On the Sum of Inverse Gamma RVs and its Application to Wireless Communications Networks
Petros S. Bithas, Liang Yang, Qiuming Zhu +2
Investigating the statistics of the sum of random variables (RVs) is fundamental in wireless communication systems, as it can be used to accurately estimate their performance. In t…
Non-autonomous bright-dark solitons and Rabi oscillations in multi-component Bose-Einstein condensates
T. Kanna, R. Babu Mareeswaran, F. Tsitoura +2
We study the dynamics of non-autonomous bright-dark matter-wave solitons in two- and three- component Bose-Einstein condensates. Our setting includes a time-dependent parabolic pot…
Control of the symmetry breaking in double-well potentials by the resonant nonlinearity management
H. E. Nistazakis, B. A. Malomed, P. G. Kevrekidis +1
We introduce a one-dimensional model of Bose-Einstein condensates (BECs), combining the double-well potential, which is a well-known setting for the onset of spontaneous-symmetry-b…
Matter-wave dark solitons: stochastic vs. analytical results
S. P. Cockburn, H. E. Nistazakis, T. P. Horikis +3
The dynamics of dark matter-wave solitons in elongated atomic condensates are discussed at finite temperatures. Simulations with the stochastic Gross-Pitaevskii equation reveal a n…
Dynamical oscillations in nonlinear optical media
Theodoros P. Horikis, Hector E. Nistazakis
The spatial dynamics of pulses in Kerr media with parabolic index profile are examined. It is found that when diffraction and graded-index have opposite signs propagating pulses ex…
Soliton Dynamics in Linearly Coupled Discrete Nonlinear Schrödinger Equations
A. Trombettoni, H. E. Nistazakis, Z. Rapti +2
We study soliton dynamics in a system of two linearly coupled discrete nonlinear Schrödinger equations, which describe the dynamics of a two-component Bose gas, coupled by an elect…
