Abstract: Ultrafast infrared spectroscopy in its extension to nano-imaging provides access to vibrational and low energy carrier dynamics in molecular, semiconductor, quantum, or polaritonic materials. In addition, to simultaneously probe both ground and excited state dynamics we have developed ultrafast heterodyne pump-probe nano-imaging with far-from-equilibrium excitation.
Abstract: Quantum processors have the potential to significantly advance our understanding of quantum systems. In particular, the programmability of digital quantum devices can enable access to highly tunable quantum dynamics and observables. The central challenge, however, is suppressing errors, making quantum error correction essential for large-scale algorithms.
Abstract: Optical tweezer arrays of laser-cooled molecules are an emerging platform for quantum science, combining the rich internal structure of molecules with the versatile microscopic control and detection capabilities of optical tweezers. In recent years, our lab has helped push the frontier of quantum control in this platform, demonstrating high-fidelity single-molecule imaging and state preparation, coherent control at both the single and two molecule level, and deterministic entanglement between individually prepared molecules.
Abstract: The evolution of plasma environments is defined and governed by balances between ionizing processes, chemical rearrangements, and neutralisation reactions such as mutual neutralisation (MN). Measuring and explaining these processes in detail is fundamental to understanding and modelling non-local thermal equilibrium environments, such as atmospheric plasmas.
Please join us Monday, July 14 for a talk from Cornell group visitor Heleen Mulder. Heleen is a PhD student working on theoretical particle physics with Jordy de Vries at Nikhef in Amsterdam and a member of the NLeEDM collaboration.
Fermionic quantum simulators provide a powerful platform for exploring high-temperature superconductivity, topological phases, and many-body dynamics—challenges that persist even with the advent of qubit-based quantum computing. In this talk, I will present recent results from our high-repetition-rate fermionic quantum gas microscope, which is optimized for rapid data acquisition. Fast cycle times on the order of a few seconds are achieved through high-power optical traps, rapid evaporative cooling, and efficient spin-resolved fluorescence imaging.
Long-lived optical clock states of alkaline earth and alkaline earth-like atoms have many applicati
Ultracold polar molecules possess inherent strong electric dipole moments and a rich internal structure, making them ideal platforms for implementing novel quantum information schemes, performing precision quantum metrology, and exploring exotic quantum phases such as dipolar BEC-BCS crossover in molecular Fermi gases. However, such experiments require extensive control over two or more species of atoms and their interactions, significantly scaling up the complexity and construction period of the experiment setup.
