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…

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,…

Stable topological insulators achieved using high energy electron beams

Lukas Zhao, Marcin Konczykowski, Haiming Deng +9

Topological insulators are transformative quantum solids with immune-to-disorder metallic surface states having Dirac band structure. Ubiquitous charged bulk defects, however, pull…

Energy Gap Evolution Across the Superconductivity Dome in Single Crystals of (BaK)FeAs

Kyuil Cho, M. Konczykowski, S. Teknowijoyo +8

The mechanism of unconventional superconductivity in iron-based superconductors (IBSs) is one of the most intriguing questions in current materials research. Among non-oxide IBSs,…

The concept of entropic rectifier facing experiments

D. Lairez, M. -C. Clochard, J. -E. Wegrowe

The transport of molecules in confined media is subject to entropic barriers. So theoretically, asymmetry of the confinement length may lead to molecular ratchets with entropy as t…

Derivation of the three-layer model for surface second-harmonic generation

Sean M. Anderson, Bernardo S. Mendoza

We develop explicit expressions for the surface second-harmonic radiation yield using the three layer model. We derive expressions that can be applied to systems without and symmet…
