Emergence and spectral-weight transfer of electronic states in the Hubbard ladder [PDF]

Phys. Rev. B 100, 235143 (2019), 2019
The number of electronic bands is usually considered invariant regardless of the electron density in a band picture. However, in interacting systems, the spectral-weight distribution generally changes depending on the electron density, and electronic states can even emerge or disappear as the electron density changes.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

FEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

OVERVIEW OF X-RAY FLUORESCENCE SPECTROMETRY [PDF]

Fiabilitate şi Durabilitate, 2021
One of the techniques used in identifying the constituent chemical elements of a material is the X-ray fluorescence method. From the analysis of X-ray fluorescence data the energy and intensity of the characteristic photons emitted by the sample can be

Exact Electron-Pairing Ground States of Tight-Binding Models with Local Attractive Interactions [PDF]

, 2003
We present a class of exactly solvable models of correlated electrons. The models are defined in any dimension $d$ and consist of electron-hopping terms and local attractive interactions between electrons. For each even number of electrons less than or equal to $1/(d+1)$-filling, we find the exact ground state in which all electrons form pairs of a ...

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases

FEBS Letters, EarlyView.
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Robust and adjustable C-shaped electron vortex beams

New Journal of Physics, 2017
Wavefront engineering is an important quantum technology, often applied to the production of states carrying orbital angular momentum (OAM). Here, we demonstrate the design and production of robust C-shaped beam states carrying OAM, in which the usual ...

Photoluminescence of Cis-Polyacetylene Semiconductor Material

Applied Sciences, 2022
Photoluminescence (PL) is one of the key experimental characterizations of optoelectronic materials, including conjugated polymers (CPs). In this study, a simplified model of an undoped cis-polyacetylene (cis-PA) oligomer was selected and used to explain

Electron correlations in narrow energy bands

Proceedings of the Royal Society of London. Series A, Mathematical and physical sciences, 1963
It is pointed out that one of the main effects of correlation phenomena in d- and f-bands is to give rise to behaviour characteristic of the atomic or Heitler-London model.

Energy relaxation in the spin-polarized disordered electron liquid [PDF]

Phys. Rev. Lett. 100, 206804 (2008), 2007
The energy relaxation in the spin-polarized disordered electron systems is studied in the diffusive regime. We derived the quantum kinetic equation in which the kernel of electron-electron collision integral explicitly depends on the electron magnetization.
