#### Double quantum dot photoluminescence mediated by incoherent reversible energy transport

(2010)

We present a theoretical study of the stationary photoluminescence of two, direct-gap, semiconductor nanocrystals,
taking into account electronic excitation energy-transfer processes due to electrostatic interaction. ...

#### Inertial Effects in the Fractional Translational Brownian Motion in a Double-Well Potential

(2007)

The anomalous translational diffusion including inertial effects of nonlinear Brownian oscillators in a double well potential V(x)=ax2?2+bx4?4 is considered. An exact solution of the fractional Klein-Kramers (Fokker-Planck) ...

#### Superlattice structures observed in the extraordinary phase sequence and analyzed by the phenomenological Landau model and the partially molecular model.

(2013)

We draw several electric-field-temperature (E-T) phase diagrams with electric-field-induced birefringence contours in the nOHFBBB1M7 (n=10) and nOTBBB1M7 (n=11) (C11) mixture system by changing the C11 concentration ...

#### Spin-torque effects in thermally assisted magnetisation reversal: Method of statistical moments

(2013)

Thermal fluctuations of nanomagnets driven by spin-polarized currents are treated via the Landau-Lifshitz-Gilbert equation generalized to include both the random thermal noise field and the Slonczewski spin-transfer torque ...

#### X-ray diffraction study of ferroelectric and antiferroelectric liquid crystal mixtures exhibiting de Vries SmA∗-SmC∗ transitions

(2010)

In this Rapid Communication, results on smectic layer thickness, using synchrotron radiation x-ray diffraction,
for different mixtures of ferroelectric and antiferroelectric liquid crystals are given. We find that with ...

#### Inertial effects in the anomalous dielectric relaxation of rotators in space

(American Physical Society, 2002)

The linear dielectric response of an assembly of noninteracting linear (needlelike) dipole molecules (each of which is free to rotate in space) is evaluated in the context of fractional dynamics. The infinite hierarchy of ...

#### Nonlinear noninertial response of a quantum Brownian particle in a tilted periodic potential to a strong ac force as applied to a point Josephson junction

(2009)

The normal phase diffusion problem in magnetic resonance imaging (MRI) is treated by means of the Langevin equation for the phase variable using only the properties of the characteristic function of Gaussian random variables. ...

#### Biaxial order parameter in the homologous series of orthogonal bent-core smectic liquid crystals

(2013)

The fundamental parameter of the uniaxial liquid crystalline state that governs nearly all of its physical properties is the primary orientational order parameter (S) for the long axes of molecules with respect to the ...

#### Effect of cybotactic clusters on the elastic and flexoelectric properties of bent-core liquid crystals belonging to the same homologous series

(2013)

We report results of the splay (

) and bend (
K

) elastic constants and the effective flexoelectric coefficient
of three bent-core liquid crystals belonging to a homologous series of 4-cyanoresorcinol ...
