Steady-state phases in long-range measurement-only quantum circuits
Bihui Zhu
Measurements can drive quantum many-body systems into nontrivial steady states and induce interesting dynamical phase transitions, rendering measurement-only quantum circuits a use…
Unsupervised Learning of Quantum Phase Transitions for Bose-Hubbard lattice systems
Bihui Zhu
Characterizing quantum many-body phase structure is a major goal for quantum simulation. Here, we employ an unsupervised learning approach based on diffusion maps to learn phase tr…
Many-body cavity quantum electrodynamics with driven inhomogeneous emitters
Mi Lei, Rikuto Fukumori, Jake Rochman +4
Quantum emitters coupled to optical resonators are quintessential systems for exploring fundamental phenomena in cavity quantum electrodynamics (cQED) and are commonly used in quan…
Measuring correlations from the collective spin fluctuations of a large ensemble of lattice-trapped dipolar spin-3 atoms
Youssef Aziz Alaoui, Bihui Zhu, Sean Robert Muleady +5
We perform collective spin measurements to study the buildup of two-body correlations between spin chromium atoms pinned in a 3D optical lattice. The spins inte…
Relaxation of the collective magnetization of a dense 3D array of interacting dipolar S=3 atoms
Lucas Gabardos, Bihui Zhu, Steven Lepoutre +3
We report on measurements of the dynamics of the collective spin length (total magnetization) and spin populations in an almost unit filled lattice system comprising about 10^4 spi…
Dynamics of an itinerant spin-3 atomic dipolar gas in an optical lattice
Petra Fersterer, Arghavan Safavi-Naini, Bihui Zhu +6
Arrays of ultra-cold dipolar gases loaded in optical lattices are emerging as powerful quantum simulators of the many-body physics associated with the rich interplay between long-r…
A generalized phase space approach for solving quantum spin dynamics
Bihui Zhu, Ana Maria Rey, Johannes Schachenmayer
Numerical techniques to efficiently model out-of-equilibrium dynamics in interacting quantum many-body systems are key for advancing our capability to harness and understand comple…
Controlling Dipolar Exchange Interactions in a Dense 3D Array of Large Spin Fermions
A. Patscheider, B. Zhu, L. Chomaz +5
Dipolar interactions are ubiquitous in nature and rule the behavior of a broad range of systems spanning from energy transfer in biological systems to quantum magnetism. Here, we s…
Dicke time crystals in driven-dissipative quantum many-body systems
Bihui Zhu, Jamir Marino, Norman Y. Yao +2
The Dicke model -- a paradigmatic example of superradiance in quantum optics -- describes an ensemble of atoms which are collectively coupled to a leaky cavity mode. As a result of…
Shattered Time: Can a Dissipative Time Crystal Survive Many-Body Correlations?
Kristopher Tucker, Bihui Zhu, Robert J. Lewis-Swan +4
We investigate the emergence of a time crystal in a driven-dissipative many-body spin array. In this system the interplay between incoherent spin pumping and collective emission st…
Exploring out-of-equilibrium quantum magnetism and thermalization in a spin-3 many-body dipolar lattice system
S. Lepoutre, J. Schachenmayer, L. Gabardos +7
Understanding quantum thermalization through entanglement build-up in isolated quantum systems addresses fundamental questions on how unitary dynamics connects to statistical physi…
Cavity Mediated Collective Spin Exchange Interactions in a Strontium Superradiant Laser
Matthew A. Norcia, Robert J. Lewis-Swan, Julia R. K. Cline +3
Laser cooled and quantum degenerate atoms are widely being pursued as quantum simulators that may explain the behavior of strongly correlated material systems, and as the basis of…
Spin mixing and protection of ferromagnetism in a spinor dipolar condensate
S. Lepoutre, K. Kechadi, B. Naylor +7
We study spin mixing dynamics in a chromium dipolar Bose-Einstein Condensate, after tilting the atomic spins by an angle with respect to the magnetic field. Spin mixing is trig…
