On the AdS/BCFT Approach to Quantum Hall Systems
Dmitry Melnikov, Emanuele Orazi, Pasquale Sodano
In this paper we study a simple gravity model dual to a (2+1)-dimensional system with a boundary at finite charge density and temperature. In our naive AdS/BCFT extension of a well…
Superconductors with Topological Order and their Realization in Josephson Junction Arrays
M. C. Diamantini, P. Sodano, C. A. Trugenberger
We will describe a new superconductivity mechanism, proposed by the authors in [1], which is based on a topologically ordered ground state rather than on the usual Landau mechanism…
Superconductors with Topological Order
M. C. Diamantini, P. Sodano, C. A. Trugenberger
We propose a mechanism of superconductivity in which the order of the ground state does not arise from the usual Landau mechanism of spontaneous symmetry breaking but is rather of…
An O(N) symmetric extension of the Sine-Gordon Equation
Fred Cooper, Pasquale Sodano, Andrea Trombettoni +1
We discuss an O(N) exension of the Sine-Gordon (S-G)equation which allows us to perform an expansion around the leading order in large-N result using Path-Integral methods. In lead…
Spectrum of the 2-Flavor Schwinger Model from the Heisenberg Spin Chain
F. Berruto, G. Grignani, G. W. Semenoff +1
We study the strong coupling limit of the 2-flavor lattice Schwinger model in the Hamiltonian formalism using staggered fermions. We show that the problem of finding the low-lying…
Loop Correlators and Theta States in 2D Yang-Mills Theory
G. Grignani, L. Paniak, G. W. Semenoff +1
Explicit computations of the partition function and correlation functions of Wilson and Polyakov loop operators in theta-sectors of two dimensional Yang-Mills theory on the line cy…
G/G models as the strong coupling limit of topologically massive gauge theory
G. Grignani, G. Semenoff, P. Sodano +1
We show that the problem of computing the vacuum expectation values of gauge invariant operators in the strong coupling limit of topologically massive gauge theory is equivalent to…
Quantum States of Topologically Massive Electrodynamics and Gravity
G. Grignani, P. Sodano, C. A. Scrucca
The free quantum states of topologically massive electrodynamics and gravity in 2+1 dimensions, are explicitly found. It is shown that in both theories the states are described by…
Charge Screening and Confinement in Hot 3-D QED
G. Grignani, G. Semenoff, P. Sodano +1
We examine the possibility of a confinement-deconfinement phase transition at finite temperature in both parity invariant and topologically massive three-dimensional quantum electr…
Gauge Theories of Josephson Junction Arrays
M. C. Diamantini, P. Sodano, C. A. Trugenberger
We show that the zero-temperature physics of planar Josephson junction arrays in the self-dual approximation is governed by an Abelian gauge theory with periodic mixed Chern-Simons…
Hidden supersymmetry of a invariant fermion system
Mikhail Plyushchay, Pasquale Sodano
We show that a (2+1)-dimensional invariant free fermion system, relevant to conserving models of high- superconductivity, has a U(1,1) dynamical symmetry as well a…
A Pseudoclassical Model for Invariant Planar Fermions
G. Grignani, M. Plyushchay, P. Sodano
A pseudoclassical model is proposed for the description of planar invariant massive fermions. The quantization of the model leads to the (2+1)-dimensional invariant fer…
Confinement-Deconfinement Transition in 3-Dimensional QED
G. Grignani, G. Semenoff, P. Sodano
We argue that, at finite temperature, parity invariant non-compact electrodynamics with massive electrons in 2+1 dimensions can exist in both confined and deconfined phases. We sho…
Polyakov Loops in 2D QCD
G. Grignani, G. Semenoff, P. Sodano
We discuss SU(N) gluo-dynamics at finite temperature and on a spatial circle. We show that the effective action for the Polyakov Loop operator is a one dimensional gauged SU(N) pri…
Self Duality and Oblique Confinement in Planar Gauge Theories
M. C. Diamantini, P. Sodano, C. A. Trugenberger
We investigate the non-perturbative structure of two planar lattice gauge models and discuss their relevance to two-dimensional condensed matter systems and Joseph…
Classical and quantum dissipation in non homogeneous environments
F. Illuminati, M. Patriarca, P. Sodano
We generalize the oscillator model of a particle interacting with a thermal reservoir by introducing arbitrary nonlinear couplings in the particle coordinates.The equilibrium posit…
