Solving the World's Challenges, Several Indian Americans Elected American Academy of Arts & Sciences Members for 2021 | Global Indian

The American Academy of Arts & Sciences April 22 announced its 2021 group of new members, with several Indian Americans chosen in various categories among the 252 new additions.
The Academy was established in 1780 by the countryâs founders to provide guidance to a young nation that would face challenges and need expertise and excellence to emerge stronger. While the founders did not anticipate a year with a historic pandemic, overdue racial reckoning, and political strife, the purpose of electing new members is more compelling than ever, according to a press release.
The 2021 election provides an opportunity to recognize extraordinary people who help solve the worldâs most urgent challenges, create meaning through art, and contribute to the common good from every field, discipline, and profession, it noted. ....

Twisted trilayer graphene supports existence of exotic superconductivity

1,2
Graphene famously conducts electrons as though they were massless particles like photons, which means that their speed does not depend on their energy. However, just as the speed of light varies in different materials, the speed of electrons in graphene can be controlled. It was predicted to hit zero in bilayer graphene with a ‘magic angle’ twist of 1.1° between the layers, allowing electron–electron interactions to dictate the structure’s properties. In 2018, Pablo Jarillo-Herrero and colleagues at the Massachusetts Institute of Technology confirmed this, showing that feeding electrons into twisted bilayer graphene at cryogenic temperatures could produce a novel superconductor. Subsequently, says Jarillo-Herrero, various groups – including his own – have tested other twisted systems. ‘They have found interesting correlated [electron] materials and correlated behaviour, but none of them was a robust superconductor.’ ....

Trilayer Graphene Could Decode Secrets of High-Temperature Superconductivity

Trilayer Graphene Could Decode Secrets of High-Temperature Superconductivity
The breakthrough
discovered
that when an ultrathin carbon layer, known as graphene, is stacked together and twisted to a magic angle, that novel double-layered structure changes into a superconductor, enabling electricity to flow without energy waste or any kind of resistance.

In what seemed to be a literal twist, Harvard University researchers have now taken that superconducting system to a whole new level by adding a third layer and rotating it, paving the way for continued developments in graphene-based superconductivity. ....
