Adaptive Quantum Optics with Spatially Entangled Photon Pairs

, 2018
Light shaping facilitates the preparation and detection of optical states and underlies many applications in communications, computing, and imaging. In this Letter, we generalize light shaping to the quantum domain.

Jahn-Teller like origin of the tetragonal distortion in disordered Fe-Pd magnetic shape memory alloys

, 2008
The electronic structure and magnetic properties of disordered Fe$_{x}$Pd$_{100-x}$ alloys $(50 < x < 85)$ are investigated in the framework of density functional theory using the full potential local orbital method (FPLO).

A finite element method for thermo-mechanical coupling analysis of shape memory alloys [PDF]

, 2013
Due to strong thermo-mechanical coupling in shape memory alloys (SMAs), heat generation/absorption during forward/reverse phase transformation can cause temperature variations in the material; influencing its mechanical behaviour.

Self-Excited Multifractal Dynamics

, 2011
We introduce the self-excited multifractal (SEMF) model, defined such that the amplitudes of the increments of the process are expressed as exponentials of a long memory of past increments.

Thermomechanical characterisation of a shape memory alloy for numerical modeling of its actuation response

Materials Research Express
Shape memory alloys (SMA) show the exceptional phenomena of shape memory effect, which is particularly interesting for an active functionalisation of lightweight structures and thus for the realisation of smart structures.

Fabrication and characterization of shape memory composite with layer by layer method

Cailiao gongcheng
Due to the its appropriate glass transition temperature（Tg）， a kind of carbon reinforced carbon-reinforced composite with exhibiting a shape memory effect is successfully fabricated using a layer-by-layer method. A thermoplastic polymer with a relatively

The Kovacs effect in model glasses

, 2003
We discuss the `memory effect' discovered in the 60's by Kovacs in temperature shift experiments on glassy polymers, where the volume (or energy) displays a non monotonous time behaviour.
