Single ions trapped in a one-dimensional optical lattice.
We report on three-dimensional optical trapping of single ions in a one-dimensional optical lattice formed by two counterpropagating laser beams. We characterize the trapping parameters of the standing-wave using the ion as a sensor stored in a hybrid trap consisting of a radio-frequency (rf), a dc, and the optical potential. When loading ions directly from the rf into the standing-wave trap, w...
متن کاملOne-dimensional phase transitions in a two-dimensional optical lattice
A phase transition for bosonic atoms in a two-dimensional anisotropic optical lattice is considered. If the tunnelling rates in two directions are different, the system can undergo a transition between a two-dimensional superfluid and a one-dimensional Mott insulating array of strongly coupled tubes. The connection to other lattice models is exploited in order to better understand the phase tra...
متن کاملDetecting Single , Trapped Ions
We have designed and constructed an experiment to trap a single ion in a Penning trap and measure its motion with an RF SQUID-based, superconducting detector. Using this apparatus we have detected the axial motion of a single, trapped N ion. We describe the theory of ion motion in an imperfect Penning trap and use this theory to explain our measurements on trapped ions. We describe and demonstr...
متن کاملTopological charge pumping in a one-dimensional optical lattice.
A topological charge pump transfers charge in a quantized fashion. The quantization is stable against the detailed form of the pumping protocols and external noises and shares the same topological origin as the quantum Hall effect. We propose an experimental setup to realize topological charge pumping of cold fermionic atoms in a one-dimensional optical lattice. The quantization of the pumped c...
متن کاملManipulating topological edge spins in a one-dimensional optical lattice.
We propose to observe and manipulate topological edge spins in a one-dimensional optical lattice based on currently available experimental platforms. Coupling the atomic spin states to a laser-induced periodic Zeeman field, the lattice system can be driven into a symmetry protected topological (SPT) phase, which belongs to the chiral unitary (AIII) class protected by particle number conservatio...
