Colloquium 14 June: Subir Sachdev


ICTP is pleased to announce that distinguished physicist Subir Sachdev will deliver a lecture on "Quantum Entanglement at all Distances". The talk is part of a series of joint colloquia organised together with the Trieste-based International School for Advanced Studies (SISSA) and will take place Tuesday 14 June in ICTP's Budinich Lecture Hall starting at 16:00 CET. All are welcome to attend.

The Colloquium will also be live-streamed on ICTP's YouTube channel, and can be followed online by registering at the following Zoom link:

Sachdev, a condensed matter physicist well known for his research on quantum phase transitions and its application to a variety of quantum materials, is the Herchel Smith Professor of Physics at Harvard University. The abstract of his talk is as follows:

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. Sachdev 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.

About Subir Sachdev: Professor Sachdev's 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. He is a member of the US National Academy of Sciences, fellow of the American Physical Society and has been awarded several honours, among them ICTP's Dirac Medal, awarded in 2018 and shared with Dam Thanh Son and Xiao-Gang Wen. He is a former Member of ICTP's Scientific Council.
