Synopsis: We introduce a new phenomenon - enantio-sensitive orientation of chiral molecules via photoionization and uncover the new class of the efficient enantio-sensitive observables in photoionization associated with ultrafast excitation of chiral electronic or vibronic currents.

Chiral molecules are instrumental for molecular class of efficient enantio-sensitive observables recognition in living organisms. Distinguishing emerging in non-linear photoionization. We formulate between two enantiomers, the twins of the same the fundamental principles which allow one to predict chiral , is both vital and challenging. the new enantio-sensitive observables. Crucially, the Photoelectron circular (PECD) is an emergence of these new observables is associated with extremely sensitive probe of molecular , ultrafast excitation of chiral electronic or vibronic which outperforms standard optical methods by many currents prior to and can be viewed as their orders of magnitude [1-9]. We show that the unique signature. To illustrate our concept we emergence of PECD can be linked to the concept of introduce a new phenomenon - enantio-sensitive geometric magnetism, which enables a broad class of orientation of chiral molecules via photoionization, phenomena in condensed matter systems including the opening the way to efficient enantio-separation and anomalous velocity and the Hall effect and molecular imaging on ultrafast time scales. Imaging of related topological phenomena [11]. Following this geometric field and new ultrafast enantio-sensitive link, we uncover geometric magnetic field in observables – messengers of charge -directed photoionization of chiral molecules and we show that photoreactivity is a new frontier in non-linear PECD is only a tip of the iceberg – the iceberg is a new photoionization.
