Imaging stress and magnetism at high pressures using a nanoscale quantum sensor
S. Hsieh, P. Bhattacharyya, C. Zu +15
Pressure alters the physical, chemical and electronic properties of matter. The development of the diamond anvil cell (DAC) enables tabletop experiments to investigate a diverse la…
Time crystals in periodically driven systems
Norman Y. Yao, Chetan Nayak
When the discrete time-translation symmetry of isolated, periodically driven systems is spontaneously broken, a new phase of matter can emerge. We review some recent developments o…
An improved Lieb-Robinson bound for many-body Hamiltonians with power-law interactions
Dominic V. Else, Francisco Machado, Chetan Nayak +1
In this work, we prove a new family of Lieb-Robinson bounds for lattice spin systems with long-range interactions. Our results apply for arbitrary -body interactions, so long as…
Imaging the local charge environment of nitrogen-vacancy centers in diamond
Thomas Mittiga, Satcher Hsieh, Chong Zu +8
Characterizing the local internal environment surrounding solid-state spin defects is crucial to harnessing them as nanoscale sensors of external fields. This is especially germane…
Probing scrambling using statistical correlations between randomized measurements
Benoît Vermersch, Andreas Elben, Lukas M. Sieberer +2
We propose and analyze a protocol to study quantum information scrambling using statistical correlations between measurements, which are performed after evolving a quantum system f…
Detection and characterization of Many-Body Localization in Central Spin Models
Daniel Hetterich, Norman Y. Yao, Maksym Serbyn +2
We analyze a disordered central spin model, where a central spin interacts equally with each spin in a periodic one dimensional random-field Heisenberg chain. If the Heisenberg cha…
Verified Quantum Information Scrambling
Kevin A. Landsman, Caroline Figgatt, Thomas Schuster +4
Quantum scrambling is the dispersal of local information into many-body quantum entanglements and correlations distributed throughout the entire system. This concept underlies the…
Disentangling Scrambling and Decoherence via Quantum Teleportation
Beni Yoshida, Norman Y. Yao
Out-of-time-order correlation (OTOC) functions provide a powerful theoretical tool for diagnosing chaos and the scrambling of information in strongly-interacting, quantum systems.…
Classical Discrete Time Crystals
Norman Y. Yao, Chetan Nayak, Leon Balents +1
The spontaneous breaking of time-translation symmetry in periodically driven quantum systems leads to a new phase of matter: discrete time crystals (DTC). This phase exhibits colle…
