Emergence of Fermi's Golden Rule in the Probing of a Quantum Many-Body System
Jianyi Chen, Songtao Huang, Yunpeng Ji +5
Fermi's Golden Rule (FGR) is one of the most impactful formulas in quantum mechanics, providing a link between easy-to-measure observables - such as transition rates - and fundamen…
Emergence of Sound in a Tunable Fermi Fluid
Songtao Huang, Yunpeng Ji, Thomas Repplinger +6
Landau's Fermi-liquid (FL) theory has been successful at the phenomenological description of the normal phase of many different Fermi systems. Using a dilute atomic Fermi fluid wit…
The strongly driven Fermi polaron
Franklin J. Vivanco, Alexander Schuckert, Songtao Huang +6
Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. Therefore, the prospect of manipulating their properties wit…
Observation of the Fermionic Joule-Thomson Effect
Yunpeng Ji, Jianyi Chen, Grant L. Schumacher +4
We report the observation of the quantum Joule-Thomson (JT) effect in ideal and unitary Fermi gases. We study the temperature dynamics of these systems while they undergo an energy…
Observation of Anomalous Decay of a Polarized Three-Component Fermi Gas
Grant L. Schumacher, Jere T. Mäkinen, Yunpeng Ji +5
Systems of fermions with multiple internal states, such as quarks in quantum chromodynamics and nucleons in nuclear matter, are at the heart of some of the most complex quantum man…
On the Stability of the Repulsive Fermi Gas with Contact Interactions
Yunpeng Ji, Grant L. Schumacher, Gabriel G. T. Assumpção +4
We report the creation and the study of the stability of a repulsive quasi-homogeneous spin- Fermi gas with contact interactions. For the range of scattering lengths explo…
Analysis of membrane phononic crystals with wide bandgaps and low-mass defects
Chris Reetz, Ran Fischer, Gabriel G. T. Assumpcao +4
We present techniques to model and design membrane phononic crystals with low-mass defects, optimized for force sensing. Further, we identify the importance of the phononic crystal…
Spin detection with a micromechanical trampoline: Towards magnetic resonance microscopy harnessing cavity optomechanics
Ran Fischer, Dylan P. McNally, Chris Reetz +4
We explore the prospects and benefits of combining the techniques of cavity optomechanics with efforts to image spins using magnetic resonance force microscopy (MRFM). In particula…
Optical probing of mechanical loss of a Si_{3}N_{4} membrane below 100 mK
R. Fischer, N. S. Kampel, G. G. T. Assumpção +5
We report on low mechanical loss in a high-stress silicon nitride (Si_{3}N_{4}) membrane at temperatures below 100 mK. We isolate a membrane via a phononic shield formed within a s…
