PT-symmetry breaking with divergent potentials: lattice and continuum cases
Yogesh N. Joglekar, Derek D. Scott, Avadh Saxena
We investigate the parity- and time-reversal ()-symmetry breaking in lattice models in the presence of long-ranged, non-hermitian, -symmetric potentials…
PT-restoration via increased loss-gain in PT-symmetric Aubry-Andre model
Charles Liang, Derek D. Scott, Yogesh N. Joglekar
In systems with ``balanced loss and gain'', the PT-symmetry is broken by increasing the non-hermiticity or the loss-gain strength. We show that finite lattices with oscillatory, PT…
Optical waveguide arrays: quantum effects and PT symmetry breaking
Yogesh N. Joglekar, Clinton Thompson, Derek D. Scott +1
Over the last two decades, advances in fabrication have led to significant progress in creating patterned heterostructures that support either carriers, such as electrons or holes,…
PT-symmetry breaking and maximal chirality in a nonuniform PT-symmetric ring
Derek D. Scott, Yogesh N. Joglekar
We study the properties of an N-site tight-binding ring with parity and time-reversal (PT) symmetric, Hermitian, site-dependent tunneling and a pair of non-Hermitian, PT-symmetric,…
PT-symmetry breaking and universal chirality in a PT-symmetric ring
Derek D. Scott, Yogesh N. Joglekar
We investigate the properties of an -site tight-binding lattice with periodic boundary condition (PBC) in the presence of a pair of gain and loss impurities , and two tu…
Degrees and signatures of broken PT-symmetry in (non-uniform) lattices
Derek D. Scott, Yogesh N. Joglekar
We investigate the robustness of parity- and time-reversal ($\mP\mT$) symmetric phase in an -site lattice with position-dependent, parity-symmetric hopping function and a pair o…
Robust and fragile PT-symmetric phases in a tight-binding chain
Yogesh N. Joglekar, Derek Scott, Mark Babbey +1
We study the phase-diagram of a parity and time-reversal (PT) symmetric tight-binding chain with sites and hopping energy , in the presence of two impurities with imaginary…
