WKB Propagation of Gaussian Wavepackets
Raphael N. P. Maia, Fernando Nicacio, Raul O. Vallejos +1
We analyze the semiclassical evolution of Gaussian wavepackets in chaotic systems. We prove that after some short time a Gaussian wavepacket becomes a primitive WKB state. From the…
Husimi-Wigner representation of chaotic eigenstates
Fabricio Toscano, Anatole Kenfack, Andre R. R. Carvalho +2
Just as a coherent state may be considered as a quantum point, its restriction to a factor space of the full Hilbert space can be interpreted as a quantum plane. The overlap of suc…
Semiclassical spatial correlations in chaotic wave functions
Fabricio Toscano, Caio H. Lewenkopf
We study the spatial autocorrelation of energy eigenfunctions corresponding to classically chaotic systems in the semiclassical regime. Our analysis is based on the…
Scars of the Wigner function
Fabricio Toscano, Marcus A. M. de Aguiar, Alfredo M. Ozorio de Almeida
We propose a picture of Wigner function scars as a sequence of concentric rings along a two-dimensional surface inside a periodic orbit. This is verified for a two-dimensional plan…
