We present an analytic study of a periodic Josephson array with long-range interactions in a transverse magnetic field. We find that this system exhibits a first-order transition into a phase characterized by an extensive number of states separated by barriers that scale with the system size; the associated discontinuity is small in the limit of weak applied field, thus permitting an explicit analysis in this regime.

Quantum glass transition in a periodic long-range Josephson array
AbstractWe show that the ground state of a periodic long-range Josephson array frustrated by a magnetic field is a glass for sufficiently large Josephson energies despite the absence of quenched
An experimentally realizable weiss model for disorder-free glassiness
We summarize recent work on a frustrated periodic long-range Josephson array in a parameter regime where its dynamical behavior is identical to that of the p=4 disordered spherical model. We also
Ground-state and thermal properties of a long-range Josephson array
The ground-state and thermal properties of a two-dimensional array of Josephson coupled superconducting wires is studied. For rational values of the magnetic flux per plaquette, mean-field theory
LETTER TO THE EDITOR: A simple model of a glass with finite-range periodic interactions
In this Letter we introduce a chopped Josephson junction array as a tractable short-ranged frustrated model of a glass without quenched disorder. We study its configurational entropy and conclude
Nonuniform glassy electronic phases from competing local orders
We study nonuniform states and possible glassiness triggered by a competition between distinct local orders in disorder-free systems. Both in Ginzburg-Landau theories and in simple field theories,
Classical and quantum behavior in mean-field glassy systems
In this talk I review some recent developments which shed light on the main connections between structural glasses and mean-field spin glass models with a discontinuous transition. I also discuss the
Structural glass on a lattice in the limit of infinite dimensions
We construct a mean-field theory for the lattice model of a structural glass and solve it using the replica method and one-step replica symmetry breaking ansatz; this theory becomes exact in the
Systematic measurements of electrical magnetoconductivity near the coherence transition of granular DyBa2Cu3O7-δ ultra-thin films are reported. Two type of experiments were performed: diverse current
LETTER TO THE EDITOR: Replica-symmetry breaking in long-range glass models without quenched disorder
We discuss mean-field theory of glasses without quenched disorder focusing on the justification of the replica approach to thermodynamics. We emphasize the assumptions implicit in this method and
Jamming percolation and glass transitions in lattice models.
A new class of lattice gas models with trivial interactions but constrained dynamics is introduced. These models are proven to exhibit a dynamical glass transition: above a critical density rhoc
