Potential high-Tc superconducting lanthanum and yttrium hydrides at high pressure
- H. Liu, I. Naumov, R. Hoffmann, N. Ashcroft, R. Hemley
- Materials Science, Medicine
- Proceedings of the National Academy of Sciences
- 19 June 2017
Significance Theoretical predictions and subsequent experimental observations of high-temperature superconductivity in dense hydrogen-rich compounds have reinvigorated the field of superconductivity.… Expand
Hydrogen dominant metallic alloys: high temperature superconductors?
- N. Ashcroft
- Materials Science, Medicine
- Physical review letters
- 6 May 2004
The arguments suggesting that metallic hydrogen, either as a monatomic or paired metal, should be a candidate for high temperature superconductivity are shown to apply with comparable weight to… Expand
Electron-ion pseudopotentials in metals☆
- N. Ashcroft
- Physics
- 3 October 1966
Abstract Pseudopotential form-factors for Al, Pb, Na and K are plotted for a simple model potential which is justified in the text. They are in good agreement with potentials of Heine and Abarenkov.
A little bit of lithium does a lot for hydrogen
- E. Zurek, R. Hoffmann, N. Ashcroft, A. Oganov, A. Lyakhov
- Chemistry, Medicine
- Proceedings of the National Academy of Sciences
- 20 October 2009
From detailed assessments of electronic structure, we find that a combination of significantly quantal elements, six of seven atoms being hydrogen, becomes a stable metal at a pressure approximately… Expand
Atomic and Ionic Radii of Elements 1-96.
- M. Rahm, R. Hoffmann, N. Ashcroft
- Chemistry, Medicine
- Chemistry
- 4 October 2016
Atomic and cationic radii have been calculated for the first 96 elements, together with selected anionic radii. The metric adopted is the average distance from the nucleus where the electron density… Expand
Benzene under high pressure: a story of molecular crystals transforming to saturated networks, with a possible intermediate metallic phase.
- Xiaodong Wen, R. Hoffmann, N. Ashcroft
- Chemistry, Medicine
- Journal of the American Chemical Society
- 20 May 2011
In a theoretical study, benzene is compressed up to 300 GPa. The transformations found between molecular phases generally match the experimental findings in the moderate pressure regime (<20 GPa):… Expand
Structure and bandgap closure in dense hydrogen
- K. Johnson, N. Ashcroft
- Chemistry, Medicine
- Nature
- 10 February 2000
The possibility that steadily compressed hydrogen might undergo a transition from a proton-paired insulator to a monatomic metal was first suggested in 1935 (ref. 1). But experimental realization of… Expand
The unusual and the expected in the Si/C phase diagram.
- G. Gao, N. Ashcroft, R. Hoffmann
- Chemistry, Medicine
- Journal of the American Chemical Society
- 24 July 2013
In the Si/C phase diagram, the only stable phases at P = 1 atm are the numerous polytypes of the simplest 1:1 stoichiometry, SiC. However, many metastable yet likely to be kinetically persistent… Expand
Pairing in dense lithium
- J. Neaton, N. Ashcroft
- Physics
- Nature
- 8 July 1999
The light alkali metals have played an important role in the developing understanding of the electronic structure of simple metals. These systems are commonly viewed in terms of an underlying… Expand
