Kavli Affiliate: Menno Veldhorst | First 5 Authors: Xiao Xue, Bishnu Patra, Jeroen P. G. van Dijk, Nodar Samkharadze, Sushil Subramanian | Summary: The most promising quantum algorithms require quantum processors hosting millions of quantum bits when targeting practical applications. A major challenge towards large-scale quantum computation is the interconnect complexity. In current solid-state qubit […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing, Yang Cui, Naseem Ud Din | Summary: Direct measurements of photoexcited carrier dynamics in nickel are made using few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy at the nickel M$_{2,3}$ edge. It is observed that the core-level absorption lineshape of […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Peng Zhang, Christian Kern, Sijie Sun, David A. Weitz, Pai Wang | Summary: We demonstrate a new class of elastic waves in the bulk: When longitudinal and transverse components propagate at the same speed, rolling waves with a spin that is not parallel to the wave […]
Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, A. Nick Vamivakas | Summary: We present a many-body theory for exciton-trion-polaritons in doped two-dimensional materials. Exciton-trion-polaritons are robust coherent hybrid excitations involving excitons, trions, and photons. Signatures of these polaritons have been recently seen in experiments. In these […]
Kavli Affiliate: James Bock | First 5 Authors: Lionel Duband, Thomas Prouve, James Bock, Lorenzo Moncelsi, Alessandro Schillaci | Summary: In the field of astrophysics, the faint signal from distant galaxies and other dim cosmological sources at millimeter and submillimeter wavelengths require the use of high-sensitivity experiments. Cryogenics and the use of low-temperature detectors are […]
Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Sebastian Fürthauer, Daniel J Needleman, Michael J. Shelley, , | Summary: Living matter moves, deforms, and organizes itself. In cells this is made possible by networks of polymer filaments and crosslinking molecules that connect filaments to each other and that act as motors to do mechanical […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Warren Jin, Qi-Fan Yang, Lin Chang, Boqiang Shen, Heming Wang | Summary: Driven by narrow-linewidth bench-top lasers, coherent optical systems spanning optical communications, metrology and sensing provide unrivalled performance. To transfer these capabilities from the laboratory to the real world, a key missing ingredient is a […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Wei Ruan, Yi Chen, Shujie Tang, Jinwoong Hwang, Hsin-Zon Tsai | Summary: Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state whose low-energy behavior is described by a spinon Fermi surface. Directly imaging the resulting spinons, however, is difficult […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Hengjiang Ren, Tirth Shah, Hannes Pfeifer, Christian Brendel, Vittorio Peano | Summary: Recent advances in cavity-optomechanics have now made it possible to use light not just as a passive measuring device of mechanical motion, but also to manipulate the motion of mechanical objects down to the level […]
Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, Christina Manolatou | Summary: Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged excitons), but both peaks have been recently attributed to superpositions […]
