Thomas Baumert

6/24/25, 9:10 AM

Invited talk

Exploiting an electric dipole effect in ionization [1], photoelectron circular dichroism (PECD) is a highly sensitive enantioselective spectroscopy for studying chiral molecules in the gas phase using either single-photon ionization [2] or multiphoton ionization [3]. In the latter case, resonance-enhanced multiphoton ionization (REMPI) gives access to neutral electronic excited states. The...

228. Exciting and probing attosecond multielectron dynamics in chiral molecules at FERMI

Davide Facciala' (CNR-IFN)

6/24/25, 9:40 AM

Contributed talk

Little is known about attosecond multielectron dynamics in photo-excited chiral molecules and their coupling to vibronic dynamics triggered by photoexcitation. Such photodynamics is of great importance for understanding photo-processes triggered in chiral molecules by electromagnetic radiation in outer space; this has important implications in bio-astrophysics and in the search for the origin...

38. Ultra-fast nonlinear optical response of chiral molecules with a focus on conformer sensitivity

Elena Aethra Christou (Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy)

6/24/25, 10:00 AM

Contributed talk

Chirality is a fundamental geometric property, present from molecular to macroscopic scales. Traditional chiroptical methods rely on weak magnetic interactions, limiting their efficiency. We aim to develop chiral recognition methods based solely on electric-dipole interactions, offering enhanced enantiosensitivity [1].

We investigate the carrier-envelope phase (CEP) dependence of...

133. Light emission with a twist: Ultrafast evolution of chiral excited states determines the circularly-polarized luminescence of a chiral OLED complex

Ms Livia Müller (Department of Chemistry, University of Basel, Switzerland)

6/24/25, 10:20 AM

Contributed talk

Circularly-polarized luminescence (CPL) has promising applications in the fields of optical data storage, biosensing and for the creation of more efficient OLED displays [1]. In this respect, chiral lanthanide complexes are particularly attractive CPL emitters due to their intense and long-lived emission lines, and their exceptional degree of circular polarization. However, despite the...
