• In the PhD projects, Selim contributed to the development of efficient
computational methods using quantum dynamics to simulate molecular collisions
in space in protoplanetary disks.
• Such simulations will provide the collision-induced rotational-vibrational transition
rates needed by the molecular astronomers to interpret the spectra of probe
molecules in protoplanetary disks.
• A contribution to a theoretical modelling of using quantum control for chemical
reactions.
• Such theoretical study contributed to paving the way for designing the parameters
of femto/atto-second laser pulses that can control the chemical reactions.
• Such engineered pulse will select the favorable product channel resulting in
reducing the chemical & material waste

Quantum molecular simulations are computationally challenging >
• Quantum molecular simulations are important to
simulate quantum molecular sensors, chemical reactions, controlled molecular
processes, molecular collisions, molecular interactions, and molecular design.
• Quantum molecular simulations are computationally challenging.
• Example: the time-independent solution of Schrödinger's equation,
called coupled-channels (CC) method.

Computation time scales cubically with the number of
equations being solved >
• Solving the time-independent Schrödinger equation scales
cubically with the number of equations being solved.
• Such theoretical study contributed to paving the way for designing the parameters
of femto/atto-second laser pulses that can control the chemical reactions.
• An efficient quantum simulation engine is needed to
overcome this computational complexity challenge.
