Homogeneous populations of oscillators have recently been shown to exhibit stable coexistence
of coherent and incoherent regions. Generalizing the concept of chimera states to the context of order-di...
Asymptotic analysis of stresses near a crack tip in a two dimensional colloidal packing saturated with liquid
Asymptotic analysis of stresses two dimensional colloidal
2010/11/24
The consolidation of colloidal particles in drying colloidal dispersions is in-uenced by various factors such as particle size and shape, and inter-particle potential. The capillary pressure induced b...
Atomistic theory of spin relaxation in self-assembled In$_{1-x}$Ga$_x$As/GaAs quantum dots at zero magnetic field
Atomistic theory spin relaxation zero magnetic field
2010/11/25
We present full atomistic calculations of the spin-flip time (T1) of electrons and holes mediated by acoustic phonons in self-assembled In1−xGaxAs/GaAs quantum dots at zero magnetic field. At lo...
An One Dimensional Adiabatic Model for Fusion Involving Loosely Bound and Halo Nuclei with Heavy Targets
One Dimensional Adiabatic Model Fusion Involving Loosely Bound Halo Nuclei Heavy Targets
2011/1/7
An one dimensional adiabatic model has been proposed for fusion of loosely bound and halo light
nuclei with various heavy targets. It is shown that fusion cross sections at near and sub-barrier energ...

Robust Level Coincidences Subband Structure of Quasi 2D Systems
2010/11/24
Recently, level crossings in the energy bands of crystals have been identified as a key signature for topological phase transitions. In general, three independent parameters must be tuned appropriatel...
Spin canting as a result of the competition between stripes and spirals in cuprates
Spin canting spirals in cuprates
2010/11/24
Based on the extended Hubbard model we calculate the energy of stripe and spiral ground states.
We find that uniform spirals get favored by a large t′/t ratio but are unstable at small doping towards...
We investigate the constraints on the superfluid fraction of an amorphous solid following from
an upper bound derived by Leggett. In order to accomplish this, we use as input density profiles generat...
We investigate the effects of a trapping space-dependent potential on the low-temperature quasilong-range order phase of two-dimensional particle systems with a relevant U(1) symmetry, such as quantum...
Grey solitons in a strongly interacting superfluid Fermi Gas
Grey solitons strongly interacting superfluid Fermi Gas
2010/11/24
The Bardeen-Cooper-Schrieffer to Bose-Einstein condensate (BCS to BEC) crossover problem is
solved for stationary grey solitons via the Boguliubov-de Gennes equations at zero temperature.
These cros...
On a microcanonical relation between continuous and discrete spin models
microcanonical relation ontinuous discrete spin models
2010/11/24
A relation between a class of stationary points of the energy landscape of continuous spin mod-
els on a lattice and the configurations of a Ising model defined on the same lattice suggests an approx...
Lifshitz transition in two-dimensional spin-density wave models
Lifshitz transition two-dimensional spin-density wave models
2010/11/23
We argue that both pocket-disappearing and neck-disrupting types of Lifshitz transitions can be
realized in two-dimensional spin-density wave models for underdoped cuprates, and study both
types of ...
Striking Roles for Spin Degrees of Freedom in the Second Landau Level
Spin Degrees Second Landau Level
2010/11/23
The spin degree of freedom in quantum phases of the second Landau level is probed by resonant light scattering.The long wavelength spin wave mode, which monitors the degree of spin polarization, is at...
Universal contact of strongly interacting fermions at finite temperatures
Universal contact strongly interacting fermions finite temperatures
2010/11/23
The recently discovered universal thermodynamic behaviour of dilute, strongly interacting Fermi
gases also implies a universal structure in the many-body pair-correlation function at short distances,...
We analyze a model of mutually-propelled laments suspended in a two-dimensional solvent. The
system undergoes a mean- eld isotropic-nematic transition for large enough lament concentrations and the...

Spin-dependent electronic hybridization carbon nanotubes
2010/11/24
We demonstrate single electron addition to different strands of a carbon nanotube rope. Anticrossings of anomalous conductance peaks occur in quantum transport measurements through the parallel quantu...
