Stanley "Alex" Breitweiser (University of Pennsylvania)

Condensed and Living Matter Seminar: "Self-propelled particles"

Hartmut Löwen (Heinrich-Heine-Universität Düsseldorf)

Ordinary materials are "passive" in the sense that their constituents are typically made by inert particles which are subjected to thermal fluctuations, internal interactions and external fields but do…

Thesis Defense: “Nonlinear Optical Studies on Two-Dimensional Antiferromagnets and Topological Materials”

Zhuoliang Ni (University of Pennsylvania)

Franklin Institute Award lecture: "Stacking van der Waals Atomic Layers: Quest for New Quantum Materials"

Philip Kim (Harvard University)

Modern electronics rely heavily on technology that confines electrons in the interface layers of semiconductors. In recent years, scientists have discovered that they can isolate various atomically thin van der Waals…

Condensed and Living Matter Seminar: "Unique transport signatures in magnetic materials: Connecting semiclassics and quantum perturbation theory at nonlinear order"

Tobias Holder (Weizmann Institute of Science)

In the last few years, nonlinear responses have become increasingly important for the study and characterization of quantum materials, with the nonlinear anomalous Hall conductivity and…

High Energy Joint Theory/Experiment seminar: "Quantum Technologies for New-physics Searches in the Laboratory and in Space"

Marianna Safronova (University of Delaware)

The extraordinary advances in quantum control of matter and light have been transformative for atomic and molecular precision measurements enabling probes of the most basic laws of Nature to gain a…

High Energy Theory seminar: "Finding True Love"

Horng Sheng Chia (Institute of Advanced Study)

Gravitational wave observations offer unique probes onto the nature of astrophysical bodies in coalescing binary systems. As a binary approaches merger, its dynamics is sensitive to the tidal…
