JINR-UNISA COLLABORATION ON NONLINEAR AND CHAOTIC PHENOMENA OCCURING IN SUPERCONDUCTING ELECTRONIC AND SPINTRONIC JOSEPHSON STRUCTURES

25 Jun 2025, 09:00

30m

conference hall (BLTP)

Oral Wednesday

Speaker

Prof. Yu. M. Shukrinov (BLTP, JINR, Dubna)

Description

An overview of the results obtained in the framework of JINR-UNISA collaboration in
the field of theoretical research on superconducting electronics, spintronics and chaos is
presented [1-7]. The important role played by nonlinear and chaotic phenomena in
different types of Josephson structures will be discussed within the context of our present
studies and future plans.
