Angular dependence of upper critical field in two-band Ginzburg-Landau theory
(Elsevier B.V., 2007)Generalization of two-band Ginzburg-Landau (GL) theory to the case of anisotropic mass is presented. The temperature dependence of the anisotropy parameter of upper critical field γc 2 (T) = Hc 2∥ (T) / Hc 2⊥ (T) and angular ... -
Anharmonic line shift and linewidth of the Raman modes in TlInS2 layered crystals
(John Wiley & Sons Ltd., 2004)The temperature dependence of the unpolarized Raman spectra from TlInS 2 layered crystal was measured between 10 and 300 K. The analysis of the experimental data showed that the temperature dependences of wavenumbers and ... -
Anisotropic electronic, mechanical, and optical properties of monolayer WTe2
(American Institute of Physics Inc., 2016)Using first-principles calculations, we investigate the electronic, mechanical, and optical properties of monolayer WTe2. Atomic structure and ground state properties of monolayer WTe2 (Td phase) are anisotropic which are ... -
Anisotropic stimulated emission from aligned CdSe/CdS dot-in-rods
(IEEE, 2014-10)Anisotropic optical properties of CdSe/CdS dot-in-rods loaded in a capillary tube are demonstrated, suggesting nanorods' alignment with a microfluidic approach. Polarized emissions from photoluminescence and whispering ... -
Anisotropy sensitivity of an acoustic lens with slit aperture
(IEEE, 1993)A conventional spherical acoustic lens is modified by restricting its aperture in the form of a slit to provide directional sensitivity. The spacing between the two parallel absorbing sheets forming the slit is adjustable ... -
Bio-inspired hierarchically structured polymer fibers for anisotropic non-wetting surfaces
(Royal Society of Chemistry, 2017)We demonstrate a rice leaf-like hierarchically textured polymer fiber array for anisotropic non-wetting surfaces. To provide superhydrophobicity in addition to the anisotropic behavior, fiber surfaces are spray coated with ... -
Density profile of a Bose-Einstein condensate inside a pancake-shaped trap: Observational consequences of the dimensional cross-over in the scattering properties
(Elsevier Science B.V., 2002)It is theoretically well known that two-dimensionality of the scattering events in a Bose-Einstein condensate introduces a logarithmic dependence on density in the coupling constant entering a mean-field theory of the ... -
Effects of anisotropy on the critical temperature in layered nonadiabatic superconductors
(Elsevier Science B.V., 2003)The generalized anisotropic Eliashberg theory is employed to study the critical temperature of layered nonadiabatic superconductors where the relevant phonon energy is comparable to the Fermi energy. We consider a ... -
Free expansion of two-dimensional condensates with a vortex
(Institute of Physics Publishing, 2003)We study the free expansion of a pancake-shaped Bose-condensed gas, which is initially trapped under harmonic confinement and containing a vortex at its centre. In the case of a radial expansion holding the axial confinement ... -
Identification of materials with magnetic characteristics by neural networks
(2012)In industry, there is a need for remote sensing and autonomous method for the identification of the ferromagnetic materials used. The system is desired to have the characteristics of improved accuracy and low power ... -
Investigation of new two-dimensional materials derived from stanene
(Elsevier, 2017-09)In this study, we have explored new structures which are derived from stanene. In these new proposed structures, half of the Sn atoms, every other Sn atom in two-dimensional (2D) buckled hexagonal stanene structure, are ... -
Labyrinth based left-handed metamaterials and sub-wavelength focusing of electromagnetic waves
(SPIE, 2006)We propose and demonstrate a resonant structure that solves two major problems related to the split-ring resonator structure. These major problems may be stated as the bianisotropy and electric coupling to the magnetic ... -
Magnetic-field dependence of low-temperature mobility in quasi-one-dimensional electron systems
(Institute of Physics Publishing Ltd., 1994)We study the mobility of a quasi-one-dimensional (Q1D) electron system in the presence of an axial magnetic field at low temperatures. We consider the mobility limits for remote-impurity scattering, homogeneous-background ... -
Microfluidic methods in janus particle synthesis
(Dove Medical Press Ltd, 2022-09-19)Janus particles have been at the center of attention over the years due to their asymmetric nature that makes them superior in many ways to conventional monophase particles. Several techniques have been reported for the ... -
