentally reshaped the classi…
