Kavli Affiliate: Francis J. Doyle | First 5 Authors: Lukas Ortmann, Dawei Shi, Eyal Dassau, Francis J. Doyle III, Berno J. E. Misgeld | Summary: The human insulin-glucose metabolism is a time-varying process, which is partly caused by the changing insulin sensitivity of the body. This insulin sensitivity follows a circadian rhythm and its effects […]
Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Neil Sinclair, Daniel Oblak, Erhan Saglamyurek, Rufus L. Cone, Charles W. Thiel | Summary: We characterize the optical coherence and energy-level properties of the 795 nm $^3$H$_6$ to $^3$H$_4$ transition of Tm$^{3+}$ in a Ti$^{4+}$:LiNbO$_{3}$ waveguide at temperatures as low as 0.65 K. Coherence properties are measured […]
Kavli Affiliate: David A. Muller | First 5 Authors: Yu-Tsun Shao, Sujit Das, Zijian Hong, Ruijuan Xu, Swathi Chandrika | Summary: Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya interaction in magnetic skyrmions. With the discovery of topologically-stable […]
Kavli Affiliate: David Muller | First 5 Authors: David Müller, Yurii Nesterov, Vladimir Shikhman, , | Summary: Recently, there is growing interest and need for dynamic pricing algorithms, especially, in the field of online marketplaces by offering smart pricing options for big online stores. We present an approach to adjust prices based on the observed […]
Kavli Affiliate: Paul Alivisatos | First 5 Authors: Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria, John P. Philbin, David A. Hanifi | Summary: Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxations in nanocrystals are not understood. Here, femtosecond electron diffraction measurements corroborated by […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Paul Dieterle, Ariel Amir, , , | Summary: Scientists have observed and studied diffusive waves in contexts as disparate as population genetics and cell signaling. Often, these waves are propagated by discrete entities or agents, such as individual cells in the case of cell signaling. For a […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, Frédéric Mila, , , | Summary: The recent investigation of chains of Rydberg atoms has brought back the problem of commensurate-incommensurate transitions into the focus of current research. In 2D classical systems, or in 1D quantum systems, the commensurate melting of a period-p phase with […]
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 […]
