SUMMARY:Informal quantum seminar: Sara Murciano (LPTMS) - Salle des sémina
 ires du FAST et du LPTMS\, bâtiment Pascal n°530 - 20 Fév 26 14:00
DESCRIPTION:Experimental observation of conformal field theory spectra\nSar
 a Murciano (LPTMS)\n&nbsp\;\n\nConformal field theories (CFTs) feature pro
 minently in high-energy physics\, and condensed matter. For example\, CFTs
  govern emergent universal properties of systems tuned to quantum phase tr
 ansitions\, including their entanglement or correlations. Much of the rich
  structure predicted by CFTs nevertheless remains unobserved in experiment
 . In this talk\, I will present direct observations of the energy excitati
 on spectra of emergent CFTs at quantum phase transitions\, recovering univ
 ersal energy ratios characteristic of the underlying field theories. By us
 ing a variant of the modulation technique\, we furthermore study the dynam
 ical structure factor of the critical system\, which is closely related to
  the correlation of an underlying Ising conformal field.
