Efficiency of isothermal molecular machines at maximum power
Christian Van den Broeck, Niraj Kumar, Katja Lindenberg
We derive upper and lower bounds for the efficiency of an isothermal molecular machine operating at maximum power. The upper bound is reached when the activated state is close to t…
Stochastically driven single level quantum dot: a nano-scale finite-time thermodynamic machine and its various operational modes
Massimiliano Esposito, Niraj Kumar, Katja Lindenberg +1
We describe a single-level quantum dot in contact with two leads as a nanoscale finite-time thermodynamic machine. The dot is driven by an external stochastic force that switches i…
Thermodynamics of a stochastic twin elevator
Niraj Kumar, Christian Van den Broeck, Massimiliano Esposito +1
We study the non-equilibrium thermodynamics of a single particle with two available energy levels, in contact with a classical (Maxwell-Boltzmann) or quantum (Bose-Einstein) heat b…
Front propagation in A2A, A3A process in 1d: velocity, diffusion and velocity correlations
Niraj Kumar, Goutam Tripathy
We study front propagation in the reaction diffusion process on a one dimensional (1d) lattice with hard core interaction between the…
Two site self consistent method for front propagation in reaction-diffusion system
Niraj Kumar, Goutam Tripathy
We study front propagation in the reaction diffusion process on one dimensional lattice with hard core interaction between the particles. We propose a two site…
Velocity of front propagation in the epidemic model
Niraj Kumar, Goutam Tripathy
We study front propagation in the irreversible epidemic model in one dimension. Here, we allow the particles and to diffuse with rates and , which, i…
