Replica-exchange molecular dynamics
Replica-exchange molecular dynamics (REMD) [1] is a tempering method. In this method several replicas of the system are simulated at different temperatures. Every once in a while copies of the system are exchanged.
Thermostats
It has recently been pointed pointed out that one should be very careful which thermostat one employs, the wrong choice leading to non-ergodic behaviour [2]. One should use a canonical ensemble thermostat [3].
