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.


Laboratory study of interstellar ion-polar molecule reactions (Prof. K. Okada)

Ion-molecule reactions play important roles in the production processes of interstellar molecules in molecular clouds. In this seminar, I will present the recent experimental data on the translational and rotational temperature dependence of the reaction-rate constant in the CH3CN-Ne+ reaction system. [more]

Nonlinear Optics with Rydberg Excitons (V. Walther)

The realization of exciton polaritons -- hybrid excitations of semiconductor quantum well excitons and cavity photons -- has been of great technological and scientific significance. [more]

A programmable quantum computer based on trapped ions (Dr. N. Linke)

Trapped ions are a promising candidate system to realize a scalable quantum computer. We present a modular quantum computing architecture comprised of a chain of 171Yb+ ions with individual Raman beam addressing and individual readout. [more]

Entanglement Hamiltonians from field theory to the lattice (G. Giudici)

Given a space bipartition (A, B) of a quantum state, the entanglement Hamiltonian of A is the logarithm of the reduced density matrix obtained after tracing over B. [more]
