Nonlinear Dynamical Equation for Irreversible, Steepest-Entropy-Ascent Relaxation to Stable Equilibrium

Gian Paolo Beretta

We discuss the structure and main features of the nonlinear evolution equation proposed by this author as the fundamental dynamical law within the framework of Quantum Thermodynami…

LDPC codes from Singer cycles

L. Giuzzi, A. Sonnino

The main goal of coding theory is to devise efficient systems to exploit the full capacity of a communication channel, thus achieving an arbitrarily small error probability. Low De…

Evidence For The Production Of Slow Antiprotonic Hydrogen In Vacuum

N. Zurlo, M. Amoretti, C. Amsler +28

We present evidence showing how antiprotonic hydrogen, the quasistable antiproton-proton (pbar-p) bound system, has been synthesized following the interaction of antiprotons with t…

Parametric Frequency Conversion of Short Optical Pulses Controlled by a CW Background

Matteo Conforti, Fabio Baronio, Antonio Degasperis +1

We predict that parametric sum-frequency generation of an ultra-short pulse may result from the mixing of an ultra-short optical pulse with a quasi-continuous wave control. We anal…

Orthogonal arrays from Hermitian varieties

A. Aguglia, L. Giuzzi

An orthogonal array OA(q^{2n-1},q^{2n-2}, q,2) is constructed from the action of a subset of PGL(n+1,q^2) on some non--degenerate Hermitian varieties in PG(n,q^2). It is also shown…

Hyperbolic Balance Laws with a Non Local Source

Rinaldo M. Colombo, Graziano Guerra

This paper is devoted to hyperbolic systems of balance laws with non local source terms. The existence, uniqueness and Lipschitz dependence proved here comprise previous results in…

On the Stability Functional for Conservation Laws

Rinaldo M. Colombo, Graziano Guerra

This note is devoted to the explicit construction of a functional defined on all pairs of $\L1$ functions with small total variation, which is equivalent to the $\L1$ distance and…

Quantum thermodynamic Carnot and Otto-like cycles for a two-level system

Gian Paolo Beretta

From the thermodynamic equilibrium properties of a two-level system with variable energy-level gap , and a careful distinction between the Gibbs relation …

Thermo-mechanical behavior of surface acoustic waves in ordered arrays of nanodisks studied by near infrared pump-probe diffraction experiments

C. Giannetti, B. Revaz, F. Banfi +10

The ultrafast thermal and mechanical dynamics of a two-dimensional lattice of metallic nano-disks has been studied by near infrared pump-probe diffraction measurements, over a temp…
