Thermally Increasing Correlation/Modulation Lengths and Other Selection Rules in Systems with Long Range Interactions
Zohar Nussinov
In this article, addressing large systems, we report that in numerous systems hosting long and short range interactions, multiple correlation lengths may appear. The largest co…
Exact ground states of extended t-J_{z} models on a square lattice
Zohar Nussinov, Anders Rosengren
We examine special extended spin S=1/2 fermionic and hard core bosonic t-J_{z} models and find exact ground states. Some of these models display an exponentially large degeneracy w…
The BCS - BEC Crossover In Arbitrary Dimensions
Zohar Nussinov, Shmuel Nussinov
Cold atom traps and certain neutron star layers may contain fermions with separation much larger than the range of pair-wise potentials yet much shorter than the scattering length.…
Non-Relativistic Bose-Einstein Condensates, Kaon droplets, and Q- Balls
Zohar Nussinov, Shmuel Nussinov
We note the similarity between BEC (Bose-Einstein Condensates) formed of atoms between which we have long-range attraction (and shorter-range repulsions) and the field theoretic "Q…
Spin and Current Variations in Josephson Junctions
A. Shnirman, Z. Nussinov, Jian-Xin Zhu +2
We study the dynamics of a single spin embedded in the tunneling barrier between two superconductors. As a consequence of pair correlations in the superconducting state, the spin d…
Orbital ordering in transition-metal compounds: I. The 120-degree model
Marek Biskup, Lincoln Chayes, Zohar Nussinov
We study the classical version of the 120-degree model. This is an attractive nearest-neighbor system in three dimensions with XY (rotor) spins and interaction such that only a par…
