Heat rectification, heat fluxes, and spectral matching
Javier Navarro, Juan Gonzalo Muga, Marisa Pons
Heat rectifiers would facilitate energy management operations such as cooling, or energy harvesting, but devices of practical interest are still missing. Understanding heat rectifi…
Speed-up and slow-down of a quantum particle
X. Gutiérrez de la Cal, M. Pons, D. Sokolovski
We study non-relativistic propagation of Gaussian wave packets in one-dimensional Eckart potential, a barrier, or a well. In the picture used, the transmitted wave packet results f…
Klein paradox for bosons, wave packets and negative tunnelling times
X. Gutiérrez de la Cal, M. Alkhateeb, M. Pons +2
We analyse a little known aspect of the Klein paradox. A Klein-Gordon boson appears to be able to cross a supercritical rectangular barrier without being reflected, while spending…
Relativistic time-dependent quantum dynamics across supercritical barriers for Klein-Gordon and Dirac particles
M. Alkhateeb, X. Gutierrez de la Cal, M. Pons +2
We investigate wavepacket dynamics across supercritical barriers for the Klein-Gordon and Dirac equations. Our treatment is based on a multiple scattering expansion (MSE). For spin…
Heat rectification with a minimal model of two harmonic oscillators
M. A. Simón, A. Alaña, M. Pons +2
We study heat rectification in a minimalistic model composed of two masses subjected to on-site and coupling linear forces in contact with effective Langevin baths induced by laser…
Time-dependent harmonic potentials for momentum or position scaling
J. G. Muga, S. Martínez-Garaot, M. Pons +2
Cooling methods and particle slowers as well as accelerators are basic tools for fundamental research and applications in different fields and systems. We put forward a generic mec…
