Ventsislav K. Valev, (born 31 August 1976 in Silistra, Bulgaria), is a Bulgarian physicist at the University of Bath, where he served as the Head of Department (2022-2025). [1] He works in the fields of nonlinear nanophotonics [2] and chirality, [3] [4] including the Hyper Rayleigh Scattering Optical Activity effect. [5]

Career

Valev holds a PhD degree from Radboud University, obtained under the supervision of Prof. Theo Rasing. [6] Valev joined the University of Bath as a University Research Fellow of the Royal Society and Reader (Associate Professor) in 2014. He serves as the Head of the University's Department of Physics starting from 2022 to today. [1]

Research

Valev’s research has focused on nonlinear and chiral optical effects in nanostructured materials. In 2009, he and his colleagues used second-harmonic generation imaging to study electromagnetic responses in G-shaped gold nanostructures, introducing what they described as electromagnetic chiral hotspots. [7] Later work from Valev and co-authors demonstrated sub-wavelength metal reshaping associated with temperature increases in plasmonic hotspots. [8] Valev’s group has experimentally demonstrated several nonlinear chiral optical effects that were theoretically predicted decades earlier by David L. Andrews. [5] This includes Hyper Rayleigh Scattering Optical Activity, [9] Hyper-Mie Optical Activity, [10] Hyper-Tyndall Optical Activity, [11] and Hyper-Raman Optical Activity. [12]
