Sympathetic Mechanism for Vibrational Condensation Enabled by Polariton Optomechanical Interaction

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Vladislav Yu. Shishkov, Evgeny S. Andrianov, Sergei Tretiak, K. Birgitta Whaley, Anton V. Zasedatelev | Summary: We demonstrate a macro-coherent regime in exciton-polariton systems, where nonequilibrium polariton Bose–Einstein condensation coexists with macroscopically occupied vibrational states. Strong exciton-vibration coupling induces an effective optomechanical interaction between cavity polaritons and […]

All-dielectric high-Q dynamically tunable transmissive metasurfaces

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Ruzan Sokhoyan, Claudio U. Hail, Morgan Foley, Meir Y. Grajower, Harry A. Atwater | Summary: Active metasurfaces, which are arrays of actively tunable resonant elements, can dynamically control the wavefront of the scattered light at a subwavelength scale. To date, most active metasurfaces that enable dynamic […]

Real Effect or Bias? Best Practices for Evaluating the Robustness of Real-World Evidence through Quantitative Sensitivity Analysis for Unmeasured Confounding

Kavli Affiliate: Xiang Zhang | First 5 Authors: Douglas Faries, Chenyin Gao, Xiang Zhang, Chad Hazlett, James Stamey | Summary: The assumption of no unmeasured confounders is a critical but unverifiable assumption required for causal inference yet quantitative sensitivity analyses to assess robustness of real-world evidence remains underutilized. The lack of use is likely in […]

In operando cryo-STEM of pulse-induced charge density wave switching in TaS$_2$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: James L Hart, Saif Siddique, Noah Schnitzer, Stephen D. Funni, Lena F. Kourkoutis | Summary: The charge density wave (CDW) material 1T-TaS$_2$ exhibits a pulse-induced insulator-to-metal transition, which shows promise for next-generation electronics such as memristive memory and neuromorphic hardware. However, the rational design of TaS$_2$ […]

Fully scalable randomized benchmarking without motion reversal

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Jordan Hines, Daniel Hothem, Robin Blume-Kohout, Birgitta Whaley, Timothy Proctor | Summary: We introduce binary randomized benchmarking (BiRB), a protocol that streamlines traditional RB by using circuits consisting almost entirely of i.i.d. layers of gates. BiRB reliably and efficiently extracts the average error rate of a Clifford […]

Approximate Lie symmetries and singular perturbation theory

Kavli Affiliate: L. Mahadevan | First 5 Authors: Alexander J. Dear, L. Mahadevan, , , | Summary: Perturbation theory plays a central role in the approximate solution of nonlinear differential equations. The resultant series expansions are usually divergent and require treatment by singular perturbation methods to generate uniformly valid solutions. However, applying these methods is […]
