Tunable strong coupling of mechanical resonance between spatially separated FePS$_3$ nanodrums

Posted by klaurent July 2, 2021Delft

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Makars Šiškins, Ekaterina Sokolovskaya, Martin Lee, Samuel Mañas-Valero, Dejan Davidovikj | Summary: Coupled nanomechanical resonators made of two-dimensional materials are promising for processing information with mechanical modes. However, the challenge for these types of systems is to control the coupling. Here, we demonstrate […]

Lattice Renormalization of Quantum Simulations

Posted by klaurent July 2, 2021Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. […]

Constraining particle acceleration in Sgr A* with simultaneous GRAVITY, Spitzer, NuSTAR and Chandra observations

Posted by klaurent July 2, 2021Stanford

Kavli Affiliate: R. Morris | First 5 Authors: R. Abuter, A. Amorim, M. Bauböck, F. Baganoff, J. P. Berge | Summary: We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the $M$-, $K$-, and $H$-bands in the mid- and near-infrared and in […]

A long-period substellar object exhibiting a single transit in Kepler

Posted by klaurent June 30, 2021MIT

Kavli Affiliate: Saul Rappaport | First 5 Authors: Samuel N. Quinn, Saul Rappaport, Andrew Vanderburg, Jason D. Eastman, Lorne A. Nelson | Summary: We report the detection of a single transit-like signal in the Kepler data of the slightly evolved F star KIC4918810. The transit duration is ~45 hours, and while the orbital period ($Psim10$ […]

Evidence of Accretion Burst: The Viscously Heated Inner Disk of the Embedded Protostar IRAS 16316-1540

Posted by klaurent June 30, 2021Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee, Gregory J. Herczeg, Sunkyung Park | Summary: Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to their thick envelope and the rarity of […]
