"Novel, Collective Insulating Phase in 2D Superconductors in High Magnetic Fields"

Sambandamurhy Ganapathy , Magnet Lab, Tallahassee and Princeton University
[Host: Jongsoo Yoon]
Superconductor-insulator transition (SIT) in 2D films has been an active area in condensed matter physics research. The reason is the continuing theoretical focus to understand zero temperature quantum phase transitions (QPT) and the relative experimental ease with which QPT can be tuned successfully in 2D films. We present results from our study of the magnetic field (B)-tuned SIT in amorphous indium oxide films. We present three experimental evidences that suggest that a novel, collective insulating state emerges in the B-induced insulating phase. We argue that our results lend support to the central assumption of the QPT approach.
