Beat note stabilization of mode-locked lasers for quantum information processing
R. Islam, W. C. Campbell, T. Choi +18
We stabilize a chosen radiofrequency beat note between two optical fields derived from the same mode-locked laser pulse train, in order to coherently manipulate quantum information…
Non-analytic behavior of the Casimir force across a Lifshitz transition in a spin-orbit coupled material
Andrew A. Allocca, Justin H. Wilson, Victor Galitski
We propose the Casimir effect as a general method to observe Lifshitz transitions in electron systems. The concept is demonstrated with a planar spin-orbit coupled semiconductor in…
Commissioning of the Francium Trapping Facility at TRIUMF
M. Tandecki, J. Zhang, R. Collister +6
We report on the successful commissioning of the Francium Trapping Facility at TRIUMF. Large laser-cooled samples of francium are produced from a francium ion beam delivered by the…
Spin-orbit coupling in quantum gases
Victor Galitski, Ian B. Spielman
Spin-orbit coupling links a particle's velocity to its quantum mechanical spin, and is essential in numerous condensed matter phenomena, including topological insulators and Majora…
Threshold for creating excitations in a stirred superfluid ring
K. C. Wright, R. B. Blakestad, C. J. Lobb +2
We have measured the threshold for creating long-lived excitations when a toroidal Bose-Einstein condensate is stirred by a rotating (optical) barrier of variable height. When the…
Hong-Ou-Mandel atom interferometry in tunnel-coupled optical tweezers
A. M. Kaufman, B. J. Lester, C. M. Reynolds +5
The quantum statistics of atoms is typically observed in the behavior of an ensemble via macroscopic observables. However, quantum statistics modifies the behavior of even two part…
Cyclotron dynamics of interacting bosons in artificial magnetic fields
Xiaopeng Li, S. Das Sarma
We study theoretically quantum dynamics of interacting bosons in artificial magnetic fields as engineered in recent ultracold atomic experiments, where quantum cyclotron orbital mo…
Theory of dynamic nuclear polarization and feedback in quantum dots
Sophia E. Economou, Edwin Barnes
An electron confined in a quantum dot interacts with its local nuclear spin environment through the hyperfine contact interaction. This interaction combined with external control a…
Landau-Zener population control and dipole measurement of a two level system bath
M. S. Khalil, S. Gladchenko, M. J. A. Stoutimore +3
Tunneling two level systems (TLS), present in dielectrics at low temperatures, have been recently studied for fundamental understanding and superconducting device development. Acco…
Superconducting pairing in the spin-density-wave phase of iron pnictides
Jacob Schmiedt, P. M. R. Brydon, Carsten Timm
Some of the iron pnictides show coexisting superconductivity and spin-density-wave order. We study the superconducting pairing instability in the spin-density-wave phase. Assuming…
Spiral antiferromagnets beyond the spin-wave approximation: frustrated and Heisenberg models in the honeycomb lattice
Andrea Di Ciolo, Juan Carrasquilla, Federico Becca +2
We examine the stability of classical states with a generic incommensurate spiral order against quantum fluctuations. Specifically, we focus on the frustrated spin-1/2 and Hei…
Robust quantum gates for singlet-triplet spin qubits using composite pulses
Xin Wang, Lev S. Bishop, Edwin Barnes +2
We present a comprehensive theoretical treatment of SUPCODE, a method for generating dynamically corrected quantum gate operations, which are immune to random noise in the environm…
Quantum many-body models with cold atoms coupled to photonic crystals
J. S. Douglas, H. Habibian, C. -L. Hung +3
Using cold atoms to simulate strongly interacting quantum systems represents an exciting frontier of physics. However, as atoms are nominally neutral point particles, this limits t…

We present composite pulse sequences that perform fault-tolerant two-qubit gate operations on exchange-only quantum dot spin qubits in various experimentally relevant geometries. W…
Beyond the Spin Model Approximation for Ramsey Spectroscopy
A. P. Koller, M. Beverland, A. V. Gorshkov +1
Ramsey spectroscopy has become a powerful technique for probing non-equilibrium dynamics of internal (pseudospin) degrees of freedom of interacting systems. In many theoretical tre…

Ryan M. Wilson, Brandon M. Peden, Charles W. Clark +1
We consider an oblate Bose-Einstein condensate of heteronuclear polar molecules in a weak applied electric field. This system supports a rich quasiparticle spectrum that plays a cr…
A noise inequality for classical forces
Dvir Kafri, J. M. Taylor
Lorentz invariance requires local interactions, with force laws such as the Coulomb interaction arising via virtual exchange of force carriers such as photons. Many have considered…
