Spin and Spin-Wave Dynamics in Josephson Junctions
Zohar Nussinov, Alexander Shnirman, Daniel P. Arovas +2
We extend the Keldysh formulation to quantum spin systems and derive exact equations of motion. This allows us to explore the dynamics of single spins and of ferromagnets when thes…
A Derivation of the Fradkin-Shenker Result From Duality: Links to Spin Systems in External Magnetic Fields and Percolation Crossovers
Zohar Nussinov
In this article, we illustrate how the qualitative phase diagram of a gauge theory coupled to matter can be directly proved and how rigorous numerical bounds may be established. Ou…
Discrete Sliding Symmetries, Dualities, and Self-dualities of Quantum Orbital Compass Models and (p+ip) Superconducting Arrays
Zohar Nussinov, Eduardo Fradkin
We study the spin- 1/2 two and three dimensional Orbital Compass Models relevant to the problem of orbital ordering in transition metal oxides. We show that these systems display s…
Generalized Elitzur's Theorem and Dimensional Reduction
Cristian D. Batista, Zohar Nussinov
We extend Elitzur's theorem to systems with symmetries intermediate between global and local. In general, our theorem formalizes the idea of {\it dimensional reduction}. We apply t…
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-uniform glassy electronic phases from competing local orders
Zohar Nussinov, Ilya Vekhter, Alexander V. Balatsky
We study non-uniform states and possible glassiness triggered by a competition between distinct local orders in disorder free systems. Both in Ginzburg-Landau theories and in simpl…
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…
A Novel Dielectric Anomaly in Cuprates and Nickelates: Signature of an Electronic Glassy State
Tuson Park, Z. Nussinov, K. R. A. Hazzard +8
The low-frequency dielectric response of hole-doped insulators La_{2}Cu_{1-x}Li_{x}O_{4} and La_{2-x}Sr_{x}NiO_{4} shows a large dielectric constant ε^{'} at high temperature and a…
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…
