Superabsorption of light via quantum engineering [PDF]
, 2014 Almost 60 years ago Dicke introduced the term superradiance to describe a signature quantum effect: N atoms can collectively emit light at a rate proportional to N-2.

Coherent Many-Body Spin Dynamics in a Long-Range Interacting Ising Chain
Physical Review X, 2017 Coherent many-body quantum dynamics lies at the heart of quantum simulation and quantum computation. Both require coherent evolution in the exponentially large Hilbert space of an interacting many-body system. To date, trapped ions have defined the state

Weak-measurement-induced heating in Bose-Einstein condensates
Physical Review Research, 2023 Ultracold atoms are an ideal platform for understanding system-reservoir dynamics of many-body systems. Here, we study quantum back-action in atomic Bose-Einstein condensates, weakly interacting with a far-from resonant, i.e., dispersively interacting ...

Coherent excitation of ultracold atoms between ground and Rydberg states [PDF]
, 2011 This thesis describes the development of an experiment to study coherent population transfer between ground states, and between ground and Rydberg states, in ultracold atoms.

Dynamics of nonequilibrium Dicke models [PDF]
, 2012 Motivated by experiments observing self-organization of cold atoms in optical cavities we investigate the collective dynamics of the associated non-equilibrium Dicke model.

Stochastic series expansion quantum Monte Carlo for Rydberg arrays
SciPost Physics CoreArrays of Rydberg atoms are a powerful platform to realize strongly-interacting quantum many-body systems. A common Rydberg Hamiltonian is free of the sign problem, meaning that its equilibrium properties are amenable to efficient simulation by quantum ...

A Quantum Degenerate Mixture of $^{87}$Rb and $^{133}$Cs [PDF]
, 2011 This thesis reports the formation of a dual-species Bose-Einstein condensate of $^{87}$Rb and $^{133}$Cs in the same trapping potential. Quantum degenerate mixtures exhibit rich physics inaccessible to single species experiments and provide an ideal ...

Long-Lived Spin-Orbit-Coupled Degenerate Dipolar Fermi Gas
Physical Review X, 2016 We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate atoms using the most magnetic fermionic element, dysprosium. Spin-orbit coupling arises from a synthetic gauge field created by the adiabatic following of degenerate ...

Factorization with a logarithmic energy spectrum
New Journal of Physics, 2013 We propose a method to factor numbers based on the quantum dynamics of two interacting bosonic atoms where the single-particle energy spectrum depends logarithmically on the quantum number.

Signatures of Quantum Chaos of Rydberg-Dressed Bosons in a Triple-Well Potential
Atoms, 2023 We studied signatures of quantum chaos in dynamics of Rydberg-dressed bosonic atoms held in a one-dimensional triple-well potential. Long-range nearest-neighbor and next-nearest-neighbor interactions, induced by laser dressing atoms to strongly ...
