Join an evening of fun with your family and colleagues before the academic year begins! The event includes carnival games and inflatables, free food, music, wellness resources, and free backpacks with school supplies (limited).
Abstract: In this talk, I’ll discuss a new framework to simulate the open dynamics of many-boson quantum systems. We use a superposition of squeezed-displaced states as a non-Gaussian state (NGS) ansatz. It is not restricted to a low excitation subspace, and can describe a variety of interesting quantum states (eg. squeezed cat states).
Note: Feel free to bring your own lunch.
Each year, the Richard Nelson Thomas Award is given to an outstanding APS graduate student at JILA. This year’s recipient is Tatsuya Akiba (of Ann-Marie Madigan’s group).
Please join us in congratulating Tatsuya by attending this celebration! All JILAns are welcome!
There will be refreshments.
Abstract: Models of rotating black holes generally possess not only an event horizon, which marks the point of no return, but also an inner horizon, beyond which lies an observable singularity and potentially a wormhole to a new universe. However, if any matter or radiation falls into the black hole, these sources of accretion will trigger an instability that may destroy the inner horizon and anything beyond.
Abstract: Science faces an accessibility challenge. Although information/knowledge is fast becoming available to everyone around the world, the experience of science is significantly limited. One approach to solving this challenge is to democratize access to scientific tools. We believe this can be achieved via “Frugal science”; a philosophy that inspires design, development and deployment of ultra-affordable yet powerful scientific tools for the masses.
Neutral atoms have emerged in recent years as a leading qubit candidate for quantum computing. Atom interferometers, meanwhile, provide precise measurements of very weak gravitational forces. Both of these applications use optical fields to write-in / read-out information, as well as to trap and manipulate the atoms. Optical resonators have been used to enhance such atom-photon interactions, constituting the field of cavity quantum electrodynamics (QED).
Atom interferometers are exquisite sensors that have been used to perform inertial measurements with ever increasing precision. However, many worthy scientific endeavors present dynamically harsh environments and strict SWaP requirements that are challenging to accommodate for conventional atom interferometers. In this defense, I present the novel approach of Bloch-band interferometry, which confines Bose-condensed atoms to a multidimensional optical lattice for the entire interferometer sequence.
In quantum materials, function follows form: the collective behavior of a large ensemble of electrons crucially depends on the structure of the ionic crystal they inhabit. Ultracold fermionic atoms in optical lattices are a unique platform to understand such emergent phenomena by providing a very clean realization of the Hubbard model, one of the most fundamental models describing strongly correlated quantum matter. Yet, realizing and probing structures inspired by solid-state materials is a challenge beyond simple square geometries.
