Mapping polariton Bose–Einstein condensate onto vibrational degrees of freedom

Posted by dbos Berkeley

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 molecular exciton-polariton systems, where nonequilibrium polariton Bose–Einstein condensation coexists with macroscopically occupied vibrational states. Strong vibronic coupling in molecules induces an effective optomechanical interaction between […]

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

Posted by klaurent Berkeley

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 […]
