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…

Field-free Josephson diode effect in interacting chiral quantum dot junctions
Debika Debnath, Paramita Dutta
We investigate chiral quantum dot (QD)-based Josephson junction and show the correlation-induced Josephson diode effect (JDE) in it. The presence of electron-electron interaction s…
