THz-Frequency Modulation of the Hubbard U in an Organic Mott Insulator
R. Singla, G. Cotugno, S. Kaiser +10
We use midinfrared pulses with stable carrier-envelope phase offset to drive molecular vibrations in the charge transfer salt ET-F2TCNQ, a prototypical one-dimensional Mott insulat…
Pressure dependent relaxation in the photo-excited Mott insulator ETF2TCNQ: Influence of hopping and correlations on quasiparticle recombination rates
M. Mitrano, G. Cotugno, S. R. Clark +12
Femtosecond relaxation of photo-excited quasiparticles in the one dimensional Mott insulator ET-F2TCNQ are measured as a function of external pressure, which is used to tune the el…
Cupric chloride CuCl2 as an S=1/2 chain multiferroic
S. Seki, T. Kurumaji, S. Ishiwata +6
Magnetoelectric properties were investigated for an S=1/2 chain antiferromagnet CuCl2, which turns out to be the first example of non-chalcogen based spiral-spin induced multiferro…
Tuning of metal-insulator transition of two-dimensional electrons at parylene/SrTiO interface by electric field
H. Nakamura, H. Tomita, H. Akimoto +6
Electrostatic carrier doping using a field-effect-transistor structure is an intriguing approach to explore electronic phases by critical control of carrier concentration. We demon…
Suppression of rectification at metal-Mott-insulator interfaces
Kenji Yonemitsu, Nobuya Maeshima, Tatsuo Hasegawa
Charge transport through metal-Mott-insulator interfaces is studied and compared with that through metal-band-insulator interfaces. For band insulators, rectification has been know…
