Нови SCL семинар Центра за студије комплексних система биће одржан на Институту за физику у Београду у четвртак, 29. марта у 14 часова у читаоници библиотеке „Др Драган Поповић“. Предавање под насловом:
N-point functions mapping for dissipative quantum systems
ће одржати др Етиен Вамба (Хумболтов стипендиста, Департман за физику, Технички универзитет Кајзерслаутерн, Немачка)
АПСТРАКТ:
Motivated by recent experimental efforts for achieving and controlling dissipative quantum systems, in this talk we will consider a D-dimensional quantum gas that interacts with a bath and evolves according to a Lindblad master equation. Invoking the picture independence of expectation values and using the quantum fields that describe the gas dynamics, we will derive the Heisenberg evolution of any arbitrary N-point function of the system in the regime when the Lindblad generators feature a loss or gain. Our quantum field mapping [1] for closed quantum systems will be extended to open quantum systems by relating onto each other two different evolutions of the N-point functions of the dissipative quantum system.
