چکیده
We plan to answer this question with the Munich micromaser in mind [1]. It consists of a superconducting cavity maintained at T = 0.3K. Hence, the average thermal photons present in the cavity is n̄th = 0.033. The cavity dissipation parameter κ = ν/2Q stands at 3.146 Hz with the cavity Q = 3.4×109 and ν being the masing frequency. A clever velocity selector sends Rb atoms in the upper of its two Rydberg levels into the cavity at such a rate that at most one atom is present there at a time. Also, the velocity selector maintains a constant flight time for each and every atom through the cavity. This is crucial for the Jaynes-Cummings [2] interaction between the single mode of the cavity and the atom present there. The attempt is to generate a Fock state of the cavity radiation field. To start with, the cavity is in thermal equilibrium having the normalized variance

Several pairing schemes currently used to describe superfluid nuclei through Hartree-Fock-Bogolyubov (HFB) calculations are briefly reviewed. We put a particular emphasis on the regularization recipes used in connection with zero-range forces and on the density dependence which usually complement their definition. Regarding the chosen regularization process, the goal is not only to identify the...

We study su(2) and su(1,1) displaced number states. Those states are eigenstates of density-dependent interaction systems of quantized radiation field with classical current. Those states are intermediate states interpolating between number and displaced number states. Their photon number distribution, statistical and squeezing properties are studied in detail. It is show that these states exhi...

We construct the exchange gate with small elementary gates on the space of qudits, which consist of three controlled shift gates and three ”reverse” gates. This is a natural extension of the qubit case. We also consider a similar subject on the Fock space, but in this case we meet with some different situation. However we can construct the exchange gate by making use of generalized coherent ope...

The numerical solution of the recently formulated number-projected Hartree-Fock-Bogoliubov equations is studied in an exactly soluble cranked-deformed shell model Hamiltonian. It is found that the solution of these number-projected equations involve similar numerical effort as that of bare HFB. We consider that this is a significant progress in the mean-field studies of the quantum many-body sy...
