The female scientist of Ton Duc Thang University was awarded the Young Research Award from Association of Theoretical Physics

The Young Research Award is an annual award from Association of Theoretical Physics to present young researchers for excellent publications in the field of Theoretical Physics and other related fields. The Young Research Award 2020 was presented in the 45th Vietnam Conference on Theoretical Physics (VCTP-45) organized by Association of Theoretical Physics and Institute of Physics (Vietnam Academy of Science and Technology) in conjunction with other sponsors from 12 to 14 of this October in Vinh Phuc Province. This year, Dr. Le Thi Cam Tu (Full-time Researcher belongs to Advanced Institute of Materials Science, Ton Duc Thang University) was honored to achieve the Young Researcher Award 2020 from this Conference.

The Science Award and two publications of Dr. Le Thi Cam Tu which achieve the Young Researcher Award 2020

Dr. Le Thi Cam Tu started working at Ton Duc Thang University from October 2018 and successfully defended her PhD thesis in Physics in 2019 at Vietnam National University Ho Chi Minh City - University Of Science (VNUHCM-US). Until now, Dr. Le Thi Cam Tu is the author of 8 publications in ISI journals, including 2 publications in Physical Review A - the leading journal on atomic, molecular and optical physics of the American Physical Society.

Physical Review A (ISSN: 2469-9926, of Amer Physical Soc Publisher) is an ISI journal. The impact factor (IF) in year 2019 is 2.777 according to Journal Citation Reports (Clarivate, USA), and the H-index is 249 according to Scimago (SJR, Spain), with the narrow category of Atomic and Molecular Physics, and Optics.

The two articles were awarded to the Young Researcher Award in 2020 for Dr. Le Thi Cam Tu, that are named as below:

1. The first article: “Effect of the dynamic core-electron polarization of CO molecules on high-order harmonic generation”

2. The second article: “Influence of dynamic core-electron polarization on the structural minimum in high-order harmonics of CO2 molecules”

These two articles are the result of a long-term and extreme elaborate research, due to high requirements of the Physical Review A which accepts only pioneering research papers.

The abstracts for these two articles

The first article: theoretically investigates the influence of dynamic core-electron polarization (DCEP) of CO molecules on high-order harmonic generation (HHG) by solving the time-dependent Schrödinger equation (TDSE). Including DCEP, the variation of the ionization rate in this interval highly correlates to that of the HHG intensity. To better demonstrate this manifestation, the article also shows the alternation DCEP makes on the effective potential that corresponds to the observed change in the ionization rate and consequently the HHG intensity. With the role of DCEP now better understood for the entire range of the orientation angle, this method can be handled more conveniently for calculating the HHG of other targets.

The second article: The laser-induced dynamic core-electron polarization (DCEP) was known critical in the ionization of polar molecules such as CO, it affects the harmonic intensity through the ionization at a specific instant. Consequently, this shifts and sharpens the minima in the HHG spectra, which arise from the two-center interference. To support this point, we provide reliable numerical simulation by solving the time-dependent Schrödinger equation of the coupled CO2 molecule-laser field within the single active electron framework.

With the above achievements, Dr. Le Thi Cam Tu was invited by the VCTP-45 to present a report with the title: "Effect of dynamic core-electron polarization on harmonic process of linear molecules". This is a successful year in scientific research of Ton Duc Thang University (TDTU). TDTU is honored to have 03 inviting reports out of 09 invited reports at the Conference.
