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.

DMRG with Subspace Expansion on Symmetry-Protected Tensor Networks (C. Hubig)

The Density Matrix Renormalisation Group when applied to matrix-product states is the method of choice for ground-state search on one-dimensional systems and still highly competitive even in unfavourable circumstances, such as critical systems and higher dimensions. [more]

Quantum optics with semiconductor quantum dots (Prof. P. Senellart-Mardon)

Today, optical quantum technologies are limited both by the low efficiency of heralded single-photon sources and by the probabilistic operation of two-photon gates. [more]

Efficient representation of fully many-body localized systems using tensor networks (Dr. T. Wahl)

Many-body localization (MBL) is currently an intensely studied topic and characterized by the fact that certain strongly disordered systems fail to thermalize. For sufficiently strong disorder in one dimension, all eigenstates of MBL systems fulfill the area law of entanglement. [more]

Silicon-Based Microresonator Frequency Combs (Prof. A. Gaeta)

Microresonator frequency combs have attracted much recent interest due to their potential to enable time and frequency metrology applications in a highly compact and robust platform. [more]

From cold atoms to ultracold molecules: spin‐wave rephasing and ultracold exchange reaction (Dr. Jun Rui)

In this talk, I will introduce the setup that we have built in the past three years to create ultracold 23Na40K molecules from an ultracold atomic mixture gas. [more]
