Terahertz-Driven Phonon Upconversion in SrTiO3
Michael Kozina, Michael Fechner, Premysl Marsik +8
Direct manipulation of the atomic lattice using intense long-wavelength laser pulses has become a viable approach to create new states of matter in complex materials. Conventionall…
Effect of interfacial Cr on magnetoelectricity of Fe2/CrO2/BaTiO3(001)
Martin Hölzer, Michael Fechner, Sergey Ostanin +1
On the basis of first-principles calculations we study the effect of interfacial Cr on the magnetoelectric properties of a composite multiferroic Fe_L/BaTiO_3(001), with the Fe thi…
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…
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…
Optically-induced Umklapp shift currents in striped cuprates
Pavel E. Dolgirev, Marios H. Michael, Jonathan B. Curtis +6
Motivated by recent experiments that observed low-frequency second-order optical responses in doped striped superconductors, here we investigate the nonlinear electrodynamics of sy…
The 2025 Roadmap to Ultrafast Dynamics: Frontiers of Theoretical and Computational Modelling
Fabio Caruso, Michael A. Sentef, Claudio Attaccalite +27
The exploration of ultrafast phenomena is a frontier of condensed matter research, where the interplay of theory, computation, and experiment is unveiling new opportunities for und…
