Quantum tomography of a third-order exceptional point in a dissipative trapped ion
Y. -Y. Chen, K. Li, L. Zhang +9
The requirement for Hermiticity in quantum mechanics ensures the reality of energies, while the parity-time symmetry offers an alternative route to achieve this goal. Interestingly…
Nonlinear study of local ballooning mode near the separatrix
T. F. Tang, X. Q. Xu, K. Li +6
Small edge-localized-mode (ELM), similar to the quasi-continuous exhaust (QCE), has been achieved by increasing the density at the separatrix. Starting from the Type-I ELM experime…
PT-symmetric Double Well Potentials Revisited: Bifurcations, Stability and Dynamics
A. S. Rodrigues, K. Li, V. Achilleos +3
In this work we analyze PT-symmetric double-well potentials based on a two-mode picture. We reduce the problem into a PT-symmetric dimer and illustrate that the latter has effectiv…
Intrinsic localized modes in coupled DNLS equations from the anti-continuum limit
K. Li, P. G. Kevrekidis, H. Susanto +1
In the present work, we generalize earlier considerations for intrinsic localized modes consisting of a few excited sites, as developed in the one-component discrete nonlinear Schr…
