Dissipation-induced geometric phase for an atom in cavity QED
Shi-Biao Zheng
We present a feasible scheme to investigate the geometric phase for an atom trapped in an optical cavity induced by the effective decay process due to cavity photon loss. The cavit…
Jaynes-Cummings model with a collective atomic mode
Shi-Biao Zheng
We study the dynamics of a single control atom and an atomic sample interacting with a nonresonant cavity mode. The control atom is driven by an auxiliary classical field. Under ce…
Arbitrary control of multiple-qubit systems in the symmetric Dicke subspace
Shi-Biao Zheng
We discuss a general physical mechanism for arbitrary control of the quantum states of multiple qubits in the symmetric Dicke subspace. The qubit-qubit coupling leads to unequal en…
Macroscopic superposition and entanglement for displaced thermal fields induced by a single atom
Shi-Biao Zheng
We show that a cavity field can evolve from an initial displaced mixed thermal state to a macroscopic superpositions of displaced thermal states via resonant interaction with a two…
Manifestation of a nonclassical Berry phase of an electromagnetic field in atomic Ramsey interference
Shi-Biao Zheng
The Berry phase acquired by an electromagnetic field undergoing an adiabatic and cyclic evolution in phase space is a purely quantum-mechanical effect of the field. However, this p…
Dicke-like quantum phase transition and vacuum entanglement with two coupled atomic ensembles
Shi-Biao Zheng
We study the coherent cooperative phenomena of the system composed of two interacting atomic ensembles in the thermodynamic limit. Remarkably, the system exhibits the Dicke-like qu…
