Quantum Levitation

2 Matthew Sullivan 2014 video

Superconductors can be engineered to act less like superconductors and more like perfect conductors, creating levitation above and suspension below magnetic tracks. Once relegated to research institutions, these materials can be made even at undergraduate institutions. They have uses beyond MagLev trains in high-power magnets and frictionless bearings.

University of Illinois at Urbana-Champaign

The authors made a video where two scientists are questioned by two cops about the appearances of a monster who scared people in public places. This fictional story is based on our study on bistable systems which has been recently published in Physical Review Letters. The actors include me, Dr. Louise Dyson and Prof. Alan McKane who are the other authors of the research.

Single DNA Molecule Trapped by Asymmetric Pulsed Electric Fields

The video shows the dynamics of T4 DNA (166kbp) trapped in colloidal crystal (black background) by 2D pulsed electric fields. The linear DNA molecule collides with lattice nanoparticle and forms a pulley structure. The mobility of the pivot segment is reduced by dielectrophoretic force when it is subjected to the non-uniform electric field at the contact zone of two colloidal particles, while two arms still shuttle through interstitial pores following the switching between electric fields. Ultimately, the DNA molecule is permanently stitched in the nanoporous structure and pulsed fields act as needles throughout the process.

Schallamach Waves on Adhesive Surfaces

9 Koushik Viswanathan 2014 video

Koushik Viswanathan
Purdue University

The video shows the development of a surface instability when a soft adhesive polymer is slid against a hard glass sphere. Contrary to how friction is usually perceived between two smooth surfaces, relative motion between these surfaces occurs only via the propagation of wave pulses consisting of trapped air pockets.

Cavity Cooling of a Silicon Nanoparticle

The animation of recorded data shows a nanoparticle traveling through the light field of an optical resonator. The refractive index of the moving particle modulates the intensity of the standing light wave. This time dependent optical potential leads to a reduction of the particle’s horizontal velocity while passing through.

Winding Up Bose-Einstein Condensate

13 Wojciech Zurek 2014

Bose-Einstein condensation in a toroidal trap. We study BEC formation using stochastic Gross-Pitaevskii equation in one dimension and plot local density of the condensate (represented by the radius) along the torus. Color encodes the phase of the BEC wavefunction. Initially random phases of BEC “beads” are smoothed out (seeding the transient solitons) resulting in a winding number (here W=1) and persistent flow in the BEC torus.
