Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Pavel Sidorenko, Frank Wise, , | Summary: We start an environmentally-stable linear Mamyshev oscillator with electronically-controlled modulated pump and a moving filter. It delivers a 21-nJ pulse that becomes 65 fs in duration after a compressor. Reliable starting into stable mode-locking is found achievable with […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Heming Wang, Lue Wu, Zhiquan Yuan, Kerry Vahala, | Summary: Narrow-linewidth lasers are important to many applications spanning precision metrology to sensing systems. Their miniaturization in the form of on-chip lasers is receiving increasing attention. Here, a noise level that is consistent with a fundamental frequency noise […]
Kavli Affiliate: Cees Dekker | First 5 Authors: Sonja Schmid, Cees Dekker, , , | Summary: Proteins are the active working horses in our body. These biomolecules perform all vital cellular functions from DNA replication and general biosynthesis to metabolic signaling and environmental sensing. While static 3D structures are now readily available, observing the functional […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Jeff Delaune, Jacob Izraelevitz, Larry A. Young, William Rapin, Evgeniy Sklyanskiy | Summary: Mid-Air Deployment (MAD) of a rotorcraft during Entry, Descent and Landing (EDL) on Mars eliminates the need to carry a propulsion or airbag landing system. This reduces the total mass inside the aeroshell by […]

Kavli Affiliate: P. G. Steeneken | First 5 Authors: D. Afanasiev, J. R. Hortensius, M. Matthiesen, S. Mañas-Valero, M. Šiškins | Summary: Magnetic van der Waals materials provide an ideal playground for exploring the fundamentals of low-dimensional magnetism and open new opportunities for ultrathin spin processing devices. The Mermin-Wagner theorem dictates that as in reduced […]
Kavli Affiliate: Cees Dekker | First 5 Authors: Nils Klughammer, Cees Dekker, , , | Summary: Holes in metal films block any transmitting light if the wavelength is much larger than the hole diameter, establishing such nanopores as so-called Zero Mode Waveguides (ZMWs). Molecules on the other hand, can still passage through these holes. We […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Xiao Xue, Bishnu Patra, Jeroen P. G. van Dijk, Nodar Samkharadze, Sushil Subramanian | Summary: The most promising quantum algorithms require quantum processors hosting millions of quantum bits when targeting practical applications. A major challenge towards large-scale quantum computation is the interconnect complexity. In current solid-state qubit […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing, Yang Cui, Naseem Ud Din | Summary: Direct measurements of photoexcited carrier dynamics in nickel are made using few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy at the nickel M$_{2,3}$ edge. It is observed that the core-level absorption lineshape of […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Peng Zhang, Christian Kern, Sijie Sun, David A. Weitz, Pai Wang | Summary: We demonstrate a new class of elastic waves in the bulk: When longitudinal and transverse components propagate at the same speed, rolling waves with a spin that is not parallel to the wave […]
