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…

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…

Topological phase transition and its stability against an applied magnetic field in a class of low dimensional decorated lattices
Sougata Biswas
The possibility of topological phase transition with or without a magnetic flux trapped in the cells of a class of decorated lattices is explored in details.Using a tight binding H…
