Lattice-Boltzmann as a thermostat: Solvent Coarse-Graining •Long range interactions might play a role •Electrostatics •Hydrodynamic interaction •Usual thermostats are neither momentum-preserving, nor local •Example: Nosè-Hoover thermostat non Galileian-invariant: momentum preserved only when COM is at rest non local: momentum preserved only globally Tuesday, October 8, 2013
Lattice-Boltzmann as a thermostat: Solvent Coarse-Graining •Several options: DPD, SRD, LB •for LB: Ahlrichs-Dünweg coupling •Langevin eq. guarantees proper thermalization •Provides a meaningful coupling to the fluid Tuesday, October 8, 2013
