Konstantin K. Likharev received the Candidate (Ph.D.) degree in Physics from Moscow State University, Russia in 1969, and the habilitation degree of Doctor of Sciences from the Higher Attestation Committee of the U.S.S.R. in 1979. From 1969 to 1988 Dr. Likharev was a Staff Scientist at Moscow State University and from 1989 to 1991, the Head of the Laboratory for Cryoelectronics of that university. In 1991 he assumed a Professorship at Stony Brook University (Distinguished Professor 2002-2017, John Toll Professor 2017-2020, Distinguished Professor Emeritus since September 2020). During his research career, Dr. Likharev worked in the fields of nonlinear classical and dissipative quantum dynamics, and solid-state physics and electronics, notably including superconductor electronics and nanoelectronics. His most recent research interests included nanoelectronic implementation of high-performance neuromorphic networks. Dr. Likharev is an author of more than 350 publications, including 80+ review papers and book chapters, 2 monographs, 8 textbooks, and several patents. Dr. Likharev is a Fellow of the APS and the IEEE.
You are listed as the author of Libretext Essential Graduate Physics – Classical Electrodynamics.
I have a very minor suggestion. In 10.1: Liénard-Wiechert Potentials
Figure 10.3, right after equation 10.22),
I suggest that the diagram be squeezed in the x dimension. As it is, to someone who is just learning, it might seem that the angle has to be pi/4, and also the distance n_ret and u_(t-t_ret) are different but not obviously different.
The diagram is correct as it is, but its meaning might be more obvious with this suggestion.
Thank you very much for your suggestion! I agree with it and will change the figure accordingly. The change should appear later today on the two basic online sites of my course series (for their links, see the ESSENTIAL GRADUATE PHYSICS page on this site) but I am not sure how long it would take LibreTexts to adopt it. Generally, I would recommend using the basic sites directly, because I still update/edit these versions of my series often but do not have direct control over their adaptations.
Hi Prof. Likhareve,
Nothing to really add, but just wanted to thank you for creating this great material and making it generally available. I’m an old failed physicist (PhD Berkeley ’95) who switched to engineering for a career shortly after getting my degree. Instead of crossword puzzles or sudoku to stay sharp, I enjoy reviewing physics and especially solving problems. Your material has provide me with many enjoyable hours!
