Research Interests

• Dynamics of quantum gases and other quantum many-body systems
  • Interplay of quantum and thermal fluctuations -- and especially: how to simulate such a case?
  • Solitons and other nonequilibrium collective phenomena
  • Colliding BECs
  • Dynamics of evaporative cooling, condensate formation
  • Supersonic effects in BECs, friction below the superfluid critical velocity
  • Quantum droplets
  • Effects beyond Bogoliubov linearisation
  • Nonlocal interparticle correlations
  • Thermodynamics of 1D Bose gas
  • Gases of fermionic dipoles
• Methods for simulation of the quantum dynamics of interacting many body systems
  • Phase space stochastic methods (Positive-P, Wigner, Gauge-P, ...)
    • Development of improved simulation techniques - distributions, algorithms
    • Stochastic simulation of Bogliubov dynamics
  • Classical field methods (SGPE,truncated Wigner,...)
    • Regimes of applicability
    • Extension to include quantum fluctuations
• Fundamental aspects of quantum mechanics
• Macroscopic violation of Bell inequalities (states that would display EPR correlations but robust to single-particle decoherence)
• Is experimental testing of the Everett interpretation of quantum mechanics possible?
• Strength testing of wooden power poles (see Deuar Pty. Ltd.)
  • Predictions of power pole breaking strength based on measurements of bending under test loads.
  • Development of equipment for applying test loads to standing power poles.
• Quantum information theory
• Dynamics of asteroids in the Solar System
