Depolarization of echo chambers by random dynamical nudge
Christopher Brian Currin, Sebastián Vallejo Vera, Ali Khaledi-Nasab
In social networks, users often engage with like-minded peers. This selective exposure to opinions might result in echo chambers, i.e., political fragmentation and social polarizat…
Variability of collective dynamics in random tree networks of strongly-coupled stochastic excitable elements
Ali Khaledi-Nasab, Justus A. Kromer, Lutz Schimansky-Geier +1
We study the collective dynamics of strongly diffusively coupled excitable elements on small random tree networks. Stochastic external inputs are applied to the leaves causing larg…
Emergent stochastic oscillations and signal detection in tree networks of excitable elements
Justus Kromer, Ali Khaledi-Nasab, Lutz Schimansky-Geier +1
We study the stochastic dynamics of strongly-coupled excitable elements on a tree network. The peripheral nodes receive independent random inputs which may induce large spiking eve…
Heavy Tetraquarks in the Diquark-Antidiquark Picture
M. R. Hadizadeh, A. Khaledi-Nasab
The homogeneous Lippmann-Schwinger integral equation is solved in momentum space to calculate the masses of heavy tetraquarks with hidden charm and bottom. The tetraquark bound sta…
Intersubband Electronic Properties of InAs/GaAs Quantum Dot Molecules with Horizontal Spacer
A. Khaledi-Nasab, M. Shahzadeh, H. Amouzegar +1
In this work the intersubband electronic properties of two laterally coupled dome-shaped InAs/GaAs quantum dots were investigated. The envelope functions and eigenenergies were cal…
Size-dependent intersubband optical properties of dome-shaped InAs/GaAs quantum dots with wetting layer
Mohammad Sabaeian, Ali Khaledi-Nasab
In this work, the effect of size and wetting layer on subband electronic envelop functions, eigenenergies, linear and nonlinear absorption coefficients and refractive indices of a…
