We review the application of ultrafast optical spectroscopy in the study of correlated electron
materials. The emphasis is on all-optical pump–probe and optical pump–far-infrared probe …

Condensed matter is one of the most active areas of research in physics. Ev ery year new
materials are discovered with properties that are as challenging as or more than those of the …

Strongly correlated electron systems often exhibit very strong interactions between structural
and electronic degrees of freedom that lead to complex and interesting phase diagrams,. For …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

The dynamic tuning of ion concentrations has attracted significant attention for creating
versatile functionalities of materials, which are impossible to reach using classical control …

We assess the performance of the Heyd-Scuseria-Ernzerhof (HSE) screened hybrid density
functional scheme applied to the perovskite family La MO 3 (M= Sc–Cu) and discuss the role …

Using the newly developed VASP2WANNIER90 interface we have constructed maximally
localized Wannier functions (MLWFs) for the eg states of the prototypical Jahn–Teller …

The origin of the cooperative Jahn-Teller distortion and orbital order in LaMnO 3 is central to
the physics of the manganites. The question is complicated by the simultaneous presence of …

The 2-orbital Kondo model with classical Jahn-Teller phonons is studied using Monte Carlo
techniques. The observed phase diagram is rich and includes a novel regime of phase …

We use femtosecond x-ray diffraction to probe directly the structural dynamics of a charge
ordered and orbitally ordered thin film of La 0.42 Ca 0.58 MnO 3 initiated by an ultrafast …
