Over the last 20 years, we have discovered that we live in a molecular Universe: A Universe with a rich and varied organic inventory; A Universe where molecules are abundant and widespread; A Universe where molecules play a central role in key processes that dominate the structure and evolution of galaxies. A Universe where molecules provide convenient thermometers and barometers to probe local physical conditions.

The behavior of the doped Hubbard model at low temperatures is a central problem in modern condensed matter physics, with relevance to correlated materials such as cuprate superconductors. Despite extensive computational studies, many open questions remain on its low-temperature phase diagram, motivating its study through quantum simulation with ultracold fermionic atoms in optical lattices. Here, leveraging a recent several-fold reduction in experimental temperatures, we report the first direct experimental observation of the pseudogap metal in the Hubbard model.

In this workshop, you will learn how to tailor your research for different audiences. It will provide you with skills to present your work for job interviews in academia and industry. You will also learn how to apply these communication skills to the public and have the opportunity to practice with feedback from trained experts in science communication. All JILAns are welcome to attend.

The workshop is two hours total and will be offered twice: 
Option 1: Wednesday November 12, 10am-12pm in JILA X325
Option 2: Thursday November 13, 2-4pm in JILA X317

Edwards Vacuum will be providing a training on Ultra-high Vacuum (UHV) best practices, including best known methods on pump configuration, bake-out, etc.  The goal is to help align UHV best practices department wide to reduce experiment set-up time and re-work. This could also apply to those that do not use UHV today, but may like to take advantage of broadening their UHV knowledge for the future.

Abstract: Fault-tolerant quantum computation requires further advances in lowering physical qubit error rates in scalable architectures. In this talk, I will present our work on superconducting quantum devices to reduce error rates and resource overheads in processors.  I will discuss how defects and interfaces in silicon limit superconducting qubit performance. I will present our discovery of interface piezoelectricity at a superconductor-silicon junction and the impact of this effect on superconducting qubits.

Abstract: Engineered quantum systems, encompassing artificial mesoscopic structures governed by the principles of quantum mechanics, represent a cornerstone of modern quantum science. Notable examples include superconducting circuits, ultracold trapped atoms and ions, as well as electro and optomechanical systems. These systems are not only fascinating from a fundamental physics perspective but also serve as essential building blocks for technological applications.

Please join us for a JAGS Industry Spotlight Seminar featuring Micron. A networking session with the speaker will take place at 12:30pm followed by a technical presentation about the ongoing projects. 

Many-body localization (MBL) is a many-body quantum phenomenon that fails to thermalize under strong disorder. While experimental work on optical lattice systems suggests the existence of a MBL phase in 2D, there have been challenges regarding its existence in two dimensions. The main challenge of MBL in higher dimensions is an avalanche instability: rare regions of weak disorder can act as a thermal bath, which eventually thermalizes the entire system.

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.
