CCPQ News: June 2014

CCPQ is a major sponsor of AttoFEL 2014: Free Electron Lasers and Attosecond Light Sources: portals to ultrfast dynamics AMO systems (30 June - 2 July 2014 at UCL.

Ultra-Short and Intense Laser pulses offer the means to observe, control and probe multi-electron effects during ionization and break-up of strongly-driven atoms and molecules. Moreover, Free Electron Laser facilities is a route to delivering XUV and X-ray pulses with intensities orders of magnitude larger than those provided by conventional synchrotron radiation sources. Ultra-fast and intense X-ray pulses open-up new horizons for probing and controlling the attosecond motion of inner-shell electrons in multi-photon multi-ionization processes.

This conference aims to bring together theorists from the FEL and Attosecond-Strong Field Science communities to discuss and present recent advances in theoretical techniques developed to tackle multi-electron effects in ionization of atoms and molecules. Another goal of this meeting is to draw together theorists and experimentalists in order to identify the most interesting challenges that both communities will face in the future.

The CCPQ Workshop Windsor 2013: Dynamics of Complex Quantum Systems (5-8 August at Cumberland Lodge, Windsor Great Park) brings together UK theory and experimental groups involved in realising, simulating and modelling the dynamics of a variety of complex quantum systems. The meeting is aimed at discussing both new mathematical and computational methods, as well as new experimental applications/phenomena/physics at a level suitable for postgraduate students in the field.

Topics of interest include, but are not limited to: optical lattices, microtraps, coupled-cavity arrays, phase transitions, chaos, coherence and entanglement, interferometry and atom optics, superfluidity, non-equilibrium dynamics, spinor and exotic condensates, quantum information applications, experimental perspectives.This year there will be special sessions on numerical simulation of strongly correlated systems including tensor network methods, environment engineering for quantum computation, cold atoms for quantum simulations and novel architectures for quantum computation and simulation.

CCPQ is supporting both the Institute of Physics Atomic and Molecular Interactions Group Spring Meeting (20-21 March, National University of Ireland, Maynooth, Ireland) and the UK Positron Workshop (27 March, Stranmillis College, Belfast).

CCPQ News: July 2012

Lecturer in the Centre for Theoretical Atomic, Molecular and Optical Physics, School of Mathematics and Physics, Queen's University Belfast (Ref. 12/102139) At least one and possibly more positions are available within the Centre for Theoretical Atomic, Molecular and Optical Physics (CTAMOP). Successful candidates will be expected to undertake research in either Quantum Information Processing or Strong-Field AMO Physics, and to contribute to teaching in Applied Mathematics and Theoretical Physics. In addition, the successful candidate will be expected to undertake administrative duties as assigned.

Quantum Information Processing Theory. The current activities of the group working on Quantum Technologies in CTAMOP include the investigation of mesoscopic quantumness in open systems (ultracold atoms, quantum spin networks and mechanical systems at the quantum level), quantum control in hybrid systems, quantum thermodynamics and foundations of quantum mechanics, and the theory of quantum correlations. The group, whose current funding includes support from the UK EPSRC, the European Union, the Alexander von Humboldt Stiftung and the Royal Commission for the Exhibition of 1851, has an internationally leading profile and a vast network of collaborations with premier experimental and theoretical teams working in the fields of Quantum Information, Quantum Optics, and (Ultra)Cold Atom Physics.

Theory of Strong-Field Atomic, Molecular and Optical Physics. Present research interests focus on gaining accurate multi-electron solutions of the time-dependent Schroedinger equation for few- and many-electron atoms in intense short-pulse laser fields. World-leading computational codes, developed within CTAMOP, include the HELIUM code for the helium atom in intense light fields, the R-matrix Floquet (RMF) codes for general atoms in long laser pulses and the R-matrix with Time dependence (RMT) code for general atoms in ultra-short light pulses. This ab-initio work effectively and efficiently harnesses the most powerful supercomputers available. This has made possible scientific discovery in advance of laboratory experiment and has led to a record of sustained funding by EPSRC and the European Union.

Many congratulations to Stan Scott and Penny Scott (Queen's University, Belfast), Liviu Ixaru (Horia Hulubei National Institute of Physics and Nuclear Engineering POB MG-6, Bucharest) and Christophe Denis (University Pierre et Marie Curie-Paris 6) on being awarded the UK Research Councils' HEC Strategy Committee HPC Prize 2006 for machine utilization, for work on the fast computation of Slater integrals. The research was focused on improving a suite of two-dimensional R-matrix propagation programs aimed at creating virtual experiments on HPC and Grid architectures to study electron scattering from H-like atoms and ions at intermediate energies. The resulting algorithms are embodied in a new computational strategy that is more accurate and is between one and two orders of magnitude faster than the original implementation. By further exploiting parallelism on HPCx the resulting implementation is up to 350 times faster than the original and 25 times less costly.

Following the successful April 2006 CCP2 workshop on explicitly correlated wavefunctions, we would like to remind readers that a book of conference proceedings is available.
