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 […]

Quasi-BPS categories for K3 surfaces

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We introduce and begin the study of quasi-BPS categories for K3 surfaces, which are a categorical version of the BPS cohomologies for K3 surfaces. We construct semiorthogonal decompositions of derived categories of coherent sheaves on moduli stacks of semistable […]

Topological K-theory of quasi-BPS categories of symmetric quivers with potential

Posted by dbos Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important […]

Topological K-theory of quasi-BPS categories of symmetric quivers with potential

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous work, we studied quasi-BPS categories (of symmetric quivers with potential, of preprojective algebras, of surfaces) and showed they have properties analogous to those of BPS invariants/ cohomologies. For example, quasi-BPS categories are used to formulate categorical analogues […]

Quasi-BPS categories for symmetric quivers with potential

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We study certain categories associated to symmetric quivers with potential, called quasi-BPS categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands […]

Higher Order Nyquist Zone Sampling with RFSoC Data Converters for Astronomical and High Energy Physics Readout Systems

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao Liu, Zeeshan Ahmed, Shawn W. Henderson, Ryan Herbst, Larry Ruckman | Summary: From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases significantly. With the integrated digital mixers and up and […]

Machine assisted annotation in neuroanatomy

Posted by klaurent UCSD / Salk

Kavli Affiliate: David Kleinfeld | Authors: Kui Qian, David Kleinfeld, Beth Friedman and Yoav Freund | Summary: One routine and necessary, yet time-consuming task in neuroanatomy is the annotation of labeled cells relative to the background. Currently, staining and imaging techniques enable the marking of specific cell groups with fluorescent dyes. Modern high throughput scanning […]

All-dielectric high-Q dynamically tunable transmissive metasurfaces

Posted by klaurent Caltech

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 […]
