Re-entrant parity-time phase transitions in locally coupled ring resonators
Nguyen Duc Anh Quan, Le Xuan The Tai, Doan Quang Tri +3
We investigate two parity-time-symmetric ring resonators coupled over a finite angular region described by a super-Gaussian profile. In the linear regime, analytical spectra are ob…

Fluctuation effect on Nonlinear Transport and Nernst-Ettingshausen Response in Two-Dimensional Superconductors under electric and magnetic field
Tran Ky Vi, Bui Duc Tinh, Ngo Quang Duc +4
In this paper, we present a unified theoretical study of fluctuation-dominated transport and transverse thermoelectric response in two-dimensional superconducting films subjected t…

Analysis of High-Contrast All-Optical Dual Wavelength Switching in Asymmetric Dual-Core Fibers
Le Xuan The Tai, Mattia Longobucco, Nguyen Viet Hung +8
We systematically present experimental and theoretical results for the dual-wavelength switching of 1560 nm, 75 fs signal pulses (SPs) driven by 1030 nm, 270 fs control pulses (CPs…
