High resolution adaptive imaging of a single atom
J. D. Wong-Campos, K. G. Johnson, B. Neyenhuis +2
We report the optical imaging of a single atom with nanometer resolution using an adaptive optical alignment technique that is applicable to general optical microscopy. By decompos…
Photoassociation of spin polarized Chromium
Jahn Rührig, Tobias Bäuerle, Paul S. Julienne +2
We report the homonuclear photoassociation (PA) of ultracold atoms in an optical dipole trap. This constitutes the first measurement of PA in an element with t…
Emergent Weyl excitations in systems of polar particles
Sergey V. Syzranov, Michael L. Wall, Bihui Zhu +2
Weyl fermions are massless chiral particles first predicted in 1929 and once thought to describe neutrinos. Although never observed as elementary particles, quasiparticles with Wey…
Non-Markovian quantum friction of bright solitons in superfluids
Dmitry K. Efimkin, Johannes Hofmann, Victor Galitski
We explore the quantum dynamics of a bright matter-wave soliton in a quasi-one-dimensional bosonic superfluid with attractive interactions. Specifically, we focus on the dissipativ…
Robust Zero Energy Bound States Localized at Magnetic Impurities in Iron-based Superconductors
Kangjun Seo, Jay D. Sau, Sumanta Tewari
We investigate the effect of spin-orbit coupling on the in-gap bound states localized at magnetic impurities in multi-band superconductors with unconventional (sign-changed) and co…
Sisyphus Thermalization of Photons in a Cavity-Coupled Double Quantum Dot
M. J. Gullans, J. Stehlik, Y. -Y. Liu +3
We investigate the non-classical states of light that emerge in a microwave resonator coupled to a periodically-driven electron in a nanowire double quantum dot (DQD). Under certai…
Understanding analog quantum simulation dynamics in coupled ion-trap qubits
Yang-Le Wu, S. Das Sarma
We study numerically a disordered transverse-field Ising Hamiltonian with long-range couplings. This model was recently investigated experimentally in a trapped-ion quantum simulat…
Rashba realization: Raman with RF
Daniel L. Campbell, Ian B. Spielman
We theoretically explore a Rashba spin-orbit coupling scheme which operates entirely in the absolute ground state manifold of an alkali atom, thereby minimizing all inelastic proce…
Doublon dynamics and polar molecule production in an optical lattice
Jacob P. Covey, Steven A. Moses, Martin Garttner +8
Ultracold polar molecules provide an excellent platform to study quantum many-body spin dynamics, which has become accessible in the recently realized low entropy quantum gas of po…
Filter function formalism beyond pure dephasing and non-Markovian noise in singlet-triplet qubits
Edwin Barnes, Mark S. Rudner, Frederico Martins +3
The filter function formalism quantitatively describes the dephasing of a qubit by a bath that causes Gaussian fluctuations in the qubit energies with an arbitrary noise power spec…
Noise suppression using symmetric exchange gates in spin qubits
Frederico Martins, Filip K. Malinowski, Peter D. Nissen +6
We demonstrate a substantial improvement in the spin-exchange gate using symmetric control instead of conventional detuning in GaAs spin qubits, up to a factor-of-six increase in t…
Quantum phases of interacting electrons in three-dimensional dirty Dirac semimetals
Bitan Roy, Sankar Das Sarma
We theoretically study the stability of three dimensional Dirac semimetals against short-range electron-electron interaction and quenched time-reversal symmetric disorder (but excl…
Two-photon interference from a bright single photon source at telecom wavelengths
Je-Hyung Kim, Tao Cai, Christopher J. K. Richardson +2
Long-distance quantum communication relies on the ability to efficiently generate and prepare single photons at telecom wavelengths. In many applications these photons must also be…
A strong loophole-free test of local realism
Lynden K. Shalm, Evan Meyer-Scott, Bradley G. Christensen +31
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parti…

Neal Solmeyer, Xiao Li, Qudsia Quraishi
We present a simplified version of a repeater protocol in a cold neutral-atom ensemble with Rydberg excitations optimized for two-node entanglement generation and describe a protoc…
Nonlinear microwave photon-occupancy of a driven resonator strongly coupled to a transmon qubit
Baladitya Suri, Zach Keane, Lev S. Bishop +3
We measure photon-occupancy in a thin-film superconducting lumped element resonator coupled to a transmon qubit at 20mK and find a nonlinear dependence on the applied microwave…
A development of the CI + all-order method and application to the parity-nonconserving amplitude and other properties of Pb
S. G. Porsev, M. G. Kozlov, M. S. Safronova +1
We have further developed and extended a method for calculation of atomic properties based on a combination of the configuration interaction and coupled-cluster approach. We have a…
Microwave photon-assisted phase-incoherent Cooper-pair tunneling in a Josephson STM

We have observed photon-assisted Cooper-pair tunneling in an atomic-scale Josephson junction formed between a superconducting Nb tip and a superconducting Nb sample in a scanning t…
Exact calculation of phonon effects on spin squeezing
D. Dylewsky, J. K. Freericks, M. L. Wall +2
Theoretical models of spins coupled to bosons provide a simple setting for studying a broad range of important phenomena in many-body physics, from virtually mediated interactions…
Resonant wavepackets and shock waves in an atomtronic SQUID
Yi-Hsieh Wang, A. Kumar, F. Jendrzejewski +5
The fundamental dynamics of ultracold atomtronic devices are reflected in their phonon modes of excitation. We probe such a spectrum by applying a harmonically driven potential bar…
