Superior atomic coherence time controlled by crystal phase transition and optical dressing.
Optics Letters, 2022We compare the atomic coherence time of doped ion crystals, i.e., BiPO4: Eu3+, YPO4: Eu3+, YPO4: Pr3+, and Y2SiO5: Pr3 + crystals. Such atomic coherence time is controlled by crystal field splitting (CF-splitting) and optical (photon and phonon) dressing.

Dual Atomic Coherence in the Self-Assembly of Patchy Heterostructural Nanocrystals.
ACS Nano, 2022Advances in the synthesis and self-assembly of nanocrystals have enabled researchers to create a plethora of different nanoparticle superlattices. But while many superlattices with complex types of translational order have been realized, rotational order

Atomic-scale quantum sensing based on the ultrafast coherence of an H2 molecule in an STM cavity
Science, 2022A scanning tunneling microscope (STM) combined with a pump-probe femtosecond terahertz (THz) laser can enable coherence measurements of single molecules.

Atom Interferometers and Atomic Coherence
Fortschritte der Physik, 1998Atom interferometers are powerful tools for the study of fundamental issues in quantum mechanics. This paper describes the use of our atom interferometer [1] for an experimental realization of Feynman's gedanken experiment in which the observation of photons scattered off of particles emerging from a double slit is used to obtain which path information.

SPIE Proceedings, 2003
The experimental realization of Bose-Einstein condensates in dilute alkali gases has opened up the possibility to perform time and space domain interferometry with coherent matter waves. We have exploited different configurations realizing coherent matter wave interferometers: in a first set of exeperiments we create a twofold condensate sample ...

Atom-laser coherence length and atomic standing waves
Physical Review A, 2000We consider the dynamical Bragg reflection of an atomic matter wave from a finite optical lattice; the resulting energy dependence of the transmittivity allows us to filter out the velocities of the incident atoms. In particular, we show how the coherence length of the incident beam can be inferred from the sharpness of the transmittivity as a function

We explore the limits of atomic coherence and measurement precision in a ^{87}Sr optical lattice clock. We perform a detailed characterization of key effects, including lattice Raman scattering and atomic collisions in a shallow lattice configuration ...

Science, 2002
The past decade has seen dramatic progress in our ability to manipulate and coherently control the motion of atoms. This progress has both fundamental and applied importance. On the one hand, recent experiments are providing new perspectives for the study of quantum phase transitions and highly entangled quantum states.

Excited atomic coherent states
Journal of Modern Optics, 2003Abstract The excited atomic coherent (EAC) states are introduced and some of their statistical properties are discussed. When the Holstein-Primakoff transformations are used then these states become intermediate states interpolating between Fock and displaced Fock states. A generation scheme is discussed.
