Coherent Mott Excitations Captured on the Timescale of Electron Correlations (2009)
Wall, S., Brida, D., Clark, S. R., Ehrke, H. P., Jaksch, D., Ardavan, A., ...
By using nearly-single-cycle optical pulses in the near infrared, we measure the time-dependent optical properties of the Mott insulator ET-F2TCNQ after prompt photo-excitation. We observe a rapid...

The observed spectra of 9 pulsars for which multiwavelength data are available from radio to $X$- or $\gamma$-ray bands (Crab, Vela, Geminga, B0656+14, B1055-52, B1509-58, B1706-44, B1929+10, and...
Quantum computing with an electron spin ensemble (2009)
Wesenberg, J. H., Ardavan, A., Briggs, G. A. D., Morton, J. J. L., Schoelkopf, R. J., Schuster, D. I., ...
We propose to encode a register of quantum bits in different collective electron spin wave excitations in a solid medium. Coupling to spins is enabled by locating them in the vicinity of a...
Electronic transport characterization of Sc@C82 single-wall carbon nanotube peapods (2008)
Cantone, A. L., Buitelaar, M. R., Smith, C. G., Anderson, D., Jones, G. A. C., Chorley, S. J., ...
We present electrical transport and Raman measurements on individual single-wall carbon nanotubes filled with the paramagnetic metallofullerene Sc@C_82. We find nearly all devices to be metallic...
Pauli spin blockade in carbon nanotube double quantum dots (2008)
Buitelaar, M. R., Fransson, J., Cantone, A. L., Smith, C. G., Anderson, D., Jones, G. A. C., ...
We report Pauli spin blockade in an impurity defined carbon nanotube double quantum dot. We observe a pronounced current suppression for negative source-drain bias voltages which is investigated for...
Dynamics of paramagnetic metallofullerenes in carbon nanotube peapods (2008)
Warner, JH, Watt, AAR, Ge, L, Porfyrakis, K, Akachi, T, Okimoto, H, ...
We filled SWNTs with the paramagnetic fullerene Sc@C-82 to form peapods. The interfullerene 1D packing distance measured using TEM is d = 1.1 +/- 0.02 nm. The SC@C-82 in SWNT peapods continuously...
Analytis, J G, Ardavan, A, Blundell, S J, Owen, R L, Garman, E F, Jeynes, C, ...
We have introduced defects into clean samples of the organic superconductor kappa-(BEDT- TTF)(2)Cu(SCN)(2) in order to determine their effect on the temperature dependence of the interlayer...
Coherence of Spin Qubits in Silicon (2005)
Tyryshkin, A. M., Morton, J. J. L., Benjamin, S. C., Ardavan, A., Briggs, G. A. D., Ager, J. W., ...
Given the effectiveness of semiconductor devices for classical computation one is naturally led to consider semiconductor systems for solid state quantum information processing. Semiconductors are...
