Mechanism of Hollow Nanoparticle Formation Due to Shape Fluctuations
Hollow Nanoparticle Formation Shape Fluctuations
2015/10/16
Shape fluctuations in nanoparticles strongly influence their stability. Here, we introduce a quantitative model of such shape fluctuations and apply this model to the important case of Pt-shell/transi...
The attractor mechanism in Gauss-Bonnet gravity
A black hole gravitational coupling system the second derivative
2014/12/20
We study extremal black hole solutions of D = 5 Gauss-Bonnet gravity coupled to a system of gauge and scalar fields. As in Einstein gravity, we find that the values of the scalar fields on the horizon...
Underlying Mechanism for the Giant Isochoric Compressibility of Solid 4He: Superclimb of Dislocations
Solid super fluid transportation such as volume compressibility vic glass electrode
2014/12/19
In the experiment on superfluid transport in solid 4He [Phys. Rev. Lett. 100, 235301 (2008)], Ray and Hallock observed an anomalously large isochoric compressibility: the supersolid samples demonstrat...
A Fully Anisotropic Mechanism for Formation of Trapped Surfaces in Vacuum
A Fully Anisotropic Mechanis Trapped Surfaces Vacuum
2014/4/3
In collaboration with I. Rodnianski and J. Luk we extend considerably the result of Christodoulou on the dynamic formation of trapped surfaces in vacuum by allowing characteristic initial data which a...

Mechanism Stepped Leaders Discharge Model Plasma Physics
2011/8/5
Abstract: We construct a one-dimensional model for the stepped leader in the filamental discharge by simplifying an electric-circuit model of discharge. We find that the leader of the discharge moves ...
Uncertainties in nuclear transition matrix elements for neutrinoless $ββ$ decay II: the heavy Majorana neutrino mass mechanism
matrix elements neutrino mass mechanism
2011/7/20
Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the unc...
On the Mechanism of Roe-type Schemes for All-Speed Flows
Roe-type scheme all-speed flows preconditioning checkerboard pressure-velocity decoupling asymptotic analysis global cut-off strategy
2011/8/17
Abstract: In recent years, Roe-type schemes based on different ideas have been developed for all-speed flows, such as the preconditioned Roe, the All-Speed Roe, Thornber's modified Roe and the LM-Roe ...
A New Mechanism for Gauging a Theory
Gauging, Fibrations M-theory High Energy Physics - Theory
2011/10/8
Abstract: We provide a mechanism of gauging a theory based on a particular way to embed a theory on a target space such that a nontrivial fibration is produced. A connection over a nontrivial fibratio...
Mechanism of delayed double ionization in a strong laser field
Centre de Physique Theoriqu Georgia Institute of Technology
2011/8/4
Abstract: When intense laser pulses release correlated electrons, the time delay between the ionizations may last more than one laser cycle. We show that this "Recollision-Excitation with Subsequent I...
Quantum Zeno-based control mechanism for molecular fragmentation
Quantum Zeno-based molecular fragmentation mechanism
2011/9/14
Within a scenario grounded on the quantum Zeno effect, a quantum control mechanism is proposed for molecular fragmentation processes. In particular, we focus on the van der Waals Ne-Br2 complex, which...
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse orange 11 doped in PMMA
hypothesis self-healing
2011/9/1
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in PMMA is not due to dye diffusion – a common phenomenon observed in many dye-doped polymers. The change in linear a...
Possible mechanism responsible for observed impurity outward flow under radio frequency heating
Possible mechanism radio frequency heating
2011/8/26
The effect of poloidal asymmetry of impurities on impurity transport driven by electrostatic turbulence in tokamak plasmas is analyzed. It is found that in
the presence of in-out asymmetric impurity ...

Vortex content of calorons and deconfinement mechanism
Vortex content calorons deconfinement mechanism
2011/1/7
We reveal the center vortex content of SU(2) calorons and ensembles of them. While one part of the vortex connects the constituent dyons of a single caloron, another part is predominantly spatial and ...
