Observation of discrete time-crystalline order in a disordered dipolar many-body system
Soonwon Choi, Joonhee Choi, Renate Landig +11
Understanding quantum dynamics away from equilibrium is an outstanding challenge in the modern physical sciences. It is well known that out-of-equilibrium systems can display a ric…
Nonvolatile quantum memory enables sensor unlimited nanoscale spectroscopy of finite quantum systems
Matthias Pfender, Nabeel Aslam, Hitoshi Sumiya +5
In nanoscale metrology applications, measurements are commonly limited by the performance of the sensor. Here we show that in nuclear magnetic resonance (NMR) spectroscopy measurem…
Critical thermalization of a disordered dipolar spin system in diamond
Georg Kucsko, Soonwon Choi, Joonhee Choi +10
Statistical mechanics underlies our understanding of macroscopic quantum systems. It is based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium s…
Depolarization dynamics in a strongly interacting solid-state spin ensemble
Joonhee Choi, Soonwon Choi, Georg Kucsko +9
We study the depolarization dynamics of a dense ensemble of dipolar interacting spins, associated with nitrogen-vacancy centers in diamond. We observe anomalously fast, density-dep…
Collective Strong Coupling with Homogeneous Rabi Frequencies using a 3D Lumped Element Microwave Resonator
Andreas Angerer, Thomas Astner, Daniel Wirtitsch +5
We design and implement 3D lumped element microwave cavities for the coherent and uniform coupling to electron spins hosted by nitrogen vacancy centers in diamond. Our design spati…
Ultrathin fiber-taper coupling with nitrogen vacancy centers in nanodiamonds at cryogenic temperatures
Masazumi Fujiwara, Hong-Quan Zhao, Tetsuya Noda +3
We demonstrate cooling of ultrathin fiber tapers coupled with nitrogen vacancy (NV) centers in nanodiamonds to cryogenic temperatures. Nanodiamonds containing multiple NV centers a…
