Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

April 13, 2022
Author(s)
Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal

Electrically Driven Exchange Bias via Solid State Magneto-Ionics

April 13, 2022
Author(s)
Peyton Murray, , , , , Alexander Grutter, Brian Kirby,
Electrically induced ionic motion offers a new way to realize voltage-controlled magnetism, opening the door to a new generation of logic, sensor, and data storage technologies. Here, we demonstrate an effective approach to magneto-ionically and

Author(s)
Nina Andrejevic, Zhantao Chen, Thanh Nguyen, Leon Fan, Henry Heiberger, Valeria Lauter, Ling-Jie Zhou, Yi-Fan Zhao, Cui-Zu Chang, Alexander Grutter, Mingda Li
Polarized neutron reflectometry (PNR) is a powerful technique to interrogate the structures of multilayered magnetic materials with depth sensitivity and nanometer resolution. However, reflectometry profiles often inhabit a complicated objective function

Evolution of Magnetic Interactions in Sb-Substituted MnBi 2 Te 4

Author(s)
S. Riberolles, Q. Zhang, Elijah Gordon, Nicholas Butch, Liqin Ke, J.-Q. Yan, R. McQueeney
The Mn(Bi1−xSbx)2Te4 series is purported to span from antiferromagnetic (AF) topological insulator at x = 0 to a trivial AF insulator at x = 1. Here we report on neutron diffraction and inelastic neutron scattering studies of the magnetic interactions

Interplay between Magnetism and Superconductivity in UTe 2

April 13, 2022
Author(s)
Di Wei, David Saykin, Oliver Miller, Sheng Ran, Shanta Saha, Daniel Agterberg, Jorg Schmalian, Nicholas Butch, Johnpierre N. Paglione, Aharon Kapitulnik
Time-reversal symmetry breaking (TRSB) in UTe2 was inferred from observations of a spontaneous Kerr response in the superconducting state after cooling in zero magnetic field, while a finite c-axis magnetic field training was further used to determine the

Inverse-designed multi-dimensional silicon photonic transmitters

April 13, 2022
Author(s)
Travis Briles, Jordan Stone, Scott Papp
Modern microelectronic processors have migrated towards parallel computing architectures with many-core processors. However, such expansion comes with diminishing returns exacted by the high cost of data movement between individual processors. The use of

Late Stage Domain Coarsening Dynamics of Lamellar Block Copolymers

April 13, 2022
Author(s)
Jack F. Douglas, Maninderjeet Singh, Wenjie Wu, Vinay Nuka, Joseph Strzalka, Alamgir Karim
Block copolymer (BCP) phase separation is an intriguing phenomenon whose dynamics can be expected to differ significantly from that of the polymer blends due to constraint of chain connectivity that limits the ultimate scale of phase separation and the

Measurement of mass of aerosol particles

Author(s)
Kevin J. Coakley, Robert Hagwood, Kensei Ehara, Nobuhiko FUKUSHIMA, Kittichote WORACHOTEKAMJORN, Naoko TAJIMA, Hiromu SAKURAI
An aerosol particle mass analyzer (APM) which classifies aerosol particles according to their mass has been developed. Mass distributions of aerosol particles can be measured by the APM combined with a particle counting device. Particle mass that can be

Author(s)
Drew S. Tack, Peter Tonner, Abe Pressman, Nathanael David Olson, Eugenia Romantseva, Nina Alperovich, Olga Vasilyeva, David J. Ross, Sasha F. Levy
Allostery is a fundamental biophysical mechanism where the activity of a biomolecule is regulated by the binding of a ligand. Despite playing a central role in many biological processes, a quantitative understanding of allostery is lacking. To

The case for a U(1) p Quantum Spin Liquid Ground State in the Dipole-Octupole Pyrochlore Ce 2 Zr 2 O 7

April 13, 2022
