TL;DR: The onset of superconductivity in homogeneous ultrathin films is found to occur when their normal-state sheet resistance falls below a value close to h/4e/sup 2/, the quantum resistance for pairs, suggesting that in the T..-->..0 limit such films are either superconducting or insulating.

TL;DR: The application of the field-effect transistor principle to novel materials to achieve electrostatic doping is a relatively new research area as mentioned in this paper, which can in principle serve as a tool for studying quantum critical behavior, by permitting the ground state of a system to be tuned in a controlled fashion.

TL;DR: Two classes of theories explaining a nearly universal resistance threshold forsuperconductivity have emerged and both classes involve the quenching of thesequantum fluctuations.

TL;DR: In this paper, the authors link the physics of the superconductor-insulator transition in thin films to other systems believed to exhibit quantum phase transitions, such as high temperature superconductors, Josephson junction arrays, two-dimensional electron gases and various spin systems.

TL;DR: In this paper, the critical current of a thin film of the high-T c$ superconductor was found to be strongly suppressed by current flowing in the ferromagnetic film.
