We study the critical exponents of the superconducting phase transition in the context of renormalization group theory starting from a dual formulation of the Ginzburg-Landau theory. The dual formulation describes a loop gas of Abrikosov flux tubes which proliferate when the critical temperature is approached from below. In contrast to the Ginzburg-Landau theory, it has a spontaneously broken global symmetry and possesses an infrared stable fixed point. The exponents coincide with those of a… 
Dual Description of the Superconducting Phase Transition
The dual approach to the Ginzburg-Landau theory of a Bardeen-Cooper-Schrieffer superconductor is reviewed. The dual theory describes a grand canonical ensemble of fluctuating closed magnetic
Critical fluctuations in normal to superconducting transition
Recent advances in our understanding of critical phenomena due to the application1 of the renormalization group (RG) approach2 are now well known (see, e.g., the textbooks3-5). The scale invariance
On the critical fluctuations in superconductors
The field-theoretical gauge model for a superconductor, generalized to an n/2-component complex order parameter is considered. The question of the order of the phase transition occurring in this
Reply to comment on "Continuum dual theory of the transition in 3D lattice superconductor"
It is argued that the penetration depth and the correlation length at the critical point of the 3D superconductor diverge with the same critical exponents, as follows from the general scaling
Critical dynamics, duality, and the exact dynamic exponent in extreme type-II superconductors
The critical dynamics of superconductors is studied using renormalization group and duality arguments. We show that in extreme type-II superconductors the dynamic critical exponent is given exactly
Time-Dependent Ginzburg-Landau Theory and Duality
In the first part of this review paper, the time-dependent Ginzburg-Landau theory is derived starting from the microscopic BCS model with the help of a derivative expansion. Special attention is paid
