Renormalization of the scalar theory under Robin boundary conditions and a possible new renormalization ambiguity
Luiz C de Albuquerque
We perform a detailed analysis of renormalization at one-loop order in the theory with Robin boundary condition (characterized by a constant ) on a single plate at .…
Quantum Topology Change and Large N Gauge Theories
Luiz C. de Albuquerque, Paulo Teotonio-Sobrinho, Sachindeo Vaidya
We study a model for dynamical localization of topology using ideas from non-commutative geometry and topology in quantum mechanics. We consider a collection of one-dimensi…
Casimir effect for the scalar field under Robin boundary conditions: A functional integral approach
Luiz C. de Albuquerque, R. M. Cavalcanti
In this work we show how to define the action of a scalar field in a such a way that Robin boundary condition is implemented dynamically, i.e., as a consequence of the stationary a…
Fluctuating Commutative Geometry
Luiz C. de Albuquerque, Jorge L. deLyra, Paulo Teotonio-Sobrinho
We use the framework of noncommutative geometry to define a discrete model for fluctuating geometry. Instead of considering ordinary geometry and its metric fluctuations, we consid…
Uniaxial Lifshitz Point at
Luiz C. de Albuquerque, Marcelo M. Leite
The critical exponents and of a uniaxial Lifshitz point are calculated at two-loop level using renormalization group and -expansion techniques. We…
Renormalization Ambiguities in Casimir Energy
Luiz C. de Albuquerque
Some questions were recently raised about the equivalence of two methods commonly used to compute the Casimir energy: the mode summation approach and the one-loop effective potenti…
