Evidence of Two-Source King Plot Nonlinearity in Spectroscopic Search for New Boson
Joonseok Hur, Diana P. L. Aude Craik, Ian Counts +12
Optical precision spectroscopy of isotope shifts can be used to test for new forces beyond the Standard Model, and to determine basic properties of atomic nuclei. We measure isotop…
Evidence for Nonlinear Isotope Shift in Yb Search for New Boson
Ian Counts, Joonseok Hur, Diana P. L. Aude Craik +7
We measure isotope shifts for five Yb isotopes with zero nuclear spin on two narrow optical quadrupole transitions , ${}^2S_{1/2} \rightarr…
Nonlinear, Nonequilibrium and Collective Dynamics in a Periodically Modulated Cold Atom System
Geol Moon, Myoung-Sun Heo, Yonghee Kim +2
The physics of critical phenomena in a many-body system far from thermal equilibrium is an interesting and important issue to be addressed both experimentally and theoretically. Th…
Velocity tuning of friction with two trapped atoms
Dorian Gangloff, Alexei Bylinskii, Ian Counts +2
Friction is the basic, ubiquitous mechanical interaction between two surfaces that results in resistance to motion and energy dissipation. In spite of its technological and economi…
Spontaneous Symmetry Breaking of Population between Two Dynamic Attractors in a Driven Atomic Trap: Ising-class Phase Transition
Kihwan Kim, Myoung-Sun Heo, Ki-Hwan Lee +4
We have observed spontaneous symmetry breaking of atomic populations in the dynamic phase-space double-potential system, which is produced in the parametrically driven magneto-opti…
Noise-induced Transition between Dynamic Attractors in the Parametrically Excited Magneto-optical Trap
Kihwan Kim, Myungsun Heo, Ki-Hwan Lee +4
We have investigated noise-induced transition of atoms between double or triple phase-space attractors that are produced in the parametrically driven magneto-optical trap. The tran…
