Non-Hermiticity induced thermal entanglement phase transition
Bikashkali Midya
Theoretical analysis of a prototypical two-qubit effective non-Hermitian system characterized by asymmetric Heisenberg interactions in the absence of external magnetic fields…
Topological phase transition in fluctuating imaginary gauge fields
Bikashkali Midya
We investigate the exact solvability and point-gap topological phase transitions in non-Hermitian lattice models. These models incorporate site-dependent nonreciprocal hoppings $J…
Gain-loss-induced non-Abelian Bloch braids
B. Midya
Onsite gain-loss-induced topological braiding principle of non-Hermitian energy bands is theoretically formulated in multiband lattice models with Hermitian hopping amplitudes. Bra…
Topological directed amplification
Bikashkali Midya
A phenomenon of topological directed amplification of certain initial perturbations is revealed theoretically to emerge in a class of asymptotically stable skin-effect lattices des…
Non-Hermitian tuned topological band gap
Bikashkali Midya
Externally controllable band gap properties of a material is crucial in designing optoelectronic devices with desirable properties on-demand. Here, a possibility of single paramete…
Non-Hermitian heterostructure for two-parameter sensing
Jieun Yim, Han Zhao, Bikashkali Midya +1
Non-Hermitian systems at the exceptional point (EP) degeneracy are demonstrated to be highly sensitive to environmental perturbation. Here, we propose and theoretically investigate…
