Daniel Harlow
Daniel L. Harlow (* in Cincinnati ) is an American theoretical physicist who studies quantum gravity .
Life
Harlow grew up in Boston and Chicago and graduated from Columbia University with a bachelor's degree in physics and mathematics in 2006. He received his PhD from Stanford University in 2012 , was a post-doctoral student at Princeton University and Harvard University, and has been since 2017 Assistant Professor at the Massachusetts Institute of Technology (MIT).
He deals with quantum gravity in the context of the AdS-CFT correspondence and, together with others, found a connection to quantum information theory via special error-correcting quantum codes with a tensor network structure. These provide a toy model for the quantum entanglement in the AdS-CFT correspondence (Ryu-Takayanagi formula by Shinsei Ryū , Tadashi Takayanagi ).
In addition, he deals in general with the mathematical basis of quantum field theories (structure of conformal quantum field theories and phases of gauge field theories). With Hiroshi Ooguri in 2018 he proved that assuming the AdS / CFT correspondence ( holographic principle ) there are no (exact) global symmetries in quantum gravity. In addition, they derived consequences for internal gauge symmetries that occur in the low-energy range of quantum gravity theory. These must have compact calibration groups and physical (dynamic) states occur in all irreducible representations of the calibration group.
For 2019 he received the New Horizons in Physics Prize for fundamental insights into quantum information, quantum field theory and gravitation (laudation).
He is a member of the It from Qubit Collaboration of the Simons Foundation (led by Patrick Hayden). With Hayden he discovered a connection between information-theoretical complexity theory and black hole physics. They argued that the thought experiments that led to the firewall concept in black hole theory ( Joseph Polchinski and others) are impossible due to the complexity of the calculations required.
As a hobby he plays the piano and hikes.
