Emergent Z_2 gauge symmetry and spin-charge separation in one dimensional physics
H. V. Kruis, Z. Nussinov, J. Zaanen
We demonstrate that in the scaling limit the phenomenon of spin-charge separation as encountered in Luttinger liquids defined on the lattice can be associated with the emergence of…
Topological Charge Order and Binding in a Frustrated XY Model and Related systems
Zohar Nussinov
We prove the existence of a finite temperature Z_{2} phase transition for the topological charge ordering within the Fully Frustrated XY Model. Our method enables a proof of the to…
O(n) Spin Systems- Some General Properties: A Generalized Mermin-Wagner-Coleman Theorem, Ground States, Peierls Bounds, and Dynamics
Z. Nussinov
Here we examine O(n) systems with arbitrary two spin interactions (of unspecified range) within a general framework. We shall focus on translationally invariant interactions. In th…

Commensurate and Incommensurate O(n) Spin Systems: Novel Even-Odd Effects, A Generalized Mermin-Wagner-Coleman Theorem, and Ground States
Zohar Nussinov
We examine n component spin systems with arbitrary two spin interactions (of unspecified range) within a general framework to highlight some new subtleties present in incommensurat…
An Exact Solution to a Three Dimensional Ising Model and Dimensional Reductions
Z. Nussinov
A high temperature expansion is employed to map some complex anisotropic nonhermitian three and four dimensional Ising models with algebraic long range interactions into a solvable…
Singular Fermi Liquids
C. M. Varma, Z. Nussinov, W. van Saarloos
An introductory survey of the theoretical ideas and calculations and the experimental results which depart from Landau Fermi-liquids is presented. Common themes and possible routes…
Exact Solutions to Special High Dimensional O(n) Models, Dimensional Reductions, gauge redundancy, and special Frustrated Spin and Orbital models
Zohar Nussinov
This work addresses models (e.g. potential models of directed orbital systems- the manganates) in which an effective reduction dimensionality occurs as a result of a new symmetry w…
The geometric order of stripes and Luttinger liquids
J. Zaanen, O. Y. Osman, H. V. Kruis +2
It is argued that the electron stripes as found in correlated oxides have to do with an unrecognized form of order. The manifestation of this order is the robust property that the…
