NSF wants engineering researchers to bend rules (of classical physics)
NSF engineering researchers bend rules classical physics
2016/8/23
The National Science Foundation (NSF) has awarded $18 million to nine teams of engineering-led, interdisciplinary researchers to break the conventional ways in which light and acoustic waves propagate...
A classical particle that is initially in a classically allowed region of a potential is not confined to this region for all time if its energy is complex. Rather, the particle may travel through com...
Time-delay of classical and quantum scattering processes: a conceptual overview and a general definition
Time-delay classical quantum scattering processes conceptual overview general definition
2010/11/8
We present a step by step introduction to the notion of time-delay in classical and quantum mechanics, with the aim of clarifying its foundation at a conceptual level. In doing so, we motivate the in...
In this paper we analyze perturbatively a g phi^4 classical field theory with and without temperature. In order to do that, we make use of a path-integral approach developed some time ago for classic...
One-dimensional universe of free particles: classical and quantum correspondence
Classical-quantum correspondence Wave packets Free particles
2010/3/10
We obtain multi-free particle parametric systems with complete classical-quantum correspondence. First, we quantize the classical parametric model which results in a hyperbolic partial differential eq...
Onset of Classical Behaviour After a Phase Transition
Classical Behaviour a Phase Transition
2010/10/13
We analyze the onset of classical behaviour in a scalar field after a continuous phase transition, in which the system-field, the long wavelength order parameter of the model, interacts with an enviro...
