An alternative way to explain how non-commutativity arises in the bosonic string theory
M. A. De Andrade, C. Neves
In this work we will investigate how the non-commutativity arises into the string theory, \textit{i.e.}, how the bosonic string theory attaches to a D3-brane in the presence of mag…
Noncommutative Mapping from the symplectic formalism
M. A. De Andrade, C. Neves
The Bopp's shifts will be generalized through symplectic formalism. A special procedure, like a "diagonalization", which drives the completely deformed symplectic matrix to the sta…
Vortex Solutions and a Novel Role for R-parity in an N=2-Supersymmetric Model for Graphene
Everton M. C. Abreu, Marco A. De Andrade, Leonardo P. G. De Assis +3
In a previous work, we have been able to settle Jackiw's et al. chiral gauge theory for Dirac fermions in graphene in an N=1 supersymmetric framework, using a tau3-QED prescription…
Mass Generation and Related Issues from Exotic Higher Dimensions
M. Rojas, M. A. De Andrade, L. P. Colatto +3
The main purpose of this work is to show that massless Dirac equation formulated for non-interacting Majorana-Weyl spinors in higher dimensions, particularly in D=1+9 and D=5+5, ca…
A supersymmetric model for graphene
Everton M. C. Abreu, Marco A. De Andrade, Leonardo P. G. de Assis +3
In this work, we focus on the fermionic structure of the low-energy excitations of graphene (a monolayer of carbon atoms) to propose a new supersymmetric field-theoretic model for…
Unconstrained Variables of Non-Commutative Open Strings
M. A. De Andrade, M. A. Santos, I. V. Vancea
The boundary conditions of the bosonic string theory in non-zero -field background are equivalent to the second class constraints of a discretized version of the theory. By proj…
The Signature Triality of Majorana-Weyl Spacetimes
M. A. De Andrade, M. Rojas, F. Toppan
Higher dimensional Majorana-Weyl spacetimes present space-time dualities which are induced by the Spin(8) triality automorphisms. Different signature versions of theories such as 1…
Superpropagators for explicitly broken 3D-supersymmetric theories
J. L. Boldo, L. P. Colatto, M. A. De Andrade +2
A systematic algorithm to derive superpropagators in the case of either explicitly or spontaneously broken supersymmetric three-dimensional theories is presented. We discuss how th…
Real Structures in Clifford Algebras and Majorana Conditions in Any Space-time
M. A. De Andrade, F. Toppan
Clifford algebras and Majorana conditions are analyzed in any spacetime. An index labeling inequivalent -structures up to orthogonal conjugations is introduced. Inequivalent cha…
Renormalization of the N=1 Abelian Super-Chern-Simons Theory Coupled to Parity-Preserving Matter
L. P. Colatto, M. A. De Andrade, O. M. Del Cima +3
We analyse the renormalizability of an Abelian N=1 super-Chern-Simons model coupled to parity-preserving matter on the light of the regularization independent algebraic method. The…
Electron-pair condensation in parity-preserving QED3
M. A. De Andrade, O. M. Del Cima, J. A. Helayël-Neto
In this paper, we present a parity-preserving QED3 with spontaneous breaking of a local U(1)-symmetry. The breaking is accomplished by a potential of the \vf^6-type. It is shown th…
Some Properties of Charge-Conjugated Spinors in dimensions
M. A. De Andrade
Spinors for an arbitrary Minkowski space with signature (, ) are reassessed in connection with -dimensional free Dirac action. The possibility of writing down kinetic and…
