16. Energy flow correlations in CFT

Gregory Korchemsky (Institut de Physique Theorique, Saclay)

Plenary Talk

We present a new approach to computing energy flow correlations in a generic CFT. These infrared finite observables are familiar from collider physics studies and describe the angular distribution of energy in outgoing radiation created from the vacuum by some source. The energy correlations can be expressed in terms of Wightman correlation functions in a certain limit. We explain how to...

34. Universal dynamics of a soliton after a quantum quench

Talk

We propose a new type of experimentally feasible quantum quench protocol. A quantum system is prepared in a coherent, localized excited state of a Hamiltonian, whose interaction strength is characterized by a control parameter. At some point during the evolution of this solitonic excitation, the parameter is suddenly changed. We study the dynamics of solitons after this global quench in a...

10. Large-N asymptotic expansion of multiple integrals related to the quantum separation of variables method

Dr. Karol Kozlowski (CNRS)

15/09/14, 16:30

Talk

The scalar products and certain correlation functions of models solvable by the quantum separation of variables can be expressed in terms of $N$-fold multiple integrals which can be thought of as the partition function of a one dimensional gas of particles trapped in an external potential $V$ and interacting through repulsive two-body interactions of the type $\ln \big[ \sinh[\pi...
