Dynamically suppressed lattice rotations in SrTiO as a basis for photo-induced ferroelectricity
Huaiyu Hugo Wang, Michael Fechner, Giovanni De Vecchi +22
Photo-induced ferroelectricity in the quantum paraelectric SrTiO involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural…
Search for the magnetic monopole at a magnetoelectric surface
Q. N. Meier, M. Fechner, T. Nozaki +11
We show, by solving Maxwell's equations, that an electric charge on the surface of a slab of a linear magnetoelectric material generates an image magnetic monopole below the surfac…
Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics
Alexander von Hoegen, Roman Mankowsky, Michael Fechner +2
Femtosecond optical pulses at mid-infrared frequencies have opened up the nonlinear control of lattice vibrations in solids. So far, all applications have relied on second order ph…
Linear Magnetoelectric Effect by Orbital Magnetism
Andrea Scaramucci, Eric Bousquet, Michael Fechner +2
We use symmetry analysis and first principles calculations to show that the linear magnetoelectric effect can originate from the response of orbital magnetic moments to the polar d…
Strong influence of the complex bandstructure on the tunneling electroresistance: A combined model and ab-initio study
N. F. Hinsche, M. Fechner, P. Bose +4
The tunneling electroresistance (TER) for ferroelectric tunnel junctions (FTJs) with BaTiO_{3} (BTO) and PbTiO}_{3} (PTO) barriers is calculated by combining the microscopic electr…
Effect of the surface polarization in polar perovskites studied from first principles
M. Fechner, S. Ostanin, I. Mertig
The (001) surfaces of polar perovskites BaTiO and PbTiO have been studied from first principles at T=0 K. For both cases of polarization, the most stable TiO-terminated int…
