Discover Magazine Names NYU Physics Finding One of Top Stories of 2009
The NYU team, led by Jasna Brujic, an assistant professor in NYU’s
Department of Physics, developed an innovative way to tabulate the
number of spheres-they created a method for determining how spheres
pack from inside the jar, making it easier to more accurately count
them.

Ultra-Fast Electrically Driven Single Spin Rotations
A single electron spin in an external magnetic field forms a two-level system that can be used to create a spin qubit. However, achieving fast single spin rotations, as would be required to control a spin qubit, is a major challenge. It is difficult to drive spin rotations on timescales that are faster than the spin dephasing time and to individually address a single spin on the nanometer scale. We have developed a new method for quantum control of single spins that does not involve conventional electron spin resonance (ESR).

Cell Motility Driven by Actin Polymerization: A New Proposed Mechanism
In designing new motile materials, much can be learned by studying the
physical mechanisms underlying cell crawling. One important form of
cell crawling is driven by self-assembly of the protein actin. In this
process, energy is supplied and various proteins cooperate to assemble

Origin of the Colossal Electromagnon in Multiferroic RMnO3
In multiferroic materials, where magnetism and ferroelectricity coexist, it is possible to excite mixed spin and lattice vibrations with electromagnetic waves called electromagnons. We find that the mechanism responsible for electromagnons is different from the one that couples static magnetism and ferroelectricity. Our results show how the strong coupling of spin and lattice excitations produce the colossal electromagnon observed in RMnO3. This mechanism can also exist in non-multiferroic materials.

Effect of Particle Additives on the Texture Evolution in Block Copolymer Blends
Block copolymer/nanoparticle (BCP/NP) composites have attracted
interest because of the unique opportunities for tuning the properties
of hybrid materials arising from the control of orientation and
location of particle fillers within the copolymer matrix. However,
quiescent organized block copolymer microstructures are not
macroscopically uniform but rather exhibit ‘polycrystal-type’ texture
with grain boundary defects that disrupt the long-range periodicity.

Genetically-Engineered Protein Materials and Self-Assembly : Video
The video describes the Montclare lab research efforts
to fabricate nano-scaled self-assembling proteins as materials. It focuses on
the use of bacteria as the synthetic powerhouse for soft materials synthesis and
features the self-assembly behavior of these biologically-inspired materials for
potential use in therapeutic delivery and regenerative medicine.

Imaging Quantum states of Bosonic atoms
By tuning the optical lattice
depth or the interaction between cold atoms, a weakly-interacting atomic
bosonic superfluid can be converted into a strongly correlated Mott insulator.
