Marina Huerta

Marina Huerta (born 1968) is an Argentinian theoretical physicist and a physics professor. She is known for her work on quantum entropy in quantum field theory. She has provided a new interpretation of the Bekenstein bound. As of 2020, she has 29 peer-reviewed publications with more than 2000 citations.

In 2014 she won the New Horizons in Physics - Breakthrough Prize for "fundamental ideas about entropy in quantum field theory and quantum gravity".

She researches quantum field theory and quantum information at the Centro Atómico Bariloche and the Argentinian research organization: CONICET. She is a professor at the Instituto Balseiro of the Universidad Nacional de Cuyo in Argentina where her lectures on special relativity have been filmed and are offered free of charge (in Spanish). The Strings School has published her lectures on entanglement entropy (in English).

Biography
Marina Huerta was born in 1968 in Buenos Aires, Argentina. She studied at the Universidad de Buenos Aires (UBA) and then moved to the Instituto Balseiro. She obtained her Ph.D. in physics in the year 2000 after completing a doctoral dissertation on an effective description of the Quantum Hall Effect under the supervision of Guillermo Zemba and Rafael Montemayor. In 2005 and then in 2014, she spent some time at Princeton's Institute for Advanced Study. On the 2014 visit, Huerta researched entanglement entropy which enlightens aspects of quantum field theory inaccessible with any other approach.

She was one of the organizers of the workshop 'Quantum Gravity in the Southern Cone' in 2019.

Contributions to physics
Huerta main contribution in theoretical physics is in geometric entropy in quantum field theory, holography, quantum gravity and quantum information theory. She uses interlacing entropy as an indicator of confinement and phase transitions. It is considered the natural order parameter for systems with topological order. Relative entropy's properties give rise to the Bekenstein dimension, energy levels in field theories and the generalized second law. She has provided a new interpretation of the Bekenstein bound using relative entropy and distinguishability of states.

Interlacing entropy is essential in holography, which relates quantum gravity theories to non-gravitational field theories with one less dimension. Interlacing is necessary to explain the connectivity of space and to describe physics beyond the event horizon.
