Thomas Halloran, Felix Desrochers, Emily Zhang, Tong Chen, Li E. Chern, Zhijun Xu, Barry Winn, Melissa Graves-Brook, M. B. Stone, Alexander I. Kolesnikov, Yiming Qiu, Ruidan Zhong, Robert Cava, Yong Kim, Collin L. Broholm
Recently, Co-based honeycomb magnets have been proposed as promising candidate materials to host the Kitaev spin liquid state. One of the front-runners is BaCo 2(AsO 4) 2 (BCAO), where it was suggested that the exchange processes between Co 2+ ions via the

Peng Chen, Qi Yao, Junqi Xu, Qiang Sun, Alexander Grutter, Patrick Quarterman, Purnima P. Balakrishnan, Christy J. Kinane, Andrew J. Caruana, Sean Langridge, Ang Li, Barat Achinuq, Emily Heppell, Yuchen Ji, Shanshan Liu, Baoshan Cui, Jiuming Liu, Puyang Huang, Zhongkai Liu, Guoqiang Yu, Faxian Xiu, Thorsten Hesjedal, Jin Zou, Xiaodong Han, Haijun Zhang, Yumeng Yang, Xufeng Kou
The intrinsic magnetic topological insulator MnBi 2Te 4 (MBT) has provided a platform for the successful realization of exotic quantum phenomena. To broaden the horizons of MBT-based material systems, we intercalate ferromagnetic MnTe layers to construct

Symmetry-dependent ultrafast manipulation of nanoscale magnetic domains

Nanna Hagstrom, Rahul Jangid, F. N. U. Meera, Diego Turenne, Jeffrey Brock, Erik Lamb, Boyan Stoychev, Justine Schlappa, Natalia Gerasimova, Benjamin Van Kuiken, Rafael Gort, Laurent Mercadier, Loic Le Guyader, Andrey Samartsev, Andreas Scherz, Giuseppe Mercurio, Hermann Durr, Alexander Reid, Monika Arora, Hans Nembach, Justin Shaw, Emmanuelle Jal, Eric Fullerton, Mark Keller, Roopali Kukreja, Stefano Bonetti, Thomas J. Silva, Ezio Iacocca
Symmetry is a powerful concept in physics, but its applicability to far-from-equilibrium states is still being understood. Recent attention has focused on how far-from-equilibrium states lead to spontaneous symmetry breaking. Conversely, ultrafast optical

Room-temperature valence transition in a strain-tuned perovskite oxide

Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau, William M. Postiglione, John E. Dewey, Patrick Quarterman, Purnima P. Balakrishnan, Brian Kirby, Hua Zhou, Huikui Cheng, Amanda Huon, Timothy Charlton, Michael R. Fitzsimmons, Caroline Korostynski, Andrew Jacobson, Lucca Figari, Javier Garcia Barriocanal, T. Birol, K. A. Mkhoyan, Chris Leighton
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very different situation was recently uncovered in praseodymium-containing cobalt

A Macroscopic Mass From Quantum Behavior In An Integrated Approach

December 10, 2022
Author(s)
Frank Seifert, Alireza Panna, Lorenz Keck, Leon Chao, Shamith Payagala, Dean G. Jarrett, Dipanjan Saha, Randolph Elmquist, Stephan Schlamminger, Albert Rigosi, David B. Newell, Darine El Haddad
The revision of the International System of Units (SI) on May 20th, 2019, has enabled new improved experiments to consolidate and simplify electrical and mechanical metrology currently underway. Historically within the SI, the definition of energy was only

Constructing quantum many-body scar Hamiltonians from Floquet automata

November 22, 2022
Author(s)
Michael Gullans, Pierre-Gabriel Rozon, Kartiek Agarwal
We provide a systematic approach for constructing approximate quantum many-body scars (QMBS) starting from two-layer Floquet automaton circuits that exhibit trivial many-body re- vivals. We do so by applying successively more restrictions that force local

Nonlinear excitations in ferrites

November 22, 2022
Author(s)
Pavel Kabos
This book chapter describes the processes leading to nonlinear excitations in ferrites at high power levels. We start from equation of motion that include nonlinear terms leading to nonlinear processes. First and second order Suhl instabilities for

Phase-transition-induced Thermal Hysteresis in Type-II Weyl Semimetals MoTe2 and Mo(1-x)W(x)Te2

November 19, 2022
Author(s)
Md Sabbir Akhanda, Sergiy Krylyuk, Diane Dickie, Albert Davydov, Fei Han, Mingda Li, Mona Zebarjadi
The resistivity versus temperature measurement is commonly used for identifying temperature-induced phase change and the resulting hysteresis loop. While the resistance is influenced by both the density of states and the carrier lifetimes, the Seebeck

Frustrated Magnetic Interactions and Quenched Spin Fluctuations in CrAs

The discovery of pressure-induced superconductivity in helimagnets (CrAs, MnP) has attracted significant interest in understanding the relationship between complex magnetism and unconventional superconductivity. However, the nature of the magnetism and

Low power consumption in the static and dynamic modes of operation is a key requirement in the development of modern electronics. Tunnel field-effect transistors with direct band-to-band charge tunnelling and steep-subthreshold-slope transfer

Unravelled and Glassy Magnetism in PbFe 1/2 Nb 1/2 O 3 - (2) Neutron Scattering

We apply neutron scattering to investigate the magnetism in the relaxor ferroelectric PbFe 1/2Nb 1/2O 3 (PFN). Similar to the lack of spatially long-range ferroelectric order in prototypical relaxors like Pb(Mg,Zn) 1/3Nb 2/3O 3 (PMN and PZN), spatially

We describe a method for deriving surface functionalization patterns for colloidal systems that can induce self-assembly into any chosen periodic symmetry at a planar interface. The result is a sequence of letters, s ∈ A,T,C,G}, or a gene, that describes
