Ground State Energy of Massive Scalar Field Inside a Spherical Region in the Global Monopole Background

E. R. Bezerra de Mello, V. B. Bezerra, N. R. Khusnutdinov

Using the zeta function regularization method we calculate the ground state energy of scalar massive field inside a spherical region in the space-time of a point-like global monopo…

Landau Levels in the Presence of Topological Defects

G. de A. Marques, Claudio Furtado, V. B. Bezerra +1

We study the Landau levels associated with electrons moving in a magnetic field in the presence of a continuous distribution of disclinations, a magnetic screw dislocation and a di…

Relativistic Quantum Scattering on a Cone

J. Spinelly, E. R. Bezerra de Mello, V. B. Bezerra

We study the relativistic quantum mechanical scattering of a bosonic particle by an infinite straight cosmic string, considering the non-minimal coupling between the bosonic field…

Vaccum Polarization for a Massless Scalar Field in the Global Monopole Spacetime at Finite Temperature

F. C. Carvalho, E. R. Bezerra de Mello

In this paper we calculate the effects produced by temperature in the renormalized vaccum expectation value of the square of the massless scalar field in the pointlike global monop…

Electrostatic in Reissner-Nordstrom space-time with a conical defect

J. Spinelly, V. B. Bezerra

We calculate the electrostatic potential generated by a point charge in the space-time of Reissner-Nordstrom with a conical defect. An expression for the self-energy is also presen…

Radiatively Induced Lorentz and CPT Violation in QED at Finite Temperature

J. R. S. Nascimento, R. F. Ribeiro, N. F. Svaiter

In this paper we evaluate the induced Lorentz and CPT violating Chern-Simons term in the QED action at finite temperature. We do this using the method of derivative expansion of fe…

Precision measurements of the Lambda_c+ and D0 lifetimes

The SELEX collaboration, A. Kushnirenko

We report new precision measurements of the lifetimes of the Lambda_c+ and D0 from SELEX, the charm hadro-production experiment at Fermilab. Based upon 1630 Lambda_c+ and 10210 D0…

Dilaton Gravity with a Non-minmally Coupled Scalar Field

M. Alves, V. B. Bezerra

We discuss the two-dimensional dilaton gravity with a scalar field as the source matter. The coupling between the gravity and the scalar, massless, field is presented in an unusual…

Entrapment of a Network of Domain Walls

D. Bazeia, F. A. Brito

We explore the idea of a network of defects to live inside a domain wall in models of three real scalar fields, engendering the Z_2 x Z_3 symmetry. The field that governs the Z_2 s…

Casimir and van der Waals force between two plates or a sphere (lens) above a plate made of real metals

G. L. Klimchitskaya, U. Mohideen, V. M. Mostepanenko

The Casimir and van der Waals forces acting between two metallic plates or a sphere (lens) above a plate are calculated accounting for the finite conductivity of the metals. The si…

Self-Dual Model Coupled to Bosons

M. A. Anacleto, J. R. S. Nascimento, R. F. Ribeiro

In this paper we investigated the dynamics, at the quantum level, of the self-dual field minimally coupled to bosons. In this investigation we use the Dirac bracket quantization pr…
