Quantifying electronic correlation strength in a complex oxide: A combined DMFT and ARPES study of LaNiO3
(American Physical Society, 2015-12-07)
The electronic correlation strength is a basic quantity that characterizes the physical properties of materials such as transition metal oxides. Determining correlation strengths requires both precise definitions and a ...
New class of planar ferroelectric Mott insulators via first-principles design.
(American Physical Society, 2015-12-11)
The bulk photovoltaic effect requires a low electronic band gap (i.e., ≈1–2 eV) and large electronic polarization, which is not common in known materials. Here we use first-principles calculations to design layered double ...
