Riding the Wave: Polymers in Time-dependent Nonequilibrium Baths
Bhavesh Valecha, Jens-Uwe Sommer, Abhinav Sharma
Directed transport is a characteristic feature of numerous biological systems in response to signals such as nutrient and chemical gradients. These signals often depend on time owi…
Enhanced Efficiency in Shear-Loaded Brownian Gyrators
Iman Abdoli, Abhinav Sharma, Hartmut Löwen
A Brownian gyrator is a system in which a particle experiences thermal noise from two distinct heat baths. This nonequilibrium setup inherently generates a nonzero torque, leading…
Transport of molecules via polymerization in chemical gradients
Shashank Ravichandir, Bhavesh Valecha, Pietro Luigi Muzzeddu +2
The transport of molecules for chemical reactions is critically important in various cellular biological processes. Despite thermal diffusion being prevalent in many biochemical pr…
Combining integral equation closures with force density functional theory for the study of inhomogeneous fluids
S. M. Tschopp, H. Vahid, A. Sharma +1
Classical density functional theory (DFT) is a powerful framework to study inhomogeneous fluids. Its standard form is based on the knowledge of a generating free energy functional.…
Active Transport of Cargo-Carrying and Interconnected Chiral Particles
Bhavesh Valecha, Hossein Vahid, Pietro Luigi Muzzeddu +2
Directed motion up a concentration gradient is crucial for the survival and maintenance of numerous biological systems, such as sperms moving towards an egg during fertilization or…
Migration and separation of polymers in non-uniform active baths
Pietro Luigi Muzzeddu, Andrea Gambassi, Jens-Uwe Sommer +1
Polymer-like structures are ubiquitous in nature and synthetic materials. Their configurational and migration properties are often affected by crowded environments leading to non-t…
Tailoring the escape rate of a Brownian particle by combining a vortex flow with a magnetic field
Iman Abdoli, Hartmut Löwen, Jens-Uwe Sommer +1
The probability per unit time for a thermally activated Brownian particle to escape over a potential well is in general well-described by Kramers theory. Kramers showed that the es…
Escape Dynamics in an Anisotropically Driven Brownian Magneto-System
Iman Abdoli, Jens-Uwe Sommer, Hartmut Löwen +1
Thermally activated escape of a Brownian particle over a potential barrier is well understood within Kramers theory. When subjected to an external magnetic field, the Lorentz force…
Nondiffusive Fluxes in Brownian System with Lorentz Force
Iman Abdoli, Hidde Derk Vuijk, Jens-Uwe Sommer +2
The Fokker-Planck equation provides complete statistical description of a particle undergoing random motion in a solvent. In the presence of Lorentz force due to an external magnet…
