Researchers at The University of Tokyo demonstrate enhanced radiative heat transfer across a gap between two micro-sized silicon plates by coating them with a layer of silicon dioxide, which may significantly improve heat management of computers.

Osaka Metropolitan University scientists detected, for the first time, collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies.

Dr. Nishikawa at Osaka Metropolitan University focused on the Kondo effect on minimal ferrimagnetism and attempted to elucidate it theoretically. As a result, they found that the Kondo effect occurred via multiple "quantum entangled states" depending on temperature and other factors. They also found that the Kondo effect suppressed electrical conductivity through minimal ferrimagnetism, when usually it is amplified in many other cases.

Giants in history

Mohammad Abdus Salam (29 January 1926 – 21 November 1996) was a theoretical physicist and the first Pakistani to receive a Nobel Prize in science.
Bibha Chowdhuri (1913 – 2 June 1991) was an Indian physicist who researched on particle physics and cosmic rays. In 1936, she was the only female to complete a M.Sc. degree at the University of Calcutta.
