Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Nicolas Swenson, Jeffrey Moses, , | Summary: We illustrate that a Hermitian nonlinear optical system consisting of hybridized parametric amplification and second harmonic generation mimics non-Hermitian evolution dynamics. Oscillation damping, evolution to a static steady state, and exceptional points arise from the use of second […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Yilun Xu, Gang Huang, Jan Balewski, Ravi Naik, Alexis Morvan | Summary: As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large scale extensibility. To tackle this challenge and keep pace with rapidly evolving […]
Kavli Affiliate: Jeevak Parpia | First 5 Authors: Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev, Abhilash Sebastian, Yefan Tian | Summary: We examine the discontinuous first-order superfluid $^3$He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions: cooling at fixed pressure yields a well defined […]

Kavli Affiliate: Ariel Amir | First 5 Authors: Jiseon Min, Ariel Amir, , , | Summary: Many unicellular organisms allocate their key proteins asymmetrically between the mother and daughter cells, especially in a stressed environment. A recent theoretical model is able to predict when the asymmetry in segregation of key proteins enhances the population fitness, […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Anton R. Akhmerov, Daniel Varjas, , | Summary: Protection of topological surface states by reflection symmetry breaks down when the boundary of the sample is misaligned with one of the high symmetry planes of the crystal. We demonstrate that this limitation is removed in […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Kristin A. Persson | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]

Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Logan Wright, Demetrios Christodoulides | Summary: An equilibrium thermodynamic framework that describes highly-multimode optical processes was introduced recently. This theory predicts the outcomes of complex linear and nonlinear multimode interactions based on thermodynamic principles and provides analytic results for the distributions […]
Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Nicholas Bender, Logan Wright | Summary: Recent years have witnessed a resurgence of interest in nonlinear multimode optical systems where a host of intriguing effects have been observed that are impossible in single-mode settings. While nonlinearity can provide a rich environment […]
