Cascade of transitions in molecular information theory
Suman G. Das, Madan Rao, Garud Iyengar
Biological organisms are open, adaptve systems that can respond to changes in environment in specific ways. Adaptation and response can be posed as an optimization problem, with a…
A universal lower bound on the free energy cost of molecular measurements
Suman G. Das, Garud Iyengar, Madan Rao
The living cell uses a variety of molecular receptors to read and process chemical signals that vary in space and time. We model the dynamics of such molecular level measurements a…
Role of conserved quantities in normal heat transport in one dimenison
Suman G. Das, Abhishek Dhar
Although one-dimensional systems that exhibit translational symmetry are generally believed to exhibit anomalous heat transport, previous work has shown that the model of coupled r…
Numerical test of hydrodynamic fluctuation theory in the Fermi-Pasta-Ulam chain
Suman G. Das, Abhishek Dhar, Keiji Saito +2
Recent work has developed a nonlinear hydrodynamic fluctuation theory for a chain of coupled anharmonic oscillators governing the conserved fields, namely stretch, momentum, and en…
Heat conduction in the α-β-Fermi-Pasta-Ulam chain
Suman G. Das, Abhishek Dhar, Onuttom Narayan
Recent simulation results on heat conduction in a one-dimensional chain with an asymmetric inter-particle interaction potential and no onsite potential found non-anomalous heat tra…
Landauer formula for phonon heat conduction: relation between energy transmittance and transmission coefficient
Suman G. Das, Abhishek Dhar
The heat current across a quantum harmonic system connected to reservoirs at different temperatures is given by the Landauer formula, in terms of an integral over phonon frequencie…
