Quantum Energy Expectation in Periodic Time-Dependent hamiltonians via Green Functions
Cesar R. de Oliveira, Mariza S. Simsen
Let be the Floquet operator of a time periodic hamiltonian . For each positive and discrete observable (which we call a {\em probe energy}), we derive a formula for…
Plane and parabolic solar panels
J. H. O. Sales, A. T. Suzuki
We present a plane and parabolic collector that absorbs radiant energy and transforms it in heat. Therefore we have a panel to heat water. We study how to increment this capture of…
Closed injective systems and its fundamental limit spaces
Marcio Colombo Fenille
In this article we introduce the concept of limit space and fundamental limit space for the so-called closed injected systems of topological spaces. We present the main results on…
Renormalized coordinate approach to the thermalization process
G. Flores-Hidalgo, A. P. C. Malbouisson, J. M. C. Malbouisson +2
We consider a particle in the harmonic approximation coupled linearly to an environment. modeled by an infinite set of harmonic oscillators. The system (particle--environment) is c…
