Vacuum fluctuations and moving atoms/detectors: From Casimir

At some threshold value the barrier height will fall below the classical tunnelling height and no atoms will be reflected. Th ...

Is spacetime a quantum error-correcting code?
... So at least in the one case where we think we understand how quantum gravity works, a black hole seems not to destroy information! Even so, the mechanism by which information can escape from behind a putative event horizon remains murky. Indeed, it is not clear whether or how the boundary theory des ...

CCR 7: Derivation of the Boltzmann Distribution
... Consider an isolated system, whose total energy is therefore constant, consisting of an ensemble of identical particles1 that can exchange energy with one another and thereby achieve thermal equilibrium. In order to simplify the numerical derivation, we will assume that the energy E of any individua ...

We assume either that the particle is spinless, or that the spin degrees of freedom can be ignored. For most of these notes we make ...

The classical and quantum Fourier transform
... For our purposes, the Fourier transform is going to be an N × N unitary matrix, all of whose entries have the same magnitude. For N = 2, it’s just our familiar Hadamard transform: ...
