El grupo de Física Estadística de los Sistemas Complejos les invita al siguiente seminario online: 


Ponente: Francisco Perez-Bernal. Universidad de Huelva. 

Título: Speck of Chaos

Resumen: Local perturbations can bring an integrable quantum many-body system to the chaotic regime. This fact has been known for the XXZ model since 2004, and such results have been recently extended to two other models: the transverse-field Ising chain and the Lai-Sutherland spin 1 chain. The nature of different quantum chaos indicators, static and dynamic, will be reviewed, to discuss how a single local effect can bring three different integrable systems to the chaotic regime. Among the possible indicators, the distribution of off-diagonal matrix elements of local operators and the correlation hole will be presented with more detail.  

Fecha y hora: Viernes 26 de Marzo de 2021. 12 horas.
