Magnetism in Reduced Dimensions [PDF]

open access: yesComptes Rendus Physique, 2005
We propose a short overview of a few selected issues of magnetism in reduced dimensions, which are the most relevant to set the background for more specialized contributions to the present Special Issue. Magnetic anisotropy in reduced dimensions is discussed first, on a theoretical basis, then with experimental reports and views from surface to single ...

Orbital Order Melting at Reduced Dimensions

Nano Letters, 2022
The orbital degree of freedom, strongly coupled with the lattice and spin, is an important factor when designing correlated functions. Whether the long-range orbital order is stable at reduced dimensions and, if not, what the critical thickness is remains a tantalizing question.

REDUCING DIMENSION IN GLOBAL OPTIMIZATION

International Journal of Computational Methods, 2011
In this paper, we propose a very interesting idea in global optimization making it easer and a low-cost task. The main idea is to reduce the dimension of the optimization problem in hand to a mono-dimensional one using variables coding. At this level, the algorithm will look for the global optimum of a mono-dimensional cost function. The new algorithm

Persymmetric Adaptive Detection With Reduced-Dimension Approach

IEEE Signal Processing Letters, 2020
For target detection in Gaussian noise with unknown covariance matrix, usually sufficient training data are needed to form a nonsingular estimate of the noise covariance matrix. However sufficient training data could not be satisfied in practice.

Reduced dimension estimators in matched subspace detection

2016 8th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2016
The standard matched subspace detector is modified by replacing a full-rank oblique pseudoinverse with a reduced-dimension version that trades bias for variance. Minimization of the bias squared plus variance produces an order determination rule relating signal to noise ratio and noise gain.

Emergence of room-temperature ferroelectricity at reduced dimensions

Science, 2015
Thinning films induces ferroelectricity Thin ferroelectric films are needed in computers and medical devices. However, traditional ferroelectric films typically become less and less polarized the thinner the films become. Instead of using a good ferroelectric and making it thinner, Lee et al.

Reduced dimension image compression and its applications

Proceedings., International Conference on Image Processing, 2002
A key to successful image compression is a combination of (1) energy compaction by appropriate transform algorithms to exploit data redundancy, (2) judicious quantization of compressed transform coefficients, and (3) efficient entropy encoding that takes advantage of different symbol rates.

Microstrip dipole antenna with reduced dimensions with cutouts

2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018
This work briefly describes the development of radio-frequency systems. Using the electrodynamic design program Ansys HFSS, a standard design of a dipole antenna was developed on a dielectric substrate $\mathbf{\Phi}\mathbf{P}-4$ , whose shoulders are located on opposite sides of the substrate.

Interacting Electrons in Reduced Dimensions

1989
As its name suggests, the 1988 workshop on "Interacting Electrons in Reduced Dimen the wide variety of physical effects that are associated with (possibly sions" focused on strongly) correlated electrons interacting in quasi-one- and quasi-two-dimensional mate rials.
