4D ensembles of percolating center vortices and monopole defects: The emergence of flux tubes with -ality and gluon confinement

LE Oxman - Physical Review D, 2018 - APS
Ensembles of magnetic defects represent quantum variables that have been detected and
extensively explored in lattice SU (N) pure Yang-Mills theory. They successfully explain …

Confinement, brane symmetry and the Julia-Toulouse approach for condensation of defects

LS Grigorio, MS Guimaraes, R Rougemont… - Journal of High Energy …, 2011 - Springer
In this work the phenomenon of charge confinement is approached in various contexts. An
universal criterion for the identification of this phenomenon in Abelian gauge theories is …

[HTML][HTML] Massive photons and Dirac monopoles: electric condensate and magnetic confinement

MS Guimaraes, R Rougemont, C Wotzasek, CAD Zarro - Physics Letters B, 2013 - Elsevier
We use the generalized Julia–Toulouse approach (GJTA) for condensation of topological
currents (charges or defects) to argue that massive photons can coexist consistently with …

Effective field theories for superconducting systems with multiple Fermi surfaces

PR Braga, DR Granado, MS Guimaraes, C Wotzasek - Annals of Physics, 2016 - Elsevier
In this work we investigate the description of superconducting systems with multiple Fermi
surfaces. For the case of one Fermi surface we re-obtain the result that the superconductor is …

BF theory as an electric Julia-Toulouse condensate

LS Grigorio, MS Guimaraes, R Rougemont… - Physical Review D …, 2012 - APS
The Julia-Toulouse mechanism is used to show that the topological Abelian BF term may be
induced by the condensation of electric charges. As an application, we discuss the subtle …

[HTML][HTML] U (1) effective confinement theory from SU (2) restricted gauge theory via the Julia–Toulouse approach

LS Grigorio, MS Guimaraes, W Oliveira, R Rougemont… - Physics Letters B, 2011 - Elsevier
We derive a U (1) effective theory of color confinement by applying the so-called Julia–
Toulouse approach for defects condensation to the SU (2) restricted gauge theory defined …

MS Guimaraes, R Rougemont, C Wotzasek… - Physical Review D …, 2012 - APS
The Julia-Toulouse approach for condensation of charges and defects is used to show that
the bosonized Schwinger model can be obtained through a condensation of electric charges …

Chern-Simons term in a dual Josephson junction

LS Grigorio, MS Guimaraes, R Rougemont… - Physical Review D …, 2013 - APS
A dual Josephson junction corresponding to a (2+ 1)-dimensional nonsuperconducting
layer<? format?> sandwiched between two (3+ 1)-dimensional dual superconducting …

Multivalued fields and monopole operators in topological superconductors

PR Braga, MS Guimaraes, MMA Paganelly - Annals of Physics, 2020 - Elsevier
In this work, we investigate the role of multivalued fields in the formulation of monopole
operators and their connection with topological states of matter. In quantum field theory it is …
