Quasiparticle modes across soliton transition with density-dependent gauge field in optical lattices
Poorava Kumar Meena, Kuldeep Suthar
Tunneling of ultracold bosons confined in a one-dimensional optical lattice results in a nontrivial gauge field depending on density-difference between the sites involved. The dens…

Potential-defect-driven collective modes of one-dimensional two-component quantum droplets
Harsimranjit Kaur, Kuldeep Suthar
We examine a one-dimensional binary mixture of ultradilute quantum droplets in the presence of a central potential defect. The properties of the potential strength and the number o…

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…
