A01.00001: Davisson-Germer Prize in Atomic or Surface Physics: Exciting 1D Bose gases Invited Speaker: David S. Weiss Experiments with nearly integrable quantum systems taken out of equilibrium have made clear that conventional statistical mechanics does not always describe the steady state of an isolated many-body system. These experiments have deepened our understanding of what it means for any quantum system to thermalize. I will briefly explain the two previous sentences and then touch on the frontier of experiment and theory in out-of-equilibrium nearly integrable many-body quantum systems, focusing on our work with 1D Bose gases. |

A01.00002: Prize for a Faculty Member for Research in an Undergraduate Institution: Tests of Fundamental Physics at the Tabletop's Edge Invited Speaker: Derek F Jackson Kimball Our undergraduate research program at Cal State East Bay is reviewed, where the tools of atomic physics are used to carry out precision tests of fundamental physics. Our relatively small-scale, "table-top" experiments search for long-range spin-mass (spin-gravity) interactions, evidence of ultralight bosonic dark matter, and anomalous signals from cataclysmic astrophysical events. The focus of our recent work has been organizing the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), a worldwide network of time-synchronized atomic magnetometers searching for correlated signals due to ultralight bosonic fields. Future research involves the development of a new class of detectors: Levitated Ferromagnetic Torque Sensors (LeFTS). Micron-scale ferromagnets, if sufficiently isolated from the environment, are predicted to display gyroscopic behavior due to their polarized electron spins. Rapid averaging of quantum uncertainty enables LeFTS, in principle, to probe exotic spin-dependent interactions with far greater sensitivity than existing methods. These table-top experiments are ideal for mentorship of undergraduate students. Students are involved in all aspects of the work: from planning, design, and construction of the apparatus to data acquisition and analysis. Cal State East Bay is one of the most diverse universities in the United States, and so our program has provided an entry point into physics research for underserved students from a wide variety of backgrounds. |

A01.00003: Norman F. Ramsey Prize in Atomic, Molecular and Optical Physics, and in Precision Tests of Fundamental Laws and Symmetries: Exploring new scientific frontiers with programmable quantum systems Invited Speaker: Mikhail Lukin We will discuss the recent advances involving programmable, coherent manipulation of quantum many-body systems using neutral atom arrays excited into Rydberg states, allowing the control over 200 qubits in two dimensions. These systems are used for realization of exotic quantum phases of matter and exploration of their non-equilibrium dynamics. In particular, we will describe realization and probing of quantum spin liquid states - the exotic topological states of matter have thus far evaded direct experimental detection. Recent advances involving observation of quantum speedup for solving optimization problems and the realization of novel quantum processing architecture based on dynamically reconfigurable entanglement will be described. Prospects for using these techniques for realization of large-scale quantum processors and quantum simulators will be discussed. |

A01.00004: Breakthrough Prize in Fundamental Physics: Making optical lattice clocks compact and useful for real-world applications Invited Speaker: Hidetoshi Katori An “optical lattice clock” proposed in 2001 benefits from a low quantum-projection noise by simultaneously interrogating many atoms trapped in an optical lattice. The essence of the proposal was an engineered perturbation based on the “magic wavelength” protocol, which has been proved successful up to 10-18 uncertainty. About a thousand atoms enable such clocks to achieve 10-18 stability in a few hours of operation. This superb stability is especially beneficial for chronometric leveling, which determines a centimeter height difference of far distant sites by the gravitational redshift of the clocks. |

A01.00005: Breakthrough Prize in Fundamental Physics: Quantum matter, clock, and fundamental physics Invited Speaker: Jun Ye Precise control of quantum states of matter and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to explore emerging phenomena and probe fundamental physics. Recent advances include measurements of the gravitation time dilation across a mm-scale atomic ensemble. |
