Results are reported for H-alpha observations of a large sunspot group and measurements of the magnetic field strengths in the 6302-A Fe I and 6103-A Ca I lines. Analysis of all the observational data shows that (1) all centers of activity in the group are situated in regions of contact...
A system of two-dimensional electrons and holes ha s been investigated in a strong magnetic field, when it is sufficient to take into account only the ground Landau level. It has been shown that the interaction of electrons and holes can lead to an ordered state. In this problem, the ...
In other words, the surface system forms an independent two-dimensional superfluid that, at the zero-temperature limit, determines the thermo-mechanical properties of 3He. Confining a fermion gas at a low temperature to a high-purity two-dimensional solid-state system has led to the discovery ...
To approach this, we surveyed the structure of students’ mental models in the context of photons’ properties and behavior. We conducted a questionnaire study: 170 secondary school students completed a survey instrument adapted from the literature. Using exploratory factor analysis, the two factors ...
Two-dimensional (2D) materials have sparked intense interest among the scientific community owing to their extraordinary mechanical, optical, electronic, and thermal properties. In particular, the outstanding electronic and optical properties of 2D materials make them show great application potential in hig...
of field-induced chirality for a particular choice of model parameters5,6. However, the dependence of the field-induced chiral phase on the exchange couplings and on the DM interactions was not considered in detail. The calculations further seemed to indicate the presence of another magnetic phase...
By using a high quality Tl_2Ba_2Ca_2Cu_3O_(10) (Tl-2223) single crystal as an example, the magnetization vector was probed in the reversible region of highly anisotropic cuprate superconductors. For that, we have measured its components along and transverse to the applied magnetic field for...
Effects of a Tilted Magnetic Field on a Two-Dimensional Electron Gas n-type inverted silicon surfaces were studied to examine properties of a two-dimensional electron gas as well as those properties of silicon itself. The effect of a magnetic field tilted up to +/-90° from the normal to ...
In this work, based on explicit-ion and implicit-solvent formalisms, we develop a high-throughput computational framework to assess thousands of 2D electrode materials for LIB and supercapacitors. From the DFT-calculated single-Li (SL)-binding properties of a material, we devise four descriptors ...
These modalities rely on different contrast mechanisms and are often used simultaneously to provide complementary information on morphology, metabolism, and structural properties of the imaged tissue. The cornea, being a transparent tissue, rich in collagen and with several cellular layers, is well-...
