DESCRIPTION:Full counting statistics out of equilibrium: melting of antifer
 romagnetic order\nMario Collura (Oxford University\, UK)\nOne of the basic
  principles of quantum mechanics is the statistical nature of measurements
  of observables. The result of measurements is indeed described by a pro
 bability distribution\, and measuring the same observable  in identical 
 systems will give different outcomes in accordance with this distribution.
   The full probability distribution carries very detailed information a
 bout the system and\, on top of expectation value\, encodes all fluctuatio
 ns of the system.  I will focus on the non-equilibrium dynamics of a full
 y polarised antiferromagnetic state under the unitary evolution induced by
  the XXZ Hamiltonian. It turns out that\, depending on the value of the in
 teractions\, the full probability distribution of the subsystem staggered 
 magnetisation may retain informations about the original antiferromagnetic
  order\, thus acquiring a shape much different from a simple Gaussian dist
 ribution.\n
