Stability and Interaction Dynamics of Solitons in Spatially Engineered High-Order Nonlinear Media
Dao Quang Anh, Bui Duc Tinh, Doan Quang Tri +5
We study spatial solitons and their interaction dynamics in nonlinear optical media with spatially engineered refractive index and competing cubic-quintic (CQ) nonlinear profiles,…
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…
WonDerM: Skin Lesion Classification with Fine-tuned Neural Networks
Yeong Chan Lee, Sang-Hyuk Jung, Hong-Hee Won
As skin cancer is one of the most frequent cancers globally, accurate, non-invasive dermoscopy-based diagnosis becomes essential and promising. A task of the Part 3 of the ISIC Ski…
Vortex creation without stirring in coupled ring resonators with gain and loss
Aleksandr Ramaniuk, Nguyen Viet Hung, Michael Giersig +3
We present study of the dynamics of two ring waveguide structure with space dependent coupling, linear gain and nonlinear absorption - the system that can be implemented in polarit…
Spatial control of the competition between self-focusing and self-defocusing nonlinearities in one- and two-dimensional systems
Nguyen Viet Hung, Marek Trippenbach, Eryk Infeld +1
We introduce a system with competing self-focusing (SF) and self-defocusing (SDF) terms, which have the same scaling dimension. In the one-dimensional (1D) system, this setting is…
Symmetry breaking in the collisions of double channel BEC solitons
Nguyen Viet Hung, Pawel Zin, Eryk Infeld
We investigate an attractive Bose-Einstein condensate in two coupled one dimensional channels. In this system a stable double channel soliton can be formed. It is symmetric for sma…
Symmetric and asymmetric solitons trapped in H-shaped potentials
Nguyen Viet Hung, Marek Trippenbach, Boris A. Malomed
We report results of numerical and analytical studies of the spontaneous symmetry breaking in solitons, both two- and one-dimensional, which are trapped in H-shaped potential profi…
Two - dimensional solitons in media with the stripe - shaped nonlinearity modulation
Nguyen Viet Hung, Pawe\lZiń, Marek Trippenbach +1
We introduce a model of media with the cubic attractive nonlinearity concentrated along a single or double stripe in the two-dimensional (2D) plane. The model can be realized in te…
Matter wave soliton collisions in the quasi one dimensional potential
Nguyen Viet Hung, Michal Matuszewski, Marek Trippenbach
We consider soliton solutions of a two-dimensional nonlinear system with the self-focusing nonlinearity and a quasi-1D confining potential, taking harmonic potential as an example.…
