Sean Hartnoll
Sean Alexander Hartnoll is a British theoretical physicist.
Hartnoll studied at Cambridge University (DAMTP), where he received his doctorate in theoretical physics under Gary Gibbons (duality and instability in higher dimensional gravity) in 2004 . He was a Cambridge Fellow at Clare College. As a post-doctoral student he was at the Kavli Institute for Theoretical Physics and at Harvard University with Subir Sachdev and Andrew Strominger . In 2009 he was a visiting scholar at the Institute for Advanced Study . He has been an Assistant Professor at Stanford University since 2010 .
Hartnoll is pursuing the program, initiated in particular by Sachdev, of the application of concepts from string theory and the quantum theory of black holes ( AdS / CFT correspondence , holographic principle) in solid-state physics of strongly correlated quantum mechanical many-particle systems, such as high-temperature superconductors (and other non-conventional superconductors) and models Quantum phase transitions. An additional space dimension is added to the system. The process can also be understood as the geometrization of the renormalization group flow between the ultraviolet range (UV), which is well understood in solid-state physics, at higher energies or short distances ( Coulomb interaction of electrons) and the long-range infrared range (IR), which is defined by Wants to better understand consideration in the gravitational dual theory. Conversely, with colleagues in the gravitational sector of the holographic principle, he constructed models that are dual to exotic metals, i.e. those that cannot be described by the Landausche theory of Fermi liquids with its quasiparticle concept. Among them were the models he called electron stars , which correspond to the gravitational sector of the holographic correspondence of an ideal charged and gravitationally interacting fluid of fermions in 3 + 1 space-time dimensions and are described by a Reissner-Nordström solution .
In 2015 he received the New Horizons in Physics Prize for the application of holographic methods in solid state physics. He was a Sloan Fellow and received a Presidential Early Career Award. In 2001 he received the Mayhew Prize of the DAMTP.
