Topological Excitations of Hidden Order in URu$_2$Si$_2$ Under Extreme Electric Fields

Kavli Affiliate: Brad Ramshaw | First 5 Authors: Laurel E Winter, Arkady Shekhter, Brad Ramshaw, Ryan E. Baumbach, Eric D. Bauer | Summary: Quantum materials are epitomized by the influence of collective modes upon their macroscopic properties. Relatively few examples exist, however, whereby coherence of the ground-state wavefunction directly contributes to the conductivity. Notable examples […]

Optomechanical damping as the origin of sideband asymmetry

Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, Ya. M. Blanter, , , | Summary: Sideband asymmetry in cavity optomechanics has been explained by particle creation and annihilation processes, which bestow an amplitude proportional to ‘n+1’ and ‘n’ excitations to each of the respective sidebands. We discuss the issues with […]

Evidence for a Spatially-Modulated Superfluid Phase of $^3$He under Confinement

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Lev V. Levitin, Ben Yager, Laura Sumner, Brian Cowan, Andrew J. Casey | Summary: In superfluid $^3$He-B confined in a slab geometry, domain walls between regions of different order parameter orientation are predicted to be energetically stable. Formation of the spatially-modulated superfluid stripe phase has been […]

A 1.6:1 Bandwidth Two-Layer Antireflection Structure for Silicon Matched to the 190-310 GHz Atmospheric Window

Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Fabien Defrance, Cecile Jung-Kubiak, Jack Sayers, Jake Connors, Clare deYoung | Summary: Although high-resistivity, low-loss silicon is an excellent material for THz transmission optics, its high refractive index necessitates antireflection treatment. We fabricated a wide-bandwidth, two-layer antireflection treatment by cutting subwavelength structures into the silicon surface […]

Yield precursor dislocation avalanches in small crystals: the irreversibility transition

Kavli Affiliate: Julia R. Greer | First 5 Authors: Xiaoyue Ni, Haolu Zhang, Danilo B. Liarte, Louis W. McFaul, Karin A. Dahmen | Summary: The transition from elastic to plastic deformation in crystalline metals shares history dependence and scale-invariant avalanche signature with other non-equilibrium systems under external loading: dilute colloidal suspensions, plastically-deformed amorphous solids, granular […]

Compressive Light Field Reconstructions using Deep Learning

Kavli Affiliate: Alyosha Molnar | First 5 Authors: Mayank Gupta, Arjun Jauhari, Kuldeep Kulkarni, Suren Jayasuriya, Alyosha Molnar | Summary: Light field imaging is limited in its computational processing demands of high sampling for both spatial and angular dimensions. Single-shot light field cameras sacrifice spatial resolution to sample angular viewpoints, typically by multiplexing incoming rays […]

Computation of a Theoretical Membrane Phase Diagram, and the Role of Phase in Lipid Raft-Mediated Protein Organization

Kavli Affiliate: Barbara Baird | First 5 Authors: Eshan D. Mitra, Samuel C. Whitehead, David Holowka, Barbara Baird, James P. Sethna | Summary: Lipid phase heterogeneity in the plasma membrane is thought to be crucial for many aspects of cell signaling, but the physical basis of participating membrane domains such as "lipid rafts" remains controversial.
