Anderson impurity in a semiconductor [PDF]

open access: yesPhysical Review B, 1996
We study an Anderson impurity in a semiconducting host using the density matrix renormalization group technique. We use the $U=0$ one--dimensional Anderson Hamiltonian at half filling as the semiconducting host since it has a hybridization gap. By varying the hybridization of the host, we can control the size of the semiconducting gap.

Effect of the bi-chromatic ac magnetic field on the quantum spin chain with an impurity

open access: yesCondensed Matter Physics, 2021
The linear response of the quantum spin chain with the impurity to the bi-chromatic ac magnetic field has been calculated. The linearly polarized component of the ac field produces additional resonance absorption with respect to the one caused by the ...

Quarantäne, Einsamkeit und Psalmen

open access: yesHTS Teologiese Studies/Theological Studies, 2020
Quarantine, loneliness and psalms: In times of a pandemic, quarantine and physical distance are acts of charity. Leviticus 13–14 show that even in biblical times such measures served to protect the community.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
