Quantum Field Theory on Curved Backgrounds. II
... the isometry group is generated by one-parameter subgroups which have either selfadjoint or unitary quantizations. We then show that the self-adjoint semigroups thus constructed can be analytically continued to one-parameter unitary groups, and using this analytic continuation we construct a unitary ...

... RT absorption spectrum of a GaAs/ Al0.28Ga0.72As MQW structure containing 77 GaAs quantum wells of width 10 nm. The spectrum of GaAs at the same temperature is shown for comparison. Detailed analysis reveals that the binding energies of the quantum well excitons are about 10 me, higher than the valu ...

Let us now consider a system of electrons (described by an Hamiltonian H0 which is not specified at the moment) that is paramagnetic, namely, there is no net magnetization at equilibrium. In other words, hSi vanishes. However, when one applies a magnetic f ...

... Any object (including atoms) can emit or absorb only certain quantities of energy. Energy is quantized; it occurs in fixed quantities, rather than being continuous. Each fixed quantity of energy is called a quantum. An atom changes its energy state by emitting or absorbing one or more quanta of ener ...
