Bosonic Theory with a Random Defect Line

Marco Moriconi

Published Feb 17, 2005• 1 citation

Abstract

We study a two-dimensional bosonic field theory with a random defect line. The theory has a background field coupled to the field variables at the defect line, which renders the model non-integrable. However, as the background field is random, and the disorder is implemented through the replica trick, the model becomes integrable, allowing us to use the form-factor method to compute the exact correlation functions of the quenched model.

Invalidity of the replica trick for a two-dimensional fermion model

K. Ziegler

Non-interacting fermions in a random potential are considered on a square lattice. Such a model was previously proposed as a description of the quenched thermodynamics of a disordered Ising model. The author compares in a perturbative approach the replica trick and a formal functional integral representation and find that they yield different results.

Random walk with a boundary line as a free massive boson with a defect line

A Valleriani

We show that the problem of a random walk with a boundary attractive potential may be mapped onto the free massive bosonic quantum field theory with a defect line. This mapping allows us to recover the statistical properties of random walks by using boundary S-matrix and form factor techniques.

Superfluids, Fluctuations and Disorder

Alberto Cappellaro, Luca Salasnich

We present a field-theory description of ultracold bosonic atoms in the presence of a disordered external potential. By means of functional integration techniques, we aim to investigate and review the interplay between disordered energy landscapes and fluctuations, both thermal and quantum ones. Within the broken-symmetry phase, up to the Gaussian level of approximation, the disorder contribution crucially modifies both the condensate depletion and the superfluid response. Remarkably, it is found that the ordered (i.e., superfluid) phase can be destroyed also in regimes where the random external potential is suitable for a perturbative analysis. We analyze the simplest case of quenched disorder and then we move to present the implementation of the replica trick for ultracold bosonic systems. In both cases, we discuss strengths and limitations of the reviewed approach, paying specific attention to possible extensions and the most recent experimental outputs.

Fusion of Integrable Defects and the Defect $g$-Function

Yang He, Yunfeng Jiang, Yuxiao Liu

We study exact defect $g$-functions for integrable line defects in two-dimensional integrable quantum field theory and use them to probe defect fusion. We consider three settings: fusion of purely transmitting topological defects, fusion of non-topological defects with reflection and transmission, and fusion of a defect with an integrable boundary. For topological defects, the separated logarithmic $g$-function is additive, and the fusion limit is controlled by the multiplicative composition of transmission factors. For non-topological defects, separation-dependent phases in the Bethe-Yang equations produce oscillatory finite-size effects, while the fused defect is described by effective reflection and transmission amplitudes. In the Ising examples studied here, fusion involving non-topological defects lowers the finite localized contribution to the entropy, whereas topological defect-boundary fusion leaves it unchanged.

On the fermion-boson correspondence for correlation functions of disorder operators

Delfino, G, Grinza, P, Mussardo, G

When a quantum field theory possesses topological excitations in a phase with spontaneously broken symmetry, these are created by operators which are non-local with respect to the order parameter. Due to non-locality, such disorder operators have non-trivial correlation functions even in free massive theories. In two dimensions, these correlators can be expressed exactly in terms of solutions of non-linear differential equations. The correlation functions of the one-parameter family of non-local operators in the free charged bosonic and fermionic models are the inverse of each other. We point out a simple derivation of this correspondence within the form factor approach
