Quantum Vacuum Structure and Cosmology (2009)
Rafelski, Johann, Labun, Lance, Hadad, Yaron, Chen, Pisin
Short review of riddles that lie at the intersection of quantum theory, particle physics and cosmology; dark energy as false vacuum; discussion of a possible detection experiment.
Trace Anomaly of Nonlinear Electrodynamics and its (Anti)Gravitational Effect (2008)
Labun, Lance, Rafelski, Johann
Nonlinear electromagnetism, stated as an effective theory, generates energy-momentum tensor trace anomaly density \Tmm in the presence of an electromagnetic field. We evaluate \Tmm explicitly for...
QED Conformal Anomaly in External Fields (2008)
Labun, Lance, Rafelski, Johann
We study the properties of the trace anomaly of the QED energy-momentum tensor in presence of quasi-constant external electromagnetic fields. These vacuum fluctuations act like the dark energy.
Vacuum Decay Time in Strong External Fields (2008)
Labun, Lance, Rafelski, Johann
We consider dynamics of vacuum decay and particle production in the context of short pulse laser experiments. We identify and evaluate the invariant "materialization time," $\tau$, the timescale for...
Running-mode resonance in A.C.-biased periodic potential (2008)
Labun, Lance, Gleiser, Marcelo
We investigate the stochastic dynamics of a particle in the presence of a modulated sinusoidal potential. Using the time derivative of the winding number, we quantify the particle's motion according...
