Professor | King Saud University | Saudi Arabia

Dr. Vassilis E. Lembessis is a leading physicist internationally recognized for his influential contributions to quantum optics, laser cooling and trapping, twisted light beams, and plasmonics. His research primarily investigates the interaction between atoms and structured light fields, exploring how the angular momentum, phase, and topology of light influence atomic dynamics and quantum behavior. With an extensive citation record exceeding 1,700 citations, an h-index of 18, and an i10-index of 34, his scientific work has profoundly shaped the theoretical and experimental frontiers of modern optical physics.A central theme of Dr. Lembessis’s research is the manipulation of ultracold atoms and quantum gases using complex optical fields. His highly cited papers, such as “Optical Ferris Wheel for Ultracold Atoms” and “Atoms in Complex Twisted Light,” have introduced groundbreaking models for controlling atomic motion through optical vortices and Laguerre–Gaussian beams. These studies have provided fundamental insights into optical angular momentum transfer, light-induced forces, and coherent control in atomic systems.Dr. Lembessis has also advanced the understanding of surface plasmon optical vortices, spin–orbit coupling in light beams, and light-induced torque in Bose–Einstein condensates, bridging the gap between classical electromagnetism and quantum phenomena. His research reveals how tailored light structures can generate new forms of atomic trapping, guiding, and rotation—paving the way for emerging technologies in quantum manipulation, photonic nanodevices, and precision measurement.His collaborative work with prominent researchers across global institutions continues to deepen the theoretical framework of light–matter interactions, addressing phenomena such as enhanced quadrupole effects, atomic vortex generation, and plasmonic field singularities. These investigations have implications not only for fundamental quantum theory but also for practical advancements in quantum computing, optical communications, and nanophotonics.Through his innovative and interdisciplinary approach, Dr. Vassilis E. Lembessis has become a prominent figure in contemporary physics, consistently expanding the boundaries of light–matter science and inspiring future exploration into quantum technologies and structured photonic systems that define the next generation of optical and quantum research.

Senior Professor | Belarusian State University | Belarus

Prof. Dr. Albert Vitoldovich Minkevich, born in 1941 in Minsk, Belarus, is a distinguished theoretical physicist whose lifelong academic journey has been dedicated to advancing the frontiers of gravitation and cosmology. He completed his higher education at the Belarusian State University, graduating with honors in Theoretical Physics in 1963, and went on to earn his Ph.D. in 1970 with a thesis on the interaction of gravitational and other physical fields. He further achieved the prestigious Doctor of Physical and Mathematical Sciences degree in 1986 for his groundbreaking work on the gauge approach in gravitation theory. Over the course of his academic career, he advanced from Assistant Lecturer to Full Professor at the Faculty of Physics, Belarusian State University, and also served internationally as a professor at the University of Boumerdès in Algeria (1988–1992) and at the University of Warmia and Mazury in Poland (2000–2015). His research interests lie at the intersection of gravitation, cosmology, and astrophysics, with a focus on applying variational methods and gauge theories to solve fundamental problems such as the cosmological singularity, dark matter, dark energy, and the accelerated expansion of the universe. His pioneering contributions include the development of isotropic cosmological models in Riemann-Cartan space-time, which eliminate singularities and propose alternatives to dark energy explanations, as well as insights into gravitational repulsion and torsion effects in astrophysical systems. Professor Minkevich’s research skills span advanced mathematical physics, including group theory, tensor analysis, differential geometry, and differential equations, which he has effectively applied to cosmological modeling and gravitational theory. He has authored more than 200 peer-reviewed publications, delivered invited talks at leading international conferences across Europe, Asia, and the Americas, and supervised numerous doctoral theses that extended his legacy in theoretical physics. Throughout his illustrious career, he has served as an editorial board member and reviewer for leading journals, played active roles in program committees of prestigious global conferences such as the Marcel Grossmann Meetings, and maintained long-standing collaborations with research institutions across Poland, Germany, France, the USA, and Vietnam. His honors include election to the European Academy of Sciences (Belgium) in 2002, in recognition of his outstanding contributions to theoretical physics and cosmology. Professor Minkevich’s lifelong commitment to advancing knowledge, mentoring future scientists, and contributing to international collaborations underscores his standing as a globally respected scholar.
