Spectral gap and the exponential localization in general one-particle systems
Tomotaka Kuwahara
We investigate the relationship between the spectral gap delta E_0 and the localization length xi in general one-particle systems. A relationship for many-body systems between the…

Role of external fields in enhancing long-distance entanglement at finite temperatures
Tomotaka Kuwahara
We investigate the end-to-end entanglement of a general XYZ-spin chain at the non-zero temperatures. The entanglement usually vanishes at a certain critical temperature , but…
