Immanuel Bloch (MPI – Quantum Optics)

When:
November 20, 2019 @ 4:00 pm – 5:00 pm

This is a special seminar (Wednesday instead of Friday) held in SCGP (Simons Center) room 102.  It is jointly hosted by AMO, Condensed Matter, and the SCGP.

speaker: Immanuel Bloch (Max Planck Institute for Quantum Optics, Garching)

title: Quantum Matter under the Microscope

abstract: More than 30 years ago, Richard Feynman outlined his vision of a quantum simulator for carrying out complex calculations on physical problems. Today, his dream is a reality in laboratories around the world. This has become possible by using complex experimental setups of thousands of optical elements, which allow atoms to be cooled to nanokelvin temperatures, where they almost come to rest. Recent experiments with quantum gas microscopes allow for an unprecedented view and control of such artificial quantum matter in new parameter regimes and with new probes. In our fermionic quantum gas microscope, we can detect both charge and spin degrees of freedom simultaneously, thereby gaining maximum information on the intricate interplay between the two in the paradigmatic Hubbard model. In my talk, I will show how we can reveal hidden magnetic order, directly image individual magnetic polarons or probe the fractionalisation of spin and charge in dynamical experiments. For the first time we thereby have access to directly probe non-local ‘hidden’ correlation properties of quantum matter and to explore its real space resolved dynamical features also far from equilibrium. Furthermore, I will show how quantum gas microscopy can open new avenues for the field of quantum chemistry when probing and controlling the formation of huge Rydberg macrodimers in optical lattices.
