Random Matrix Theory - Are you sure you want to look at this?

... We can test this by trying a different ensemble. For example, let’s try random symmetric matrices filled with +-1. In the past, we’ve created these matrices the hard way. But let’s just take the signs of the matrix elements generated by the GOE ensemble!In the past, we’ve created these matrices the ...

... In order to apply the Born equation (10.2), we need to know the radius of the corresponding ions. These numbers can be obtained from Table 23.3 r(Br-) = 196 pm; r(Cl-) = 181 pm; thus ∆solvGө(Br-, aq) - ∆solvGө (Cl-, aq) = - (1/196 – 1/181)*6.86*104 kJ mol-1 = 29.00 kJ mol-1 (The calculated result is ...

... This is the force exerted by the spring. The external force we exert on the spring is Fext = + k x. The proportionality constant k is known as the spring constant and describes how stiff the spring is. Now we are again ready to ask "How much work is done when we stretch a spring a distance x from it ...

Eigenstate thermalization hypothesis

The Eigenstate Thermalization Hypothesis (or ETH) is a set of ideas which purports to explain when and why an isolated quantum mechanical system can be accurately described using equilibrium statistical mechanics. In particular, it is devoted to understanding how systems which are initially prepared in far-from-equilibrium states can evolve in time to a state which appears to be in thermal equilibrium. The phrase ""eigenstate thermalization"" was first coined by Mark Srednicki in 1994, after similar ideas had been introduced by Josh Deutsch in 1991. The principal philosophy underlying the eigenstate thermalization hypothesis is that instead of explaining the ergodicity of a thermodynamic system through the mechanism of dynamical chaos, as is done in classical mechanics, one should instead examine the properties of matrix elements of observable quantities in individual energy eigenstates of the system.
