Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

The roles of energy, momentum and orbital angular momentum conservation in high-
harmonic generation were studied in the past. Here, we explore the role of spin angular …

We present a method for producing a single circularly polarized attosecond pulse by an
intense few cycle elliptically polarized laser pulse combined with a terahertz field from …

Nonadiabatic transitions are one of the most important quantum mechanical phenomena in
chemical reaction dynamics. This is because the most interesting chemical and even …

A number of singly (180°) twisted, largely single-stranded and thus conformationally rather
fragile, Möbius molecules have been synthesized within the last 15 years, which are …

By placing Mg-porphyrin molecules in a chiral optical cavity, time reversal symmetry is
broken, and polariton ring currents can be generated with linearly polarized light, resulting in …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

Ionization rates of molecules have been modeled with time-dependent configuration
interaction simulations using atom centered basis sets and a complex absorbing potential …

Atoms are usually thought of as achiral objects. However, one can construct superpositions
of atomic states that are chiral. Here, we show how to excite such superpositions with …
