Zero-point energy of ultracold atoms

Antiferromagnetism with Ultracold Atoms

We use ultracold spin–1/2 atomic fermions (Li) to realize the Hubbard model on a three-dimensional (3D) optical lattice. At relatively high temperatures and at densities near half-filling, we show that the gas forms a Mott insulator with unordered spins. To observe antiferromagnetic order that is predicted to occur at lower temperatures, we developed the compensated optical lattice method to ev...

Reviewing the Zero Point Energy

A review of recent developments in the study of the Zero Point Energy (ZPE) is made. The origin and behavior of the electromagnetic fields making up the vacuum ZPE is elucidated. From this it is deduced that the ZPE should increase with time even in a static universe such as Narliker and Arp propose. The small oscillations that a static cosmos undergoes will add a variable component to the over...

Quantum Manipulation of Ultracold Atoms

The generation of photon pairs is useful for a broad range of applications, from the fundamental (exclusion of hidden-variable formulations of quantum mechanics) to the more practical (quantum cryptography and quantum computation). A key parameter determining the usefulness of a particular source is its brightness, i.e., how many photon pairs per second are generated into a particular electroma...

Zero-point oscillations in the vicinity of atoms

Nanoplasmonic lattices for ultracold atoms.

We propose to use subwavelength confinement of light associated with the near field of plasmonic systems to create nanoscale optical lattices for ultracold atoms. Our approach combines the unique coherence properties of isolated atoms with the subwavelength manipulation and strong light-matter interaction associated with nanoplasmonic systems. It allows one to considerably increase the energy s...
