Dynamic polarizability measurements in Lu
K. J. Arnold, R. Kaewuam, T. R. Tan +3
We measure the differential polarizability of the Lu -to- clock transition at multiple wavelengths. This experimentally characterizes the differential…
Nobelium energy levels and hyperfine structure constants
S. G. Porsev, M. S. Safronova, U. I. Safronova +2
Advances in laser spectroscopy of superheavy () elements enabled determination of the nuclear moments of the heaviest nuclei, which requires high-precision atomic calculatio…
Optical clock comparison test of Lorentz symmetry
Christian Sanner, Nils Huntemann, Richard Lange +4
Questioning the presumably most basic assumptions about the structure of space and time has revolutionized our understanding of Nature. State-of-the-art atomic clocks make it possi…
Bose Condensation of Photons Thermalized via Laser Cooling of Atoms
Chiao-Hsuan Wang, M. J. Gullans, J. V. Porto +2
A Bose-Einstein condensate (BEC) is a quantum phase of matter achieved at low temperatures. Photons, one of the most prominent species of bosons, do not typically condense due to t…
Challenges to miniaturizing cold atom technology for deployable vacuum metrology
Stephen Eckel, Daniel S. Barker, James A. Fedchak +3
Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of…
A low-steering piezo-driven mirror
E. Magnan, J. Maslek, C. Bracamontes +3
We present a piezo-driven translatable mirror with excellent pointing stability, capable of driving at frequencies up to tens of kilohertz. Our system uses a tripod of piezo actuat…
Nuclear charge radii of Th from isotope and isomer shifts
M. S. Safronova, S. G. Porsev, M. G. Kozlov +5
The isotope Th is unique in that it possesses an isomeric state of only a few eV above the ground state, suitable for nuclear laser excitation. An optical clock based on th…
Clock-related properties of Lu+
S. G. Porsev, U. I. Safronova, M. S. Safronova
The singly-ionized lutetium has a number of fortuitous properties well suited for a design of an optical clock and corresponding applications. In this work, we study Lu+ properties…
Orbital quantum magnetism in spin dynamics of strongly interacting magnetic lanthanide atoms
Ming Li, Eite Tiesinga, Svetlana Kotochigova
Laser cooled lanthanide atoms are ideal candidates with which to study strong and unconventional quantum magnetism with exotic phases. Here, we use state-of-the-art closed-coupling…
Imaging topology of Hofstadter ribbons
Dina Genkina, Lauren M. Aycock, Hsin-I Lu +3
Physical systems with non-trivial topological order find direct applications in metrology[1] and promise future applications in quantum computing[2,3]. The quantum Hall effect deri…
Spectral Asymmetry of Atoms in the van der Waals Potential of an Optical Nanofiber
B. D. Patterson, P. Solano, P. S. Julienne +2
We measure the modification of the transmission spectra of cold Rb atoms in the proximity of an optical nanofiber (ONF). Van der Waals interactions between the atoms an the…
Two clock transitions in neutral Yb for the highest sensitivity to variations of the fine-structure constant
M. S. Safronova, S. G. Porsev, Christian Sanner +1
We propose a new frequency standard based on a transition in neutral Yb. This transition has a potential for high stability and acc…
