... greater densities than liquids and liquids usually have greater densities than gases. Why? Because solids have particles that are more tightly packed together than liquids and liquids are more tightly packed than gases. Exception to the rule: mercury is a metal that is liquid at room temperature ...

... The ergodic problem in classical mechanics consists in the following: What can be learned about the (statistical) behavior of an ensemble of mechanical (deterministic) systems from the long time behavior of an individual system? Integrable systems do not exhibit any stochastic behavior as the motion ...

On the Control of Open Quantum Systems in the Weak Coupling Limit
... We go back now to the generalized master equation (21) and the kernel operator L = L(ε,t, x) in (19). When developed using the definition of Φε1 and Φε2 and neglecting terms in ε of order 3 or higher, this expression contains functions which measure the correlation of observables on the bath at two ...
