Improved Transition Oscillator Probabilities for Laser Transitions in Xe I

October 12, 2021
Author(s)
Abhijit Dasgupta, J P. Apruzes, O Zatsarinny, K Bartschat, Charlotte F. Fischer
The atomic xenon laser is among the most efficient and powerful of thenear-infrared gas lasers, especially when pumped by molecular ions in an Ar-Xemixture. Accurate oscillator strengths for the laser transitions are criticaltodeveloping a fundamental

Freezing of a Disorder Induced Spin Liquid with Strong Quantum Fluctuations

June 29, 2021
Author(s)
Xiao Hu, Daniel M. Pajerowski, Depei Zhang, Andrey Podlesnyak, Yiming Qiu, Qing Huang, Haidong Zhou, Israel Klich, Alexander I. Kolesnikov, M. B. Stone, Seung-Hun Lee
Sr 2CuTe 0.5W 0.5O 6 is a square-lattice magnet with super-exchange between S = 1/2 Cu 2+ spins mediated by randomly distributed Te and W ions. Here, using sub-K temperature and 20 µeV energy resolution neutron scattering experiments we show that this

Effective Spin-1/2 Scalar Chiral Order on Kagome Lattices in Nd 3 Sb 3 Mg 2 O 14

May 20, 2016
Author(s)
A. Scheie, M. Sanders, J. Krizan, Yiming Qiu, R. J. Cava, Collin L. Broholm
We introduce Nd 3Sb 3Mg 2O 14 with ideal kagome lattices of neodymium ions in ABC stacking. Thermodynamic measurements show a Curie-Weiss temperature of θ cw = -0.12 Jm a Bd 3+ spin 1/2 Kramers doublet ground state, and as second order phase transition at

Magnetic Neutron Scattering

October 2, 2012
Author(s)
Jeffrey W. Lynn
Neutron scattering is a powerful tool to investigate the magnetic structures and spin dynamics of materials. In this tutorial we provide examples of the application of magnetic neutron diffraction using polycrystalline materials, single crystals, thin

Toward Heisenberg-Limited Spectroscopy with Multiparticle Entangled States

January 1, 2004
Author(s)
Dietrich G. Leibfried, Murray D. Barrett, T Schaetz, Joseph W. Britton, J Chiaverini, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
The precision in spectroscopy of any quantum system is fundamentally limited by the Heisenberg uncertainty relation for energy and time. For N systems, this limit requires that they be in a quantum-mechanically entangled state. We describe a scalable

X-Ray Anomalous Scattering Study of a Charge-Ordered State in NaV 2 O 3

November 13, 2000
Author(s)
Shin-ichi Nakao, K Ohwada, N Takesue, Y Fujiii, M Isobe, Y Ueda, M V. Zimmermann, J P. Hill, D Gibbs, Joseph Woicik, L Koyama, Y Murakami
Charge ordering of V 4+ and V 5+ in NaV 2O 5 has been studied by an X-ray diffraction technique using anomalous scattering near a vanadium K-aborption edge to critically enhance a contrast between the two ions. A dramatic energy dependence of the

Electromagnetically induced transparency in inhomogeneously broadened solid media

May 15, 2019
Author(s)
Kumel H. Kagalwala, Fan Haoquan, Sergey Polyakov, Alan L. Migdall, Elizabeth A. Goldschmidt
We study, theoretically and experimentally, electromagnetically induced transparency (EIT) in two di erent solid-state systems. Unlike many implementations in homogeneously broadened media, these systems exhibit inhomogeneous broadening of their optical
