Finding Bugs in Cryptographic Hash Function Implementations

Author(s)
Nicky W. Mouha, Mohammad Raunak, David R. Kuhn, Raghu N. Kacker
Cryptographic hash function implementations can be particularly difficult to test, and bugs can remain unnoticed for a very long time. We revisit the NIST SHA-3

Superconducting optoelectronic networks III: synaptic plasticity

Author(s)
Jeffrey M. Shainline, Adam N. McCaughan, Sonia M. Buckley, Christine A. Donnelly, Manuel C. Castellanos Beltran, Michael L. Schneider, Richard P. Mirin, Sae Woo Nam
As a means of dynamically reconfiguring the synaptic weight of a superconducting optoelectronic loop neuron, a superconducting flux storage loop is inductively

Universal Geometric Frustration in Pyrochlores

Benjamin A Trump, Syed M. Koohpayeh, Ken J. T. Livi, JiaJia Wen, Kathyrn Arpino, Quentin M. Ramasse, Rik Brydson, Mikhail Feygenson, H. Takeda, M. Takigawa, K. Kimura, S. Nakatsuji, Collin L. Broholm, T. M. McQueen
We report on the structural details of Pr 2Zr 2O 6O', La 2Zr 2O 6O', and Yb 2Ti 2O 6O' in the A 2B 2O 6O' pyrochlore structure. X-ray and neutron powder

Local Quantum Phase Transition in YFe2Al^d10

Author(s)
W. J. Gannon, L. S. Wu, I. A. Zaliznyak, W. H. Xu, A. M. Tsvelik, Yiming Qiu, Jose Rodriguez Rivera, M. C. Aronson
A phase transition occurs when correlated regions of a new phase grow to span the system and the fluctuations within the correlated regions become long-lived

Spin-Phonon Couplings in Transition Metal Complexes with Slow Magnetic Relaxation

Author(s)
Duncan H. Moseley, Shelby E. Stavretis, Komalavalli Thirunavukkuarasu, Mykhaylo Ozerov, Yongqiang Cheng, Luke L. Daemen, Jonathan Ludwig, Zhengguang Lu, Dmitry Smirnov, Craig Brown, Anup Pandey, A. J. Ramirez-Cuesta, Adam C. Lamb, Mihail Atanasov, Eckhard Bill, Frank Neese, Zi-Ling Xue
Co(acac) 2(H 2O) 2 (1, acac = acetylacetonate), a model transition metal complex, displays field-induced slow magnetic relaxation as a single-molecule magnet

Residual Stress in Additive Manufactured Nickel Alloy 625 Parts

Author(s)
Lindsey B. Bass, Justin L Milner, Thomas Gnaupel-Herold, Shawn P. Moylan
One of the key barriers to widespread adoption of additive manufacturing (AM) for metal parts is the build-up of residual stresses. In the laser-based powder

Perpetual emulation threshold of PT-symmetric Hamiltonians

Author(s)
Ian B. Spielman, Clive Emary, Dimitris Trypogeorgos, Ana Vald?s-Curiel
We describe a technique to emulate a two-level PT-symmetric spin Hamiltonian, replete with gain and loss, using only the unitary dynamics of a larger quantum

A practical field guide to thermoelectrics: fundamentals, synthesis, and characterization

Author(s)
Alex Zevalkink, David M. Smiadak, Joshua Martin, Michael Chabinyc, Olivier Delaire, Jeffrey Blackburn, Andrew Ferguson, Jian Wang, Kirill Kovnir, Laura Schelhas, Stephen D. Kang, Maxwell T. Dylla, G. J. Snyder, Brenden Ortiz, Eric Toberer
The study of thermoelectric materials spans condensed matter physics, materials science and engineering, and solid-state chemistry. The diversity of the
