Coordinate representation of particle dynamics in AdS and in generic static spacetimes
particle dynamics AdS generic static spacetimes
2010/12/23
We discuss the quantum dynamics of a particle in static curved spacetimes in a coordinate representation. The scheme is based on the analysis of the squared energy operator E^2, which is quadratic in ...

Universal Markovian reduction of Brownian particle dynamics
Markovian reduction Brownian particle dynamics
2010/11/8
Non-Markovian processes can often be turned Markovian by enlarging the set of variables. Here we show, by an explicit construction, how this can be done for the dynamics of a Brownian particle obeying...
Klein tunneling in carbon nanostructures: a free particle dynamics in disguise
Klein tunneling carbon nanostructures particle dynamics disguise
2010/11/9
The absence of backscattering in metallic nanotubes as well as perfect Klein tunneling in the potential barriers in graphene are explained by showing that both phenomena have a free particle dynamics...
