Mathematical analysis and numerical methods for the computation of transport coefficients in molecular dynamics
Noe Blassel, Louis Carillo, Shiva Darshan +7
We review various numerical approaches to compute transport coefficients in molecular dynamics. These approaches can be broadly classified into three groups: (i) nonequilibrium met…

Periodically forced pinned anharmonic atom chains
Shiva Darshan, Alessandra Iacobucci, Stefano Olla +1
Recent works proved a hydrodynamic limit for periodically forced atom chains with harmonic interaction and pinning, together with momentum flip. When energy is the only conserved q…

Sticky coupling as a control variate for sensitivity analysis
Shiva Darshan, Andreas Eberle, Gabriel Stoltz
We present and analyze a control variate strategy based on couplings to reduce the variance of finite difference estimators of sensitivity coefficients, called transport coefficien…
