Collective modes of two-species Bose-Einstein condensates in a Josephson junction barrier
Harsimranjit Kaur, Kuldeep Suthar
The ultracold atoms are an ideal platform to implement atomtronics and Josephson junctions analogous to superconducting circuits. The collective modes of a Bose gas split by a pote…

Boundary-driven many-body phase transitions in a non-Hermitian disordered fermionic chain
Kuldeep Suthar
The non-Hermitian systems exhibit extreme sensitivity to the boundary conditions. The change in the eigenspectrum with tunning boundary parameter is intimately connected to the non…
