  journal={arXiv: Mathematical Physics},
We establish the consistency conditions for two-particle non relativistic bound states for any three space-time dimensional quantum electrodynamics model (QED$_3$) exhibiting an attractive scattering potential of $K_{_0}$-type, the Bessel-Macdonald function. Initially, we study the self-adjointness of the hamiltonian operator, then by using {\em Seto-type estimates}, an estimate number of two-quantum bound states is derived for any value of the angular momentum. In fact, this result in…

Bound states in one and two spatial dimensions

In this article we study the number of bound states for potentials in one and two spatial dimensions. We first show that in addition to the well-known fact that an arbitrarily weak attractive

Electron?electron bound states in parity-preserving QED3

By considering the Higgs mechanism in the framework of a parity-preserving planar quantum electrodynamics, one shows that an attractive electron–electron interaction may come out. The e− − e−

Electronic bound states in parity-preserving QED3 applied to high-Tc cuprate superconductors

We consider a parity-preserving QED3 model with spontaneous breaking of the gauge symmetry as a framework for the evaluation of the electron–electron interaction potential underlying high-Tc

Bargmann's Inequalities In Spaces of Arbitrary Dimension

An inequality is derived which gives an upper bound of the number of bound states in the Z-th partial wave (Z=0, !,-••) of the two-body Schrodinger equation with a spherically symmetric potential

Two-dimensional gas of massless Dirac fermions in graphene

This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.

QED 3 theory of pairing pseudogap in cuprates: From d-wave superconductor to antiferromagnet via an algebraic Fermi liquid

High-${T}_{c}$ cuprates differ from conventional superconductors in three crucial aspects: the superconducting state descends from a strongly correlated Mott-Hubbard insulator (as opposed to a Fermi

A mass term for three-dimensional gauge fields

Topologically Massive Gauge Theories

Gauge vector and gravity models are studied in three-dimensional space-time, where novel, gauge invariant, P and T odd terms of topological origin give rise to masses for the gauge fields. In the

Introduction to topological superconductivity and Majorana fermions

This short review paper provides a pedagogical introduction to the rapidly growing research field of Majorana fermions in topological superconductors. We first discuss in some detail the simplest
