Ortnogonal-to-unitary ensemble crossover in the electronic specific heat of metal namoclusters

Анотація:

We present a theoretical and experimental study on the influence of a magnetic field on the energy-level statistics in metal nanoparticles. Based on the random-matrix theory, a gradual field-in-duced crossover behavior is predicted from the orthogonal to the unitary ensemble. Experimental data of the electronic specific heat of metal nanoparticles for different fields in the quantum-size temperature regime compare favourably with these theoretical (analytical) predictions.
