Physics Seminar: Professor Vyacheslavs Kasheyevs

Presenter

Professor Vyacheslavs Kasheyevs
University of Latvia

Professor Vyacheslavs (Slava) Kashcheyevs is Nanoelectronics theory group leader at the Department of Physics of University of Latvia in Riga, Latvia.

He holds PhD degree from Tel Aviv University (2007). In 2013, prof. Kashcheyevs has been named by World Economic Forum as one of the forty “Young scientists of 2013” for his work on quantum-dots-based electrical current standard, and elected as associate member by Latvian Academy of Sciences.

His current research is focused on single-electron quantum optics and more general theoretical aspects of quantum advantage in physical systems.

 

Solitary electrons in semiconductor circuits

Individual electrons confined to quantum dots and guided along nanowire edges in semiconductors circuits form an exciting quantum technology platform being actively developed for applications in metrology, quantum sensing and quantum computing. Precision of electron counting now rivals even the most accurate electrical measurements putting within the reach direct realisation of the quantum Ampere in the redefined SI. Availability of on-demand electron sources has enabled chip-level collider experiments implementing few-particle quantum optics with interacting fermions.

In the talk I will discuss the main concepts and recent advances in the field of single-electronics, drawing upon experience of the Nanoelectronics theory group at University of Latvia in collaboration with experimental laboratories at European National metrology in Germany (PTB) and the UK (NPL), as well as recent collaboration with University of New South Wales and University of Adelaide.
