How to build a quantum Newton’s cradle

A quantum analogue of the popular “Newton’s cradle” toy has been proposed by a duo of physicists in Italy. Like momentum transferred in the toy, the team argues that it should be possible to achieve the nearly perfect transmission of … Read the rest

Newton cradle

Newton’s cradle (Fig. 1) is a valuable paradigm of how physical mechanisms are concealed into nature. It is a device based on classical mechanics that demonstrates the conservation of momentum and energy. On the other hand, Quantum Mechanics has been … Read the rest

Anomalous Heat Transport in Low Dimensions

Many phenomena in nature occur under nonequilibrium stationary conditions. For instance, an electric current is obtained by applying an electric field along a conductor or heat is transported when a temperature gradient is established between two boundaries of a material.

Statistical mechanics has been proven to be successful at describing physical systems at thermodynamic equilibrium.  Since most natural phenomena occur in nonequilibrium conditions, … Read the rest

Molecole magnetiche su grafene per la spintronica

Una ricerca, svolta in collaborazione fra fisici e chimici italiani, tedeschi e spagnoli, mostra che è possibile realizzare nano-sistemi ibridi depositando magneti molecolari su grafene. L’interazione fra gli spin dei magneti molecolari e il gas bidimensionale di elettroni del grafene … Read the rest

Film magnetici con domini a strisce

Le prime osservazioni di domini a strisce in film magnetici di FeNi risalgono agli anni “60. Le strisce si osservano a rimanenza (cioè in assenza di campo magnetico) e presentano una peculiare proprietà: il loro asse è orientato lungo la … Read the rest

Thermal convection in granular gases

A recent experiment, published in Phys. Rev. Lett. 117, 098006, 2016 shows thermal convection in a granular gas with small gravity. The convection pattern is induced by combination of vertical gravity and a horizontal thermal gradient due to energy dissipation … Read the rest

Quasi 2D granular dynamics

4000 spheres of steel (diameter 2mm) are deposited on a horizontal rough plate (200mm diameter, only a square 100mm X 100mm is shown) and are put in motion by vertical vibration of the plate (sinusoidal shaking, amplitude 0.7mm, frequency 200Hz). … Read the rest

Granular Phases

Steel spheres move on a plate. The “thermostat ” is a vibrating wall, following a sine law with frequency 20 Hz . Weak gravity (the plate has a small angle of inclination) draws the spheres toward the vibrating wall. In … Read the rest
