Regulating atomic imbalance in double-well lattices
نویسنده
چکیده
An insulating optical lattice with double-well sites is considered. In the case of the unity filling factor, an effective Hamiltonian in the pseudospin representation is derived. A method is suggested for manipulating the properties of the system by varying the shape of the double-well potential. In particular, it is shown that the atomic imbalance can be varied at will and a kind of the Morse-alphabet sequences can be created. PACS: 03.75.Lm; 03.67.Hk; 03.67.Lx

Double-Well Optical Lattices with Atomic Vibrations and Mesoscopic Disorder
Double-well optical lattice in an insulating state is considered. The influence of atomic vibrations and mesoscopic disorder on the properties of the lattice are studied. Vibrations lead to the renormalization of atomic interactions. The occurrence of mesoscopic disorder results in the appearance of first-order phase transitions between the states with different levels of atomic imbalance. The ...
متن کاملGeneration of multiple power-balanced laser beams for quantum-state manipulation experiments with phase-stable double optical lattices
We present a method to obtain power-balanced laser beams for doing quantum-state manipulation experiments with phase-stable double optical lattices. Double optical lattices are constructed using four pairs of overlapped laser beams with different frequencies. Our optical scheme provides a phase stability between the optical lattices of 5 mrad/s, and laser beams with a very clean polarisation st...
متن کاملQuantum-state control in optical lattices
We study the means of preparing and coherently manipulating atomic wave packets in optical lattices, with particular emphasis on alkali-metal atoms in the far-detuned limit. We derive a general, basis-independent expression for the lattice potential operator, and show that its off-diagonal elements can be tailored to couple the vibrational manifolds of separate magnetic sublevels. Using these c...
متن کاملQuantum control and information processing in optical lattices
Neutral atoms offer a promising platform for singleand many-body quantum control, as required for quantum information processing. This includes excellent isolation from the decohering influence of the environment, and the existence of well developed techniques for atom trapping and coherent manipulation. We present a review of our work to implement quantum control and measurement for ultra-cold...
متن کاملMesoscopic disorder in double-well optical lattices
Double-well optical lattices are considered, each cite of which is formed by a doublewell potential. The lattice is assumed to be in an insulating state and order and disorder are defined with respect to the displacement of atoms inside the double-well potential. It is shown that in such lattices, in addition to purely ordered and disordered states, there can exist an intermediate mixed state, ...
