Seminars


Seminars

On an irregular basis various Special Seminars take place at the MPQ. The seminars are organized by scientists of our divisions, administration or staff representatives.

The location will be announced with the event.
OSA presents its actions and programs for the “optics and photonics” community: students, faculty and industry from all over the world. Benefits will be shown for those relating with OSA at various levels, including the journal publishing program, including reviewer policies and rewarding. On demand, a more in depth description of student chapters will be given, its setup, the benefits (not only to students) and how to maintain and develop it. Everybody is welcome (OSA members and non-members). [more]

Probing many-body quantum states with randomized measurements

Probing many-body quantum states with randomized measurements
Randomized measurements are a technique to probe many-body quantum states beyond familiar, low-order observables. In this talk, I introduce the technique using the example of measuring the second-order Rényi entropy in a trapped ion quantum simulator. [more]
Incompatibility in quantum mechanics is famously captured through uncertainty relations. In this talk, we adopt the perspective that incompatibility can be fundamentally understood in terms of emulation of measurements by other measurements. [more]

Simulating ground states and elementary excitations with PEPS (Dr. Laurens Vanderstraeten)

Simulating ground states and elementary excitations with PEPS
In this talk we review variational PEPS algorithms for two-dimensional quantum spin systems. First we focus on the optimization of ground-state approximations for generic hamiltonians, and show some benchmark results. Next, we build excited-state wavefunctions on top of such a PEPS ground state using a generalization of the single-mode approximation. [more]

Ultrafast mid-infrared laser systems and broad-band precision molecular spectroscopy

Ultrafast mid-infrared laser systems and broad-band precision molecular spectroscopy
Femtosecond laser sources operating in the near- and middle-infrared (mid-IR) spectral range with high- repetition rates are of upmost interest for a variety of applications ranging from ultrafast spectroscopy, high-resolution and broadband spectroscopy, quantum optics, frequency metrology and synthesis of mid-IR optical frequency combs.
