Confinement-Induced Optimization of Fluctuation-Induced Forces in Active Fluids
Reza Shaebani, Hashem Fatemi, Hamidreza Khalilian +1
Active matter generates nonequilibrium fluctuations that mediate effective interactions between immersed objects. While fluctuation-induced (FI) forces in active fluids depend on a…
Structural dynamics and optimal transport of an active polymer
Hamidreza Khalilian, Fernando Peruani, Jalal Sarabadani
We study the spontaneous configuration transitions of an active semi-flexible polymer between {\it spiral} and {\it non-spiral} states, and show that the configuration dynamics is…
Optimal chirality enhances long-range fluctuation-induced interactions in active fluids
Hashem Fatemi, Hamidreza Khalilian, Jalal Sarabadani +1
Understanding interactions between chiral active particles -- self-propelling and self-rotating entities -- is crucial for uncovering how chiral active matter self-organizes into d…
Translocation of an Active Polymer into a Circular Cavity
Amir Rezaie-Dereshgi, Hamidreza Khalilian, Jalal Sarabadani
Translocation dynamics of an active semi-flexible polymer through a nano-pore into a rigid two dimensional circular cavity, and the polymer packing dynamics have been studied by us…
Polymer translocation in an environment of active rods
Hamidreza Khalilian, Jalal Sarabadani, Tapio Ala-Nissila
We consider the dynamics of a translocation process of a flexible linear polymer through a nanopore into an environment of active rods in the {\it trans} side. Using Langevin dynam…
Polymer translocation through nanopore assisted by an environment of active rods
Hamidreza Khalilian, Jalal Sarabadani, Tapio Ala-Nissila
We use a combination of computer simulations and iso-flux tension propagation (IFTP) theory to investigate translocation dynamics of a flexible linear polymer through a nanopore in…
Interplay of quenching temperature and drift in Brownian dynamics
Hamid Khalilian, Mehrana R. Nejad, Ali G. Moghaddam +1
We investigate the non-equilibrium evolution of ideal Brownian particles confined between two walls, following simultaneous quenches of the temperature and a constant external forc…
Obstruction enhances the diffusivity of self-propelled rod-like particles
Hamidreza Khalilian, Hossein Fazli
Diffusion of self-propelled particles in the presence of randomly distributed obstacles in three dimensions is studied using molecular dynamics simulations. It is found that depend…
Directed translocation of a flexible polymer through a cone-shaped channel
Narges Nikoofard, Hamidreza Khalilian, Hossein Fazli
Entropy-driven directed translocation of a flexible polymer through a cone-shaped channel is studied theoretically and using computer simulation. For a given length of the channel,…
