Congratulates to Eran Ben Arosh for winning the PBC scholarship for outstanding doctoral students in quantum science and technology

Congratulations to Eran Ben Arosh for winning the Planning and Budgeting Committee of the Council for Higher Education  (PBC)  scholarship for outstanding doctoral students in quantum science and technology. The scholarship is given for 3 academic years.

In Eran's research, a powerful laser emitting ultra-short pulses of light is used to "film" electrons in chemical bonds (aka" Orbitals ",  the building blocks of chemistry) with attosecond time resolution (an attosecond is one billionth of a billionth of a second).

These short light pulses can ionize electrons through a quantum process called tunneling and even induce the emission of coherent XUV radiation via a high harmonic generation mechanism (a phenomenon in extreme nonlinear optics), which can further ionize additional electrons.

In the final stage, the electrons are collected by a state-of-the-art apparatus called COLTRIMS, which can measure the three-dimensional momentum vector of a single electron following ionization.

Since these momentum distributions contain rich information about electronic dynamics, they are analyzed using image processing tools and phase retrieval algorithms to achieve a spatiotemporal tomographic reconstruction of Orbitals.

Acquiring this fundamental knowledge will lead to a deeper understanding of chemical reactions and lay the foundation for developing methods to control them.
