Dirac Semimetal Phase in Rhombohedral CuSe
Thomas Steele, Becker Sharif, David Lederman +2
Having been extensively studied during last decades in the fields of thermoelectics and ionic conductors, the phase of CuSe with antfluoride crystal structure has recentl…
Measurements of electronic band structure in CeCoGe by angle-resolved photoemission spectroscopy
Robert Prater, Mingkun Chen, Matthew Staab +7
We report a comprehensive study of the electronic structure of CeCoGe throughout the entire Brillouin zone in the non-magnetic regime using angle-resolved photoemission spectro…
Exploring the apparent violation of the Mott relation in a noncentrosymmetric kagome ferromagnet
Benjamin Kostroun, Tomoya Asaba, Sean M. Thomas +4
In magnetic topological materials, time-reversal symmetry breaking gives rise to topological point and line nodes with distinctive signatures in the anomalous Hall and anomalous Ne…
Mesoscale variations of chemical and electronic landscape on the surface of Weyl semimetal CoSnS visualized by ARPES and XPS
Sudheer Anand Sreedhar, Matthew Staab, Mingkun Chen +14
The multiple crystalline terminations in magnetic Weyl semimetal CoSnS display distinct topological and trivial surface states, which have successfully been distinguish…
Calculations of Spin Fluctuation Spectral Functions in High-Temperature Superconducting Cuprates
Griffin Heier, Sergey Y. Savrasov
Spin fluctuations have been proposed as a key mechanism for mediating superconductivity, particularly in high-temperature superconducting cuprates, where conventional electron-phon…
Calculated Unconventional Superconductivity via Charge Fluctuations in Kagome Metal CsV3Sb5
Yuan Tian, Sergey Y. Savrasov
Electrons on Kagome lattice exhibit a wealth of features including Dirac points, van Hove singularities and flatbands. When the Fermi level is placed at the van Hove saddle point,…
Electronic structure of Pu and Am metals by self consistent relativistic GW
A. Kutepov, K. Haule, S. Y. Savrasov +1
We present the results of calculations for Pu and Am performed using an implementation of self-consistent relativistic GW method. The key feature of our scheme is to evaluate polar…
Self consistent GW determination of the interaction strength: application to the iron arsenide superconductors
A. Kutepov, K. Haule, S. Y. Savrasov +1
We introduce a first principles approach to determine the strength of the electronic correlations based on the fully self consistent GW approximation. The approach provides a seaml…
Relative importance of crystal field versus bandwidth to the high pressure spin transition in transition metal monoxides
Luke Shulenburger, Sergey Y. Savrasov, R E Cohen
The crystal field splitting and d bandwidth of the 3d transition metal monoxides MnO, FeO, CoO and NiO are analyzed as a function of pressure within density functional theory. In a…
Local Self-Energy Approach For Electronic Structure Calculations
N. E. Zein, S. Y. Savrasov, G. Kotliar
Using a novel self-consistent implementation of Hedin's GW perturbation theory we calculate space and energy dependent self-energy for a number of materials. We find it to be local…
