    Superfluid 3He

    At ambient pressure, 3He does not solidify, even down to termpatures near absolute zero. Its behaviour is dominated by quantum mechanical effects, and it is arguably the most complex and remarkable fluid we know of. John Davis has used transverse sound measurements to determine the energy and Zeeman splitting of excited Cooper pair sates in the superfluid phase of 3He.

    Quantum Dots in Optical Microcavities

    Whispering Gallery Modes are a wave interference effect in circular geometries. The name was coined by Lord Rayleigh to describe the acoustic effects in St. Paul's cathedral, London. The same phenomena occur in optical resonators. The animation above shows a simulation of the electric field of a low-angular number (l=6) whispering gallery mode propagating in a microsphere.

    Quantum Cellular Automata

    Robert Wolkow and coworkers at NINT have demonstrated that single silicon atoms on a surface can act as quantum dots. This may allow for the implementation of an extremely low power computer architecture in which electronic configuration rather than current is propagated.

    Unzipping Proteins

    Michael Woodside's group studies how single biological molecules like nucleic acids and proteins respond when mechanical forces are applied across the molecules. Optical tweezers are used to apply force to the ends of a molecule, causing it to unfold and refold reversibly. The resulting trajectories of the molecule and their dependence on the applied force yield important insight into the thermodynamic and kinetic properties of structure formation in biomolecules.

    Tubulin

    Tubulin is the target for numerous small molecule ligands which alter microtubule dynamics leading to cell cycle arrest and apoptosis. Many of these ligands are currently used clinically for the treatment of several types of cancer. Unfortunately, serious side effects always accompany chemotherapy since these drugs bind to tubulin indiscriminately, leading to the death of both cancerous and healthy cells. However, the existence and distribution of divergent tubulin isoforms provide a platform upon which we may build novel chemotherapeutic drugs that can differentiate between different cell types and therefore reduce undesirable side effects.

    Spin Transfer in Coupled Chains

    The manner in which spin-polarized electrons interact with a magnetized thin film is currently described by a semi-classical approach. This in turn provides our present understanding of the spin transfer, or spin torque phenomenon. However, spin is an intrinsically quantum-mechanical quantity. Here, we make the first strides towards a fully quantum-mechanical description of spin transfer through spin currents interacting with a Heisenberg-coupled spin chain.
