Towards absolute calibration of optical tweezers
N. B. Viana, M. S. Rocha, O. N. Mesquita +3
Aiming at absolute force calibration of optical tweezers, following a critical review of proposed theoretical models, we present and test the results of MDSA (Mie-Debye-Spherical A…
Magnetospheric accretion-ejection processes in the classical T Tauri star AA
J. Bouvier, S. H. P. Alencar, T. Boutelier +8
From a long time series of high resolution (R=115,000) HARPS spectra and simultaneous broad-band photometry, we report new evidence for magnetospheric accretion as well as ejection…
Free energy variational approach for the classical anisotropic XY model in a crystal field
L. M. Castro, A. S. T. Pires, J. A. Plascak
A variational approach for the free energy is used to study the three-dimensional anisotropic XY model in the presence of a crystal field. The magnetization and the phase diagrams…
Atomic detection in microwave cavity experiments: a dynamical model
R. Rossi, M. C. Nemes, J. G. Peixoto de Faria
We construct a model for the detection of one atom maser in the context of cavity Quantum Electrodynamics (QED) used to study coherence properties of superpositions of electromagne…
Pitfalls on the determination of the universality class of radial clusters
S. C. Ferreira, S. G. Alves
The self-affinity of growing systems with radial symmetry, from tumors to grain-grain displacement, has devoted increasing interest in the last decade. In this work, we analyzed fe…
The Casimir Effect for Parallel Plates Revisited
N. A. Kawakami, M. C. Nemes, W. F. Wreszinski
The Casimir effect for a massless scalar field with Dirichlet and periodic boundary conditions (b.c.) on infinite parallel plates is revisited in the local quantum field theory (lq…
