First-order phase transition in atom-molecule quantum degenerate mixtures with coherent three-body recombination
G. A. Bougas, A. Vardi, H. R. Sadeghpour +2
We map the phase diagram of a two-mode atom-molecule Bose-Einstein condensate with Fano-Feshbach and coherent three-body recombination (cTBR) terms. The standard second order phase…
Observation of spin singlet butterfly Rydberg molecules in an ultracold atomic Rb gas
Markus Exner, Rohan Srikumar, Richard Blättner +4
We report the observation of spin-singlet ultra-long range Rydberg butterfly molecules consisting of a ground-state atom bound to a Rydberg atom by -wave scattering of Rb…
Anisotropic and non-additive interactions of a Rydberg impurity in a quantum bath
Aileen A. T. Durst, Seth T. Rittenhouse, H. R. Sadeghpour +1
We present a framework for treating anisotropic and non-additive impurity-bath interactions - features that are ubiquitous in realistic quantum impurity problems, but are often neg…
Observation of resonant monopole-dipole energy transfer between Rydberg atoms and polar molecules
J. Zou, R. R. W. Wang, R. González-Férez +2
Resonant energy transfer (RET), between equal parity 1s65s and 1s66s Rydberg levels in helium has been observed in low-temperature ( mK) col…
Reconfigurable Four-Photon Interference among Three Nodes on a Field Deployed Metropolitan Fiber Network
Kazi Reaz, Md Mehdi Hassan, Jacob E. Humberd +7
Advanced quantum networking protocols beyond bi-photon, point-to-point links rely critically on the ability to perform multi-photon interference across multiple nodes under realist…
Signatures of rigidity and second sound in dipolar supersolids
G. A. Bougas, T. Bland, H. R. Sadeghpour +1
We propose a dynamical protocol to probe the rigidity and phase coherence of dipolar supersolids by merging initially separated fragments in quasi-one-dimensional (1D) double-well…
Precision measurement of Cs() quantum defects and calculations of scalar and tensor polarizabilities of the , , , and series
Pinrui Shen, Mariusz Pawlak, Donald Booth +4
In this paper, we extend our recent work on cesium S and D states [Phys. Rev. Lett. 133, 233005 (2024)] to the F states. We present absolute frequency measurements of the $|6S_{1/2…
Competition of light- and phonon-dressing in microwave-dressed Bose polarons
G. M. Koutentakis, S. I. Mistakidis, F. Grusdt +2
We theoretically investigate the stationary properties of a spin-1/2 impurity immersed in a one-dimensional confined Bose gas. In particular, we consider coherently coupled spin st…
Cavity-Mediated Collective Resonant Suppression of Local Molecular Vibrations
Vasil Rokaj, Ilia Tutunnikov, H. R. Sadeghpour
Recent advances in polaritonic chemistry suggest that chemical reactions can be controlled via collective vibrational strong coupling (VSC) in a cavity. In this fully analytical wo…
Tunable pairing with local spin-dependent Rydberg molecule potentials in an atomic Fermi superfluid
Chih-Chun Chien, Seth T. Rittenhouse, S. I. Mistakidis +1
We explore the energy spectrum and eigenstates of two-component atomic Fermi superfluids with tunable pairing interactions in the presence of spin-dependent ultra long-range Rydber…
Dynamical generation and transfer of nonclassical states in strongly interacting light-matter systems in cavities
Ilia Tutunnikov, Vasil Rokaj, Jianshu Cao +1
We propose leveraging strong and ultrastrong light-matter coupling to efficiently generate and exchange nonclassical light and quantum matter states. Two initial conditions are con…
