Chirality density wave of the ‘hidden order’ phase in URu2Si2

Authors: H.-H. Kung, R. E. Baumbach, E. D. Bauer, V. K. Thorsmølle, W.-L. Zhang, K. Haule, J. A. Mydosh, G. Blumberg Abstract: A second-order phase transition in a physical system is associated with the emergence of an “order parameter” and a spontaneous symmetry breaking. The heavy fermion superconductor URu2Si2 has a “hidden order” (HO) phase below …

Compact nanomechanical plasmonic phase modulators

Authors: B. S. Dennis, M. I. Haftel, D. A. Czaplewski, D. Lopez, G. Blumberg and V. A. Aksyuk Abstract: Highly confined optical energy in plasmonic devices is advancing miniaturization in photonics. However, for mode sizes approaching ≈10 nm, the energy increasingly shifts into the metal, raising losses and hindering active phase modulation. Here, we propose a …
