Quantum criticality at the superconductor-insulator transition revealed by specific heat measurements
To detect thermodynamic signatures of quantum fluctuations for quantum phase transitions is challenging. Here, Poranet al. report a significant increase in the specific heat when the thickness of granular Pb films approaches a superconductor-insulator transition.
