... A metastable system trapped in a local minimum of the free energy can decay to lower energy states in two ways. Classically, the system may decay by acquiring thermal energy greater than the depth of the local energy well (the activation energy). However, even in the absence of thermal fluctuations, ...

This classical constraint gives at the quantum level a modification on the electric field observable restricting the expectation value of its parallel component to zero on the surface of the mirror [20]. Consider the case where due to the mirror the radiation ...

Quantum scattering
... In this way, for any finite value of the radius R of the box, we have mapped our scattering system into a bound system with a spectral density d(E; R) over discrete eigenenergies En (R). It is therefore important that our scattering potential was chosen to be short-ranged to start with. (Which expla ...

Let a given density of particles n(x) ≥ 0, can we find a minimizer of the quantum free energy among the density operators % having n(x) as local density, ...
