Optical manipulation of magnetization with femtosecond laser pulses has opened a new
paradigm shift in magnetization and spin dynamics. Since the very first demonstration of …

High-intensity THz lasers allow for the coherent excitation of individual phonon modes. The
ultrafast control of emergent magnetism by means of phonons opens up new tuning …

Using an ultrafast laser pulse to manipulate the spin degree of freedom has broad
technological appeal. It allows one to control the spin dynamics on a femtosecond time …

We prove both analytically and numerically that the total angular momentum of a molecular
system undergoing adiabatic Born-Oppenheimer dynamics is conserved only when …

In several settings of physics and chemistry one has to deal with molecules interacting with
some kind of an external environment, be it a gas, a solution, or a crystal surface …

Studying chemical reactions at very low temperatures is of importance for the understanding
of fundamental physical and chemical processes. At very low energies, collisions are …

An electronic theory of the laser-induced ultrafast magnetization dynamics in transition-metal
alloys is presented. A many-body model Hamiltonian is considered that incorporates the …

The notion that phonons can carry pseudo‐angular momentum has many major
consequences, including topologically protected phonon chirality, Berry curvature of phonon …

When a magnetic film is excited by a femtosecond laser pulse, either with THz or with optical
frequencies, then there is at least a partial demagnetization within a few hundred …

Recently it was shown that an impurity exchanging orbital angular momentum with a
surrounding bath can be described in terms of the angulon quasiparticle [Phys. Rev. Lett …
