Numerical methods every atomic and molecular theorist should know

December 16, 2019
Author(s)
Barry I. Schneider, Heman Gharibnejad
This review article discusses a few theoretical and numerical approaches that have been successfully used to treat electron scattering and photoionization of atoms and molecules and the interaction of those systems with intense, short-pulse electromagnetic

Spectrum of Ni V in the Vacuum Ultraviolet

November 27, 2019
Author(s)
Jacob W. Ward, A J. Raassen, Alexander Kramida, Gillian Nave
This work presents 97 remeasured Fe V wavelengths (1200 Å to 1600 Å) and 123 remeasured Ni V wavelengths (1200 Å to 1400 Å) with uncertainties of approximately 2 mÅ. An additional 67 remeasured Fe V wavelengths and 72 remeasured Ni V wavelengths with

Quantum interference between photons from an atomic ensemble and a remote atomic ion

A. Craddock, J. Hannegan, D. Ornelas-Huerta, J. Siverns, A. Hachtel, E. Goldschmidt, James V. Porto, Q. Quraishi, S. Rolston
Many remote-entanglement protocols rely on the generation and interference of photons produced by nodes within a quantum network. Quantum networks based on heterogeneous nodes provide a versatile platform by utilizing the complimentary strengths of the

Advanced technologies for quantum photonic devices based on epitaxial quantum dots

October 11, 2019
Author(s)
Tian M. Zhao, Yan Chen, Yu Ying, Li Qing, Marcelo I. Davanco, Jin Liu
Photonic quantum technology is creating breakthroughs in both fundamental quantum science and applications such as quantum communication, computation and sensing. Regarded as artificial atoms due to the discrete energy levels they support, semiconductor

Study of the neutron spin-orbit interaction in silicon

September 29, 2019
Author(s)
Thomas R. Gentile, Michael G. Huber, Muhammad D. Arif, Daniel Hussey, David Jacobson, Donald D. Koetke, Murray Peshkin, Thomas Dombeck, Paul Nord, Dimitry A. Pushin, Robert Smither
The neutron spin-orbit interaction, which results from the interaction of a moving neutron's magnetic dipole moment (MDM) with the atomic electric fields, induces a small rotation of the neutron's spin in one Bragg reflection. In our experiment neutrons

Exceeding the Sauter-Schwinger limit of pair production with a quantum gas

September 21, 2019

Alina M. Pineiro Escalera, Mingwu Lu, Dina Genkina, Ian Spielman
We quantum-simulated particle-antiparticle pair production with a bosonic quantum gas in an optical lattice by emulating the requisite 1d Dirac equation and uniform electric field. We emulated field strengths far in excess of Sauter-Schwinger's limit for

Indistinguishable photons from deterministically integrated single quantum dots in heterogeneous GaAs/Si3N4 quantum photonic circuits

September 15, 2019
Author(s)
Peter Schnauber, Anshuman Singh, Johannes Schall, Suk I. Park, Jin Dong Song, Sven Rodt, Kartik Srinivasan, Stephan Reitzenstein, Marcelo I. Davanco
With in-situ electron beam lithography we deterministically integrate single InAs quantum dots into heterogeneous GaAs/Si3N4 waveguide circuits. Through microphotoluminescence spectroscopy, we show on-chip quantum dot emission of single, postselected
