Alternative energy estimation from the shower lateral distribution function
Vitor de Souza, Carlos O. Escobar, Joel Brito +2
The surface detector technique has been successfully used to detect cosmic ray showers for several decades. Scintillators or Cerenkov water tanks can be used to measure the number…
Extracellular polymeric bacterial coverages as minimal area surfaces
Alberto Saa, Omar Teschke
Surfaces formed by extracellular polymeric substances enclosing individual and some small communities of {\it Acidithiobacillus ferrooxidans} on plates of hydrophobic silicon and h…
The radiation of a uniformly accelerated charge is beyond the horizon: a simple derivation
Camila de Almeida, Alberto Saa
We show, by exploring some elementary consequences of the covariance of Maxwell's equations under general coordinate transformations, that, despite inertial observers can indeed de…
Volume elements and torsion
Ricardo A. Mosna, Alberto Saa
We reexamine here the issue of consistency of minimal action formulation with the minimal coupling procedure (MCP) in spaces with torsion. In Riemann-Cartan spaces, it is known tha…
Quantum-classical correspondence via a deformed kinetic operator
Ricardo A. Mosna, Ian P. Hamilton, Luigi Delle Site
We propose an approach to the quantum-classical correspondence based on a deformation of the momentum and kinetic operators of quantum mechanics. Making use of the factorization me…
Quaternionic bound states
Stefano De Leo, Gisele Ducati
We study the bound-state solutions of vanishing angular momentum in a quaternionic spherical square-well potential of finite depth. As in the standard quantum mechanics, such solut…
