Magnetic and nonmagnetic phases in doped AB2 t-J Hubbard chains

Autor: Montenegro-Filho, R. R., Coutinho-Filho, M. D.

Publikováno v: Phys. Rev. B 90, 115123 (2014)

We discuss the rich phase diagram of doped AB2 $t-J$ chains by using data from density matrix renormalization group and exact diagonalization techniques. The $J$ vs $\delta$ (hole doping) phase diagram exhibits regions of itinerant ferrimagnetism, in

Competing phases in the extended U-V-J Hubbard model near the van Hove fillings

Autor: Kampf, A. P., Katanin, A. A.

Publikováno v: Phys. Rev. B 67, 125104 (2003)

The phase diagram of the two-dimensional extended one-band U-V-J Hubbard model is considered within a mean-field approximation and two- and many-patch renormalization group (RG) approaches near the van Hove band fillings. At small t' and J>0 mean-fie

The CCD instrument background of the SMILE SXI

Autor: M. W. J. Hubbard, O. Hetherington, D. J. Hall, T. W. Buggey, S. Parsons, T. Arnold, A. Holland, C. Pagani, S. Sembay

Publikováno v: Earth and Planetary Physics, Vol 8, Iss 1, Pp 15-24 (2024)

The ESA and CAS SMILE mission orbit is highly elliptical and will pass through multiple radiation environments. The Soft X-ray Imager (SXI) instrument aboard has a radiation shutter door designed to close when the surrounding radiation flux is high.

SMILE soft X-ray Imager flight model CCD370 pre-flight device characterisation

Autor: S. Parsons, D. J. Hall, O. Hetherington, T. W. Buggey, T. Arnold, M. W. J. Hubbard, A. Holland

Publikováno v: Earth and Planetary Physics, Vol 8, Iss 1, Pp 25-38 (2024)

Throughout the SMILE mission the satellite will be bombarded by radiation which gradually damages the focal plane devices and degrades their performance. In order to understand the changes of the CCD370s within the soft X-ray Imager, an initial chara

Isoform-specific sequestration of protein kinase A fine-tunes intracellular signaling during heat stress

Autor: Declan R. Creamer, Robert J. Beynon, Simon J. Hubbard, Mark P. Ashe, Chris M. Grant

Publikováno v: Cell Reports, Vol 43, Iss 6, Pp 114360- (2024)

Summary: Protein kinase A (PKA) is a conserved kinase crucial for fundamental biological processes linked to growth, development, and metabolism. The PKA catalytic subunit is expressed as multiple isoforms in diverse eukaryotes; however, their contri
