General relativity, differential geometry, and unitary theories in the work of Mira Fernandes
General relativity differential geometry unitary theories
2010/12/27
An analysis of the work of Mira Fernandes on unitary theories is presented.
A spectral action associated with an Einstein-Cartan formulation of supergravity is proposed. To construct this action we make use of the Seeley-DeWitt coefficients in a Riemann-Cartan space. For con...
Compact formulas for guiding-center orbits in axisymmetric tokamak geometry
Compact formulas guiding-center orbits axisymmetric tokamak geometry
2010/11/16
Compact formulas for trapped-particle and passing-particle guiding-center orbits in axisymmetric tokamak geometry are given in terms of the Jacobi elliptic functions and complete elliptic integrals. ...
Cold atom scattering by cavity fields in a two-dimensional geometry
Cold atom scattering cavity fields two-dimensional geometry
2010/3/10
The quantum theory of the cold atom scattering by cavity fields in a two-dimensional geometry is presented. A distinct regime from the usual Raman-Nath, Bragg and Stern-Gerlach regimes is investigated...
Acoustic excitation of superharmonic capillary waves on a meniscus in a planar micro-geometry
Acoustic excitation superharmonic capillary waves micro-geometry
2010/4/6
The effects of ultrasound on the dynamics of an air-water meniscus in a planar micro-geometry are investigated experimentally. The sonicated meniscus exhibits harmonic traveling waves or standing wave...
