Long-lived coherences in strongly interacting spin ensembles
William K. Schenken, Simon A. Meynell, Francisco Machado +6
Periodic driving has emerged as a powerful tool to control, engineer, and characterize many-body quantum systems. However, the required pulse sequences are often complex, long, or…
Quantum noise spectroscopy of dynamical critical phenomena
Francisco Machado, Eugene A. Demler, Norman Y. Yao +1
The transition between distinct phases of matter is characterized by the nature of fluctuations near the critical point. We demonstrate that noise spectroscopy can not only diagnos…
Universal Kardar-Parisi-Zhang dynamics in integrable quantum systems
Bingtian Ye, Francisco Machado, Jack Kemp +2
Although the Bethe ansatz solution of the spin-1/2 Heisenberg model dates back nearly a century, the anomalous nature of its high-temperature transport dynamics has only recently b…
Absolutely stable time crystals at finite temperature
Francisco Machado, Quntao Zhuang, Norman Y. Yao +1
We show that locally-interacting, periodically-driven (Floquet) Hamiltonian dynamics coupled to a Langevin bath support finite-temperature discrete time crystals (DTC) with an infi…
Observation of a many-body-localized discrete time crystal with a programmable spin-based quantum simulator
J. Randall, C. E. Bradley, F. V. van der Gronden +7
The discrete time crystal (DTC) is a recently discovered phase of matter that spontaneously breaks time-translation symmetry. Disorder-induced many-body-localization is required to…
Quantum gas microscopy of Kardar-Parisi-Zhang superdiffusion
David Wei, Antonio Rubio-Abadal, Bingtian Ye +9
The Kardar-Parisi-Zhang (KPZ) universality class describes the coarse-grained behavior of a wealth of classical stochastic models. Surprisingly, it was recently conjectured to also…
Emergent hydrodynamics in a strongly interacting dipolar spin ensemble
Chong Zu, Francisco Machado, Bingtian Ye +12
Conventional wisdom holds that macroscopic classical phenomena naturally emerge from microscopic quantum laws. However, despite this mantra, building direct connections between the…
Floquet Phases of Matter via Classical Prethermalization
Bingtian Ye, Francisco Machado, Norman Y. Yao
We demonstrate that the prethermal regime of periodically driven (Floquet), classical many-body systems can host nonequilibrium phases of matter. In particular, we show that there…
Probing many-body dynamics in a two dimensional dipolar spin ensemble
Emily J. Davis, Bingtian Ye, Francisco Machado +13
The most direct approach for characterizing the quantum dynamics of a strongly-interacting system is to measure the time-evolution of its full many-body state. Despite the conceptu…
Observation of a prethermal discrete time crystal
Antonis Kyprianidis, Francisco Machado, William Morong +9
The conventional framework for defining and understanding phases of matter requires thermodynamic equilibrium. Extensions to non-equilibrium systems have led to surprising insights…
Emergent ergodicity at the transition between many-body localized phases
Rahul Sahay, Francisco Machado, Bingtian Ye +2
Strongly disordered systems in the many-body localized (MBL) phase can exhibit ground state order in highly excited eigenstates. The interplay between localization, symmetry, and t…
Long-Range Prethermal Phases of Nonequilibrium Matter
Francisco Machado, Dominic V. Else, Gregory D. Kahanamoku-Meyer +2
We prove the existence of non-equilibrium phases of matter in the prethermal regime of periodically-driven, long-range interacting systems, with power-law exponent , where $d…
Emergent hydrodynamics in non-equilibrium quantum systems
Bingtian Ye, Francisco Machado, Christopher David White +2
A tremendous amount of recent attention has focused on characterizing the dynamical properties of periodically driven many-body systems. Here, we use a novel numerical tool termed…
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…
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…
Exponentially Slow Heating in Short and Long-range Interacting Floquet Systems
Francisco Machado, Gregory D. Meyer, Dominic V. Else +2
We analyze the dynamics of periodically-driven (Floquet) Hamiltonians with short- and long-range interactions, finding clear evidence for a thermalization time, , that increas…
An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations
Paul Torrey, Sarah Wellons, Francisco Machado +9
The cumulative comoving number-density of galaxies as a function of stellar mass or central velocity dispersion is commonly used to link galaxy populations across different epochs.…
