Hélène Bouchiat
Hélène Bouchiat (born May 8, 1958 ) is a French physicist.
Bouchiat, the daughter of the physicists Marie-Anne Bouchiat and Claude Bouchiat , studied from 1977 to 1981 at the École normal des jeunes filles and received her doctorate in 1986 at the Laboratory for Solid State Physics of the University of Paris-Süd in Orsay under Philippe Monod ( Transition du verre de spin: comportement critique et bruit magnétique ). As a post-doctoral student, she was at Bell Laboratories . In 1988 she was back at the Laboratory for Solid State Physics in Orsay, where she became Research Director of the CNRS .
She studies quantum transport in mesoscopic systems such as carbon nanotubes and DNA and molecular electronics. For example, she investigated the Josephson effect of carbon nanotubes and graphene . At the Bell Laboratories at the end of the 1980s she found evidence of permanent currents in small (mesoscopic) conductor rings in magnetic fields in the form of a flux quantum (without superconductivity). As it turned out later, this is due to the Aharonov-Bohm effect .
In 2010 she became a member of the Académie des sciences . In 1987 she received the bronze medal and the silver medal of the CNRS in 2007 and the Prix Jaffé in 1998. She is on the scientific council of the CEA .
