Theory of Laser-Controlled Competing Superconducting and Charge Orders
Michael A. Sentef, Akiyuki Tokuno, Antoine Georges +1
We investigate the nonequilibrium dynamics of competing coexisting superconducting (SC) and charge-density wave (CDW) orders in an attractive Hubbard model. A time-periodic laser f…
Ultrafast evolution and transient phases of the prototype out-of-equilibrium Mott-Hubbard material V2O3
G. Lantz, B Mansart, D. Grieger +17
The study of photoexcited strongly correlated materials is attracting growing interest since their rich phase diagram often translates into an equally rich out-of-equilibrium behav…
Self-Optimized Superconductivity Attainable by Interlayer Phase Separation at Cuprate Interfaces
Takahiro Misawa, Yusuke Nomura, Silke Biermann +1
Stabilizing superconductivity at high temperatures and elucidating its mechanism have long been major challenges of materials research in condensed matter physics. Meanwhile, recen…
Photoemission Spectra from Reduced Density Matrices: the Band Gap in Strongly Correlated Systems
Stefano Di Sabatino, J. A. Berger, Lucia Reining +1
We present a method for the calculation of photoemission spectra in terms of reduced density matrices. We start from the spectral representation of the one-body Green's function G,…
Magnetic Collapse and the Behavior of Transition Metal Oxides at High Pressure
I. Leonov, L. Pourovskii, A. Georges +1
We report a detail theoretical study of the electronic structure and phase stability of transition metal oxides MnO, FeO, CoO, and NiO in their paramagnetic cubic B1 structure by e…
