Time Operators and Time Crystals
K. Nakatsugawa, T. Fujii, A. Saxena +1
We investigate time operators in the context of quantum time crystals in ring systems. A generalized commutation relation called the generalized weak Weyl relation is used to deriv…

Possibility of Macroscopic resonant Tunneling near the Superconductor- Insulator Transition in YBaCuO Thin Films
S. Tanda, K. Kagawa, T. Maeno +4
Experimental results of I-V characteristics near the superconductor-insulator transition observed for disorder-tuned YBaCuO thinfilms are presented. The I-V characteristics exibit…
