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...
Exact matrix product solutions in the Heisenberg picture of an open quantum spin chain (2009)
Clark, S. R., Prior, J., Hartmann, M. J., Jaksch, D., Plenio, M. B.
In recent work Hartmann et al [Phys. Rev. Lett. 102, 057202 (2009)] demonstrated that the classical simulation of the dynamics of open 1D quantum systems with matrix product algorithms can often be...
Adiabatic melting of two-component Mott-insulator states (2008)
Rodriguez, M., Clark, S. R., Jaksch, D.
We analyze the outcome of a Mott insulator to superfluid transition for a two-component Bose gas with two atoms per site in an optical lattice in the limit of slow ramping down the lattice potential....
Transport of strong-coupling polarons in optical lattices (2007)
Bruderer, M., Klein, A., Clark, S. R., Jaksch, D.
We study the transport of ultracold impurity atoms immersed in a Bose-Einstein condensate (BEC) and trapped in a tight optical lattice. Within the strong-coupling regime, we derive an extended...
Graph state generation with noisy mirror-inverting spin chains (2007)
Clark, S. R., Klein, A., Bruderer, M., Jaksch, D.
We investigate the influence of noise on a graph state generation scheme which exploits a mirror inverting spin chain. Within this scheme the spin chain is used repeatedly as an entanglement bus (EB)...
Fast initialization of a high-fidelity quantum register using optical superlattices (2007)
Vaucher, B., Clark, S. R., Dorner, U., Jaksch, D.
We propose a method for the fast generation of a quantum register of addressable qubits consisting of ultracold atoms stored in an optical lattice. Starting with a half filled lattice we remove every...
Griessner, A., Daley, A. J., Clark, S. R., Jaksch, D., Zoller, P.
We analyse a laser assisted sympathetic cooling scheme for atoms within the lowest Bloch band of an optical lattice. This scheme borrows ideas from sub-recoil laser cooling, implementing them in a...
RodrÃguez, M., Clark, S. R., Jaksch, D.
We propose the dynamical creation of twin Fock states, which exhibit Heisenberg limited interferometric phase sensitivities, in an optical lattice. In our scheme a two-component Mott insulator with...
Dark state cooling of atoms by superfluid immersion (2006)
Griessner, A., Daley, A. J., Clark, S. R., Jaksch, D., Zoller, P.
We propose and analyse a scheme to cool atoms in an optical lattice to ultra-low temperatures within a Bloch band, and away from commensurate filling. The protocol is inspired by ideas from dark...
We present a detailed analysis of the dynamical response of ultra-cold bosonic atoms in a one-dimensional optical lattice subjected to a periodic modulation of the lattice depth. Following the...
Numerical Analysis of Coherent Many-Body Currents in a Single Atom Transistor (2005)
Daley, A. J., Clark, S. R., Jaksch, D., Zoller, P.
We study the dynamics of many atoms in the recently proposed Single Atom Transistor setup [A. Micheli, A. J. Daley, D. Jaksch, and P. Zoller, Phys. Rev. Lett. 93, 140408 (2004)] using recently...
Efficient generation of graph states for quantum computation (2004)
Clark, S. R., Alves, C. Moura, Jaksch, D.
We present an entanglement generation scheme which allows arbitrary graph states to be efficiently created in a linear quantum register via an auxiliary entangling bus. The dynamics of the entangling...
Dynamics of the superfluid to Mott insulator transition in one dimension (2004)
We numerically study the superfluid to Mott insulator transition for bosonic atoms in a one dimensional lattice by exploiting a recently developed simulation method for strongly correlated systems....
Eastern Space and Missile Center (ESMC) Capability. (1998)
Clark,S. R., McLamb,F. Donald J.
The Eastern Space and Missile Center's Eastern Test Range includes all stations, ships, sites, ocean areas, and airspace necessary to conduct missile and space vehicle test and evaluation. This paper...
Simulation of a Paging Computer System (1972)
Boote, W. P., Clark, S. R., Rourke, T. A.
The operation of the Atlas computer at Manchester University is simulated using a next-event type of simulation model. The agreement between the simulated results and the real system is found to be...
An index directed compiler (1967)
This paper describes a system for discriminating between many possible combinations of conditions and invoking a routine to deal with them. It is illustrated with reference to a situation which may...
The Main Features of Atlas Autocode (1966)
Brooker, R. A., Rohl, J. S., Clark, S. R.
This paper describes the main features of an ALGOL-type compiler that has been used very successfully with the Manchester Atlas for over two years. Since we are dealing with a working system special...
Clark, S. R., Brody, J. S., Sidebottom, E.
The behaviour in vivo of tight and loose variants of murine melanoma cells is further characterized. In vitro clonal morphology is reproduced on a variety of substrates. Results suggest that repeated...
Cell fusion segregates progressive growth from metastasis.
Cell fusion has been used to analyse the genetic determinants of metastasis at the cellular level. Highly metastatic mouse melanoma cells were fused with diploid mouse lymphocytes and a range of...
