Hi all,
this is a reminder of Luigi Amico's talk today at 4pm in the Time
Room.

Title: Entanglement transition in quantum magnets
Speaker: Luigi Amico (University of Catania)
Abstract:
Entanglement is a defining feature of quantum mechanics that in
recent years has led to the development of the new discipline of
quantum information theory. Its application to spin systems predicts
a new type of zero temperature transition in an applied magnetic
field at which the nature of the entanglement qualitatively changes
without any anomaly in the ground state energy of the system. I
will discuss the correlations near such an entanglement transition.
I will report on the first attempt to observe the phenomenon with a
neutron scattering experiment in a one dimensional quantum magnet.
