"Sensitivity and Stability of Quantum Fluids in Driven Disorder" (Prof. Artur Widera)

Date: Jan 28, 2025
Time: 02:30 PM (Local Time Germany)
Speaker: Prof. Artur Widera
RPTU Kaiserslautern-Landau, Physics Department and State Research Center OPTIMAS, Kaiserslautern, Germany
Location: Max Planck Institute of Quantum Optics, Hans-Kopferman-Straße 1, 85748 Garching
Room: Herbert Walther Lecture Hall

The interplay of local perturbations and interactions is key for understanding quantum many-body systems. We study lithium Fermi gases in time-dependent disorder, using speckle potentials with quenches or finite correlation times. [more]

“Exploring the Limits of Time: From Attosecond Electron Microscopy Imaging To Petahertz Quantum Tunneling and Communication” (Prof. Mohammed Hassan)

Date: Feb 4, 2025
Time: 02:30 PM (Local Time Germany)
Speaker: Prof. Mohammed Hassan
University of Arizona, Tucson, USA
Location: Max Planck Institute of Quantum Optics, Hans-Kopferman-Straße 1, 85748 Garching
Room: Herbert Walther Lecture Hall

We present groundbreaking advancements in ultrafast electron microscopy, quantum current tunneling in graphene, and ultrafast squeezed light, establishing transformative capabilities in attosecond science and technology¹. First, we achieved attosecond temporal resolution in a transmission electron microscope by generating a single isolated attosecond electron pulse, far surpassing the highest reported imaging resolutions^2,3. This novel tool, termed the “attomicroscope,” represents the world’s fastest electron microscope, enabling the imaging and control of electron motion dynamics in graphene. The attosecond electron imaging method offers real-time and spatial insights into the electron motion of neutral matter, unlocking long-anticipated applications in quantum physics, chemistry, and biology³.
