Basic Notions of Entropy and Entanglement
... 1. Classical Entropy and Information As with many scientific terms taken over from common language, the scientific meaning of information is related to, but narrower and more precise than, the everyday meaning. We think of information as relieving uncertainty, and this is the aspect emphasized in Sh ...

Rotational Motion
... a)v = ωr and ω=2π rad/4 sec = 1.6 rad/s since r = 1.2 m then v = 1.58 rad/s x 1.2 m = 1.9 m/s b) Since the linear velocity is not changing there is no linear or tangential acceleration, but the child is moving in a circle so there is centripetal or radial acceleration which you will recall fits the ...

Our starting point is the observation made many years ago by Purcell' that the spontaneous emission rate A for a two-state system is increased if the atom is surrounded by a cavity tun ...

“Mind the gap” Solving optimization problems with a
... In satisfiability problems (SAT) we ask whether there is an assignment of N bits which satisfies all of M logical conditions (“clauses”). We assign an energy to each clause such that it is zero if the clause is satisfied and a positive value if not satisfied. i.e. We need to determine if the ground ...

Broken symmetry revisited - Homepages of UvA/FNWI staff
... In addition to the aforementioned characteristics in the spectrum of fundamental excitations, there are in general other fingerprints of a broken symmetry in a physical system. These are usually called topological excitations or just defects and correspond to collective degrees of freedom carrying ‘ ...
