Thermal Fluctuation Statistics in a Molecular Motor Described by a Multidimensional Master Equation
K. J. Challis, M. W. Jack
We present a theoretical investigation of thermal fluctuation statistics in a molecular motor. Energy transfer in the motor is described using a multidimensional discrete master eq…
A Tight-Binding Approach to Overdamped Brownian Motion on a Multidimensional Tilted Periodic Potential
K. J. Challis, Michael W. Jack
We present a theoretical treatment of overdamped Brownian motion on a multidimensional tilted periodic potential that is analogous to the tight-binding model of quantum mechanics.…
Scattering Resonances in a Degenerate Fermi Gas
K. J. Challis, N. Nygaard, K. Mølmer
We consider elastic single-particle scattering from a one-dimensional two-component trapped superfluid Fermi gas when the incoming projectile particle is identical to one of the co…
Power-law behavior in the quantum-resonant evolution of the delta-kicked accelerator
P. L. Halkyard, M. Saunders, S. A. Gardiner +1
We consider the atom-optical delta-kicked accelerator when the initial momentum distribution is symmetric. We demonstrate the existence of quantum-resonant dynamics, and derive ana…
Fractional resonances in the atom-optical delta-kicked accelerator
M. Saunders, P. L. Halkyard, S. A. Gardiner +1
We consider resonant dynamics in a dilute atomic gas falling under gravity through a periodically pulsed standing-wave laser field. Our numerical calculations are based on a Monte…
The manifestation of quantum resonances and antiresonances in a finite temperature dilute atomic gas
M. Saunders, P. L. Halkyard, K. J. Challis +1
We investigate the effect of temperature on resonant and antiresonant dynamics in a dilute atomic gas kicked periodically by a standing wave laser field. Our numerical calculations…
