Invitation to the Joint ICTP-SISSA Colloquium by Prof. Subir Sachdev, Harvard University, USA, on "Quantum Entanglement at all Distances" on Tuesday 14 June at 16:00 hrs CET

[ICTP Director]

Dear All,

You are most cordially invited to the Joint ICTP-SISSA Colloquium by 
Prof. Subir Sachdev, Harvard University, USA, on "Quantum Entanglement 
at all Distances"

The Colloquium will take place in the Budinich Lecture Hall on Tuesday 
14 June at 16:00 hrs CET.

*Biosketch: *Subir Sachdev is Herchel Smith Professor of Physics at 
Harvard University. He also holds a visiting position as the James Clerk 
Maxwell Chair in Theoretical Physics at the Perimeter Institute. He is a 
member of the National Academy of Sciences, fellow of the American 
Physical Society and has been awarded several honors, among them the 
Lorentz Chair, Instituut-Lorentz, Leiden University in 2012, and the 
Salam Distinguished Lecturer at the International Center for Theoretical 
Physics, Trieste in 2014. He is a former Member of ICTP's Scientific 
Council.

Subir Sachdev  is a condensed matter physicist well known for his 
research on quantum phase transitions and its application to a variety 
of quantum materials, such as the high temperature superconductors. His 
research seeks to illuminate the boundary between the everyday world we 
live in—in which many but not all phenomena can be explained through 
classical physics—and the subatomic world of quantum physics. These two 
worlds come together at a "quantum phase transition”, where there is a 
change in the macroscopic character of the quantum state describing a 
many-particle system, and manifestations of quantum entanglement appear 
naturally at long distances.

*Abstract:* Entanglement is the strangest feature of quantum theory, 
often dubbed ''spooky action at a distance’’. Quantum entanglement can 
occur on a macroscopic scale with trillions of electrons, leading to 
novel superconductors which can conduct electricity without resistance 
even at relatively high temperatures. These superconductors also display 
a “strange metal” regime in which individual electrons lose their 
identity. Related entanglement structures arise across the horizon of a 
black hole, and give rise to Hawking’s quantum paradox. I will introduce 
and describe these long-standing problems in two very different fields 
of physics, and review progress in resolving them using insights from 
the Sachdev-Ye-Kitaev model.

The talk will be followed by a question/answer session and light 
refreshments will be served on the Leonardo Building Terrace shortly after.

Looking forward to your participation.
