Speaker's Brief Introduction： Silke Paschen is an experimental condensed matter physicist working on strongly correlated electron systems. After her graduation at the Graz University of Technology, her PhD at EPFL Lausanne and research stays at ETH Zurich, the Max Planck Institute for Chemical Physics of Solids in Dresden and Nagoya University, she was appointed full professor of physics at the Vienna University of Technology, with a dual appointment with Rice University since 2017. She is an APS Fellow and recipient of two ERC Advanced Grants. Her research portfolio includes quantum criticality, strange metal behavior, and correlation-driven topological phases, with focus on heavy fermion compounds and related quantum materials. Her team uses a wide spectrum of experimental techniques, from materials synthesis to advanced physical property measurements under multiple extreme conditions. An emerging theme is the use of novel quantum information-inspired tools to probe the peculiar quantum nature in such materials.
Abstract: Entanglement is one of the most striking – and potentially most useful – phenomena in quantum physics. Over the past century, we’ve witnessed remarkable progress: from the discovery of the quantum nature of matter to the precise control and utilization of quantum states across a variety of platforms, with entanglement playing a pivotal role. Curiously, however, these advances have largely stalled at the doorstep of quantum materials – systems governed by the intricate interplay of multiple quantum degrees of freedom, and likely shaped in essential ways by their entanglement structure. In this talk, I will discuss recent developments in this field, focusing on the enigmatic “strange metal” state, which is uniquely suited to make progress.
