Effective Diffusion and transport coherence in presence of inhomogeneous temeprature: Piecewise linear potential
Ronald Benjamin
We compute the effective diffusion coefficient of a Brownian particle in a piece-wise linear periodic potential and subject of spatially inhomogeneous temperature, otherwise known…
Effect of roughness on the transport of an overdamped Brownian particle
Prathyusha S Nair, Ronald Benjamin
We study the transport of an overdamped Brownian particle in a tilted rough potential driven by a gaussian white noise.We conisder various forms of rough potentials to analyse the…
Free energy cost of forming an interface between a crystal and its frozen version
Ronald Benjamin, Jürgen Horbach
Using a thermodynamic integration scheme, we compute the free energy cost per unit area, , of forming an interface between a crystal and a frozen structured wall, formed by part…
Crystal growth kinetics in Lennard-Jones and Weeks-Chandler-Andersen systems along the solid-liquid coexistence line
Ronald Benjamin, Jürgen Horbach
Kinetics of crystal-growth is investigated along the solid-liquid coexistence line for the (100), (110) and (111) orientations of the Lennard-Jones and Weeks-Chandler-Andersen fcc…
Excess free energy of supercooled liquids at disordered walls
Ronald Benjamin, Jürgen Horbach
Using a novel thermodynamic integration scheme, we compute the excess free energy, , of a glass-forming, binary Lennard-Jones liquid in contact with a frozen amorphous wall, for…
Lennard-Jones systems near solid walls: Computing interfacial free energies from molecular simulation methods
Ronald Benjamin, Jürgen Horbach
Different computational techniques in combination with molecular dynamics computer simulation are used to to determine the wall-liquid and the wall-crystal interfacial free energie…
Wall-liquid and wall-crystal interfacial free energies via thermodynamic integration: A molecular dynamics simulation study
Ronald Benjamin, Jürgen Horbach
A method is proposed to compute the interfacial free energy of a Lennard-Jones system in contact with a structured wall by molecular dynamics simulation. Both the bulk liquid and b…
Stochastic energetics of a Brownian motor and refrigerator driven by non-uniform temperature
Ronald Benjamin
The energetics of a Brownian heat engine and heat pump driven by position dependent temperature, known as the Büttiker-Landauer heat engine and heat pump, is investigated by numeri…
Inertial effects in B{ü}ttiker-Landauer Motor and Refrigerator at the Overdamped Limit
Ronald Benjamin, Ryoichi Kawai
We investigate the energetics of a Brownian motor driven by position dependent temperature, commonly known as the B{ü}ttiker-Landauer motor. Overdamped models (M=0) predict that th…
