Fracture Modes in Brittle Coatings With Large Interlayer Modulus Mismatch

October 16, 2008
Author(s)
Herzl Chai, Brian R. Lawn, S Wuttiphan
Fracture modes in a model glass/polymer coating/substrate system indented with hard spheres are investigated. The large modulus mismatch between the glass and polymer results in distinctive transverse fracture modes in the brittle coating: exaggerated

Asymptotic Properties of Self-Energy Coefficients

April 1, 2003
Author(s)
U Jentschura, E O. LeBigot, Peter J. Mohr, Paul Indelicato, G Soff
We investigate the asymptotic properties of higher-order binding corrections to the one-loop self energy of excited states in atomic hydrogen. We evaluate the historically problematic A 60 coefficient for all P states with principal quantum numbers n {less

Experiments in Dilute Atomic Bose-Einstein Condensation

November 1, 1999
Author(s)
Eric A. Cornell, J R. Ensher, C E. Wieman
Why BEC? - In the month we began writing this paper, fourteen papers on the explicit topic of Bose-Einstein condensation (BEC) in a dilute gas appeared in the pages of Physical Review. Both theoretical and experimental activity in BEC has expanded

Transition Metal Dichalcogenides: Making Atomic-Level Magnetism Tunable with Light at Room Temperature

December 10, 2023
Author(s)
Valery Ortiz Jimenez, Yen Pham, Da Zhou, Mingzu Liu, Florence Ann Nugera, Vijaysankar Kalappattil, Tatiana Eggers, Khang Hoang, Dinh Loc Duong, Mauricio Terrones, Humberto Rodriguez Gutierrez, Manh-Huong Phan
The capacity to manipulate magnetization in 2D dilute magnetic semiconductors (2D-DMSs) using light, specifically in magnetically doped transition metal dichalcogenide (TMD) monolayers (M-doped TX2, where M = V, Fe, and Cr; T = W, Mo; X = S, Se, and Te)

Quantum field theory for the chiral clock transition in one spatial dimension

May 3, 2021
Author(s)
Seth P. Whitsitt, Rhine Samajdar, Subir Sachdev
We describe the quantum phase transition in the N-state chiral clock model in spatial dimension d=1. With couplings chosen to preserve time-reversal and spatial inversion symmetries, such a model, is in the universality class of recent experimental studies

Enhanced transport of spin-orbit coupled Bose gases in disordered potentials

September 17, 2020
Author(s)
Yuchen Yue, Ian Spielman, Carlos S? de Melo
Anderson localization is single particle localization phenomena in disordered media that is accompanied by an absence of diffusion. Spin-orbit coupling (SOC) describes an interaction between a particle's spin and its momentum that directly affects its

Protocol for Light-Shift Compensation in a Continuous-Wave Microcell Atomic Clock

September 8, 2020
Author(s)
Moustafa A. Hafiz, Remy Vicarini, Nicolas Passilly, Claudio Calosso, Vincent N. Maurice, Juniper Pollock, V Yudin, John Kitching, Rodolphe Boudot
Light shifts are known to be an important limitation to the mid- and long-term fractional frequency stability of different types of atomic clocks. In this article, we demonstrate the experimental implementation of an anti-light-shift interrogation protocol

Bromination of marine particulate organic matter through oxidative mechanisms

September 14, 2014
Author(s)
Bruce D. Ravel, Alessandra C. Leri, Kathleen Thornton, Lawrence M. Mayer
Although bromine is considered conservative in seawater, it exhibits a well established correlation with organic carbon in marine sediments. This carbon-bromine association was recently attributed to covalent bonding, with organobromine in sinking

Nanoscale spin wave localization using ferromagnetic resonance force microscopy

February 24, 2012
Author(s)
Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert D. McMichael
We utilize ferromagnetic resonance force microscopy (FMRFM) to generate and detect multiple localized spin wave modes with spatial dimensions less than 100 nm in ferromagnetic thin films. Localized spin waves are a potentially powerful tool for imaging

Architectural Effects on Reaction-Diffusion Kinetics in Molecular Glass Photoresists

April 20, 2010
Author(s)
Vivek M. Prabhu, Shuhui Kang, Christopher L. Soles, Christopher K. Ober, Jing Sha, Jin-Kyun Lee, Peter V. Bonnesen
Understanding acid reaction-diffusion kinetics is crucial for controlling the lithographic performance of chemically amplified photoresists. In this work, we study how the molecular architectures of positive-tone chemically amplified molecular glass

Improving Correlations with Inelastic Loss

June 6, 2008
Author(s)
James V. Porto
Correlations are one of the central features of modern condensed matter physics. They arise in systems where the behavior of any given particle in a system depends strongly on all the other particles. Such correlations are what help distinguish the

Time Synchronization for Electronic Distributed Systems

May 28, 2004
Author(s)
John D. Gale, Ya-Shian Li-Baboud
Synchronization of clocks in electronic distributed systems has become critical in an increasing number of applications. Accurate knowledge of the correct time facilitates error trapping, productivity, security and safety. By knowing the precise sequence

Order/Disorder in Electrodeposited Aluminum-Titanium Alloys

July 1, 2003
Author(s)
Gery R. Stafford, T Tsuda, C L. Hussey
The composition, morphology, and crystallographic microstructure of Al-Ti alloys electrodeposited from two Different chloroaluminate molten salt electrolytes were examined. Alloys containing up to 28% atomic fraction Ti were electrodeposited at 150 oC from
