The realization of large-scale controlled quantum systems is an exciting frontier in modern physical science. In this talk, I will introduce a new approach based on cold atoms in arrays of optical tweezers. We use atom-by-atom assembly to deterministically prepare arrays of individually controlled cold atoms.

## Special Seminar

### Special Seminar: Hannes Bernien, Harvard; "Quantum LEGOs: Building large quantum systems atom-by-atom"

### High Energy Physics Experimental Seminar-Erica Brondolin-UNIMIB-"Track reconstruction in the CMS experiment for the High Luminosity LHC"

" The CMS experiment is in the process of designing a completely new track detector for the high-luminosity phase of LHC. The results of the future offline tracking performance of CMS will be presented, such as the excellent efficiency and the very good track separation in the core of a jet.

### Class Day - Meet and mingle with the graduates and their parents.

### Physics Group Meeting | Pavel Putrov, Member, School of Natural Sciences, IAS | “Link Invariants and Topological Quantum Matter”

Gauging of bosonic and fermionic symmetry protected topological (SPT) states with discrete symmetry produces simple yet non-trivial topological quantum field theories (TQFTs). Some of the natural observables in such TQFTs are expectation values of line and surface operators linked in space-time.

### Next-generation atomic clocks - G. Edward Marti, JILA

Abstract: The accuracy of atomic clocks has improved a thousandfold over the last 15 years, driven by improvements in ultrastable lasers, quantum control, and our understanding of atomic interactions.

### New quantum phases of matter in strongly correlated and spin-orbit-coupled metals - John Harter, Caltech

Strong interactions between electrons are known to drive metallic systems toward a variety of well-known symmetry-broken phases, including superconducting, electronic liquid crystalline, and charge- and spin-density wave ordered states. In contrast, the electronic instabilities of correlated metals with strong spin-orbit coupling have only...

### Physics Group Meeting | Matias Zaldarriaga, Faculty, School of Natural Sciences, IAS | “Discussion of MOND and LCDM”

I will review the phenomenological successes of MOND on the scale of galaxies. I will discuss its failure on cosmological scales. These large scale problems have been understood for decades, are very robust and their origin can be easily understood. On the scales of galaxies, rotation curves are well described by the MOND force law without any...

### Probing Topological Valley Physics in Bilayer Graphene - Long Ju, Cornell University

Graphene has been a model solid state system where novel quantum phenomena emerge from the interplay between symmetry, band topology and reduced dimensionality. In particular, AB-stacked bilayer graphene has a unique bandstructure with an electrically tunable bandgap and a valley-dependent Berry phase.
