Unitary Evolution on a Phase Space with Power of Two Discretization
E. G. Floratos, S. Nicolis
We construct quantum evolution operators on the space of states, that realize the metaplectic representation of the modular group SL(2,Z_2^n). This representation acts in a natural…
Dynamical Upper Bounds for the Fibonacci Hamiltonian
David Damanik, Serguei Tcheremchantsev
We consider transport exponents associated with the dynamics of a wavepacket in a discrete one-dimensional quantum system and develop a general method for proving upper bounds for…
On the Potential of the Excluded Volume and Auto-Correlation as Neuromorphometric Descriptors
L. da F. Costa, M. S. Barbosa, V. Coupez
This work investigates at what degree two neuromorphometric measurements, namely the autocorrelation and the excluded volume of a neuronal cell can influence the characterization a…
On ergodic theorems for free group actions on noncommutative spaces
Claire Anantharaman-Delaroche
We extend in a noncommutative setting the individual ergodic theorem of Nevo and Stein concerning measure preserving actions of free groups and averages on spheres of even…
