Dynamical Multiferroicity
Dominik Maximilian Juraschek, Michael Fechner, Alexander V. Balatsky +1
An appealing mechanism for inducing multiferroicity in materials is the generation of electric polarization by a spatially varying magnetization that is coupled to the lattice thro…
Effects of intense optical phonon pumping on the structure and electronic properties of yttrium barium copper oxide
Michael Fechner, Nicola A. Spaldin
We investigate the structural modulations induced by optical excitation of a polar phonon mode in YBaCuO, using first-principles calculations based on density functiona…
Ultrafast Structure Switching through Nonlinear Phononics
Dominik Maximilian Juraschek, Michael Fechner, Nicola Ann Spaldin
We describe an ultrafast coherent control of the transient structural distortion arising from nonlinear phononics in ErFeO. Using density functional theory, we calculate the st…
Fermi surface evolution of Na-doped PbTe studied through density functional theory calculations and Shubnikov-de Haas measurements
P. Giraldo-Gallo, B. Sangiorgio, P. Walmsley +5
We present a combined experimental and theoretical study of the evolution of the low-temperature Fermi surface of lead telluride, PbTe, when holes are introduced through sodium sub…
First-principles calculation of the bulk magnetoelectric monopolization: Berry phase and Wannier function approaches
Florian Thöle, Michael Fechner, Nicola A. Spaldin
We present a formalism to calculate the macroscopic magnetoelectric monopolization from first principles within the density functional theory framework. An expression for the monop…
