Holographic supersolids

Mathematical Issues in the Modeling of Supersolids

Supersolids are quantum crystals having superfluid properties. This state of matter, predicted by Leggett, was achieved experimentally only recently in solid He. In the present paper, we study a model of supersolids introduced in [14, 15]. This model is based on a Gross-Pitaevskii energy with a nonlocal interaction term. We give a description of the ground state in the limit of strong interacti...

Competing supersolids of Bose-Bose mixtures in a triangular lattice

Wess-Zumino terms for relativistic fluids, superfluids, solids, and supersolids.

We use the coset construction of low-energy effective actions to systematically derive Wess-Zumino (WZ) terms for fluid and isotropic solid systems in two, three, and four spacetime dimensions. We recover the known WZ term for fluids in two dimensions as well as the very recently found WZ term for fluids in three dimensions. We find two new WZ terms for supersolids that have not previously appe...

Quantum phase transitions in cuprates: stripes and antiferromagnetic supersolids

It is believed that the magnetic fluctuations in cuprate superconductors reflect the proximity to a quantum phase transition. It will be argued that this notion acquires further credibility if combined with the idea that the superconducting state is in a tight competition with the stripe phase over a large range of hole concentrations. On basis of existing data and some simple considerations, a...

Holographic Optical Elements for Holographic Stereogram Printers

A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...
