Abstract

We study the two-excitation system comprising two two-level atoms resonantly interacting with two coupled cavities.The evolution of the state vector of the system is given.By means of the numerical calculations,we investigate the evolution of the second-order correlation function of the field and that of Mandel Q function.The influences of coupling constant between cavities and state-selective measurement of the atom on the second-order correlation function and Mandel Q function are discussed.The results obtained show that the second-order correlation function or Mandel Q function has a nonlinear relation with increasing of the cavity-cavity coupling coefficient.On the other hand,the sub-Poissonian distribution of the field can be strengthened through the state-selective measurement on the atom.

The two-excitation system comprising two two-level atoms resonantly interacting with two coupled cavities is analyzed.The evolution of the state vector of the system is given when the total excitation number equals two.By means of the numerical calculations,the temporal evolution in the entanglement is investigated between the atoms,between the cavities,as well as between the atom and the local cavity mode.The influences of coupling constant between cavities on the entanglements are discussed.The results obtained show that atom and atom are separable,and the cavity-cavity entanglement and the atom-cavity entanglement are weakened with increasing of the coupling constant between cavities.

Quantum properties in the system of atom interacting with twomode cavity

We consider the system which is composed of a two-level atom and a two-mode cavity,and two modes are coupled in the cavity.The evolution of the state vector of the system is given.The squeezing,antibunching effect and the photon number statistical distribution of two-mode field are investigated.First,through calculating the fluctuations of two quadrature components of the field,we get that a-mode and b-mode of two-mode field do not both display squeezing.Second,by calculating second-order correlation function of two-mode field,the results show that a-mode and b-mode of two-mode field both display antibunching effects,and there is anti-correlation between the two modes.Third,by means of the numerical calculations,we plot evolution curves of Mandel Q function for different values of the coupling constants between two modes.Through comparing these curves,the influence of coupling constant between two modes on the photon number statistical distribution of the field is discussed.The evolution curves of Mandel Q function show that the two-mode cavity field displays sub-Poisson distribution.Moreover,the sub-Poisson distribution is weakened with increasing of the coupling constant between two modes.

Entanglement dynamics in the system of W-like states atoms interacting with coupled cavities

LU Dao-min

In this paper,we consider the situation that two of three identical two-level atoms are trapped in two coupled cavities separately and another atom is outside the cavity.The evolution of the state vector of the system is given.Three atoms are in like-W state,and optical cavities are all in vacuum state initially.Negativity is adopted to quantify the degree of entanglement.By means of the numerical calculations,we investigate the temporal evolutions of the entanglement between atoms.The influences of coupling constant between cavities and the parameter describing the atomic initial state on the entanglements are discussed.The results show that the disentanglement time zone of atom-atom entanglement is reduced,and the curve peaks of entanglements increase as initial entanglement between atoms increases.This indicates that the entanglement between atoms is strengthened with the increase of initial entanglement between atoms.The atom-atom entanglement is also strengthened with the increase of the coupling constant between cavities.On the other hand,we consider the case which the state of atom outside cavity is measured.When a direct selective measurement is performed or not,the effect of the state-selective measurement on the entanglement is discussed.We find that the entanglement between atoms can be strengthened through the state-selective measurement.

The entanglement properties in the system of two double-level atoms trapped in two coupled cavities

LU Dao-min

We consider a system consisting of two two-level atoms interacting with two coupled cavities via a two-photon hopping.Two atoms are individually trapped in two coupled cavities.The evolution of the state vector of the system is given by solving the Schrodinger equation.Negativity is used to quantify the degree of entanglement.By means of the numerical calculations,we investigate the temporal evolution in the entanglement between atoms and that between atom and cavity.Through comparing the results of different cavity-cavity coupling coefficients,the influence of cavity-cavity coupling coefficient on the entanglement is discussed.The obtained results show that the atom-atom entanglement and atom-cavity entanglement both display the evolution which is from the irregular oscillations to quasi-periodic oscillation with the cavity-cavity coupling coefficient increasing.The average value of atom-atom entanglement and that of atom-cavity entanglement sometimes increase and sometimes decrease.It shows that there is non-linear relationship between atom-atom entanglement and cavity-cavity coupling coefficient,or between atom-cavity entanglement and cavity-cavity coupling coefficient.On the other hand,when the cavity-cavity coupling coefficient is small,the entanglement between atom and cavity exhibits the phenomenon of collapse and recovery.

Two coupled cavities each containing one two-level atom are considered,which interacts with cavity via a two-photon hopping.The evolution of the state vector of the system is given when the total excitation number equals two.The squeezing of field is investigated.By means of the numerical calculations,the influences of cavity-cavity coupling constant and atom-cavity coupling constant on the antibunching effect of field are discussed.The obtained results show that the field does not display squeezing,and the antibunching effect of field has a nonlinear relation with cavity-cavity coupling constant or atom-cavity coupling constant.
