Breathing distortions in the metallic, antiferromagnetic phase of LaNiO$_3$
SciPost Physics, 2018 I study the structural and magnetic instabilities in LaNiO$_3$ using density functional theory calculations. From the non-spin-polarized structural relaxations, I find that several structures with different Glazer tilts lie close in energy. The $Pnma$

Jahn-Teller distortion in Cs4C60 studied by vibrational spectroscopy [PDF]
, 2002 We have measured the infrared spectra of Cs(4)C(60) in the temperature range 220 - 450 K. Two anomalies in the low-frequency modes at 270 K and 400 K point to changes in molecular or crystal structure.

Analysis of Multi-Antenna GNSS Receiver Performance under Jamming Attacks
Sensors, 2016 Although antenna array-based Global Navigation Satellite System (GNSS) receivers can be used to mitigate both narrowband and wideband electronic interference sources, measurement distortions induced by array processing methods are not suitable for high ...

Generation of the rotating light fields under amplitude and phase distortions
EPJ Web of Conferences, 2017 The work contains study of the influence of amplitude and phase distortions on the generation of two-lobe light fields with the intensity distribution rotating under propagation. Spiral beams, as well as light fields formed on their basis, are considered

Megahertz-rate shock-wave distortion cancellation via phase conjugate digital in-line holography
Nature Communications, 2020 Shock-waves in explosive, supersonic or ionizing environments impart phase distortions to holographic imaging. Here, the authors report an ultra-high-speed phase conjugate digital in-line holography technique where a laser passes through the shock-wave ...

Mitigation of Fiber Nonlinearity Effects in Ultra High-Dense WDM System by Using Fractional Fourier Transform for 32 Channel System [PDF]
Engineering and Technology Journal, 2016 The optical signal is severely degraded when transmitted in the fiber due to both the linear and nonlinear distortions. It is well known that, the linear distortions in single mode fiber include chromatic dispersion (CD) and polarization-mode dispersion (

Parameters for Systems Exhibiting Local Lattice Distortions, Charge and Spin Ordering [PDF]
, 2000 Keeping in mind the experimental results that indicate local lattice distortions, charge and spin orderings, we have developed a phenomenological approach which allows us to describe the electronic phase diagram of cuprates and related systems in terms ...
