Bounding the rotating wave approximation for coupled harmonic oscillators
Tim Heib, Paul Lageyre, Alessandro Ferreri +5
In this work we study the validity of the rotating wave approximation of an ideal system composed of two harmonic oscillators evolving with a quadratic Hamiltonian and arbitrarily…
Spacetime effects on wavepackets of coherent light
David Edward Bruschi, Symeon Chatzinotas, Frank K. Wilhelm +1
We investigate the interplay between gravity and the quantum coherence present in the state of a pulse of light propagating in curved spacetime. We first introduce an operational w…
Matrix Moments in a Real, Doubly Correlated Algebraic Generalization of the Wishart Model
Thomas Guhr, Andreas Schell
The Wishart model of random covariance or correlation matrices continues to find ever more applications as the wealth of data on complex systems of all types grows. The heavy tails…
Exact Multivariate Amplitude Distributions for Non-Stationary Gaussian or Algebraic Fluctuations of Covariances or Correlations
Thomas Guhr, Andreas Schell
Complex systems are often non-stationary, typical indicators are continuously changing statistical properties of time series. In particular, the correlations between different time…
