Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qiao Wang, , , | Summary: This paper endeavors to learn time-varying graphs by using structured temporal priors that assume underlying relations between arbitrary two graphs in the graph sequence. Different from many existing chain structure based methods in which the priors like temporal homogeneity […]
Kavli Affiliate: G. Ravichandran | First 5 Authors: N. R. Brodnik, S. Brach, C. M. Long, G. Ravichandran, B. Bourdin | Summary: Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the resistance of a medium to […]
Kavli Affiliate: Frank Wise | First 5 Authors: Henry Haig, Pavel Sidorenko, Anirban Dhar, Nilotpal Choudhury, Ranjan Sen | Summary: We present a spatiotemporally mode-locked Mamyshev oscillator. A wide variety of multimode mode-locked states, with varying degrees of spatiotemporal coupling, are observed. We find that some control of the modal content of the output beam […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Kitae Eom, Hanjong Paik, Jinsol Seo, Neil Campbell, Evgeny Y. Tsymbal | Summary: The prospect of 2-dimensional electron gases (2DEGs) possessing high mobility at room temperature in wide-bandgap perovskite stannates is enticing for oxide electronics, particularly to realize transparent and high-electron mobility transistors. Nonetheless only a […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Paolo Celli, Ilaria Nunzi, Andrea Calabrese, Stefano Lenci, Chiara Daraio | Summary: We show that shear waves traveling towards the surface of a half-space medium can be attenuated via buried one-dimensional arrays of resonators — here called metapiles — arranged according to sparse patterns around a site […]

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Cham, Saba Karimeddiny, Vishakha Gupta, Joseph A. Mittelstaedt, Daniel C. Ralph | Summary: We measure spin-orbit torque generated by exfoliated layers of the low-symmetry semi-metal ZrTe$_3$ using the spin-torque ferromagnetic resonance (ST-FMR) technique. When the ZrTe$_3$ has a thickness greater than about 10 nm, […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Jelmer M. Boter, Juan P. Dehollain, Jeroen P. G. van Dijk, Yuanxing Xu, Toivo Hensgens | Summary: One of the main bottlenecks in the pursuit of a large-scale–chip-based quantum computer is the large number of control signals needed to operate qubit systems. As system sizes scale up, […]
Kavli Affiliate: J. C. Davis | First 5 Authors: Zengyi Du, Hui Li, Sanghyun Joo, Elizabeth P. Donoway, Jinho Lee | Summary: When Cooper pairs are formed with finite center-of-mass momentum, the defining characteristic is a spatially modulating superconducting energy gap $Delta(r)$. Recently, this concept has been generalized to the pair density wave (PDW) state […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Saba Karimeddiny, Thow Min Cham, Daniel C. Ralph, Yunqiu Kelly Luo, | Summary: We adapt Sagnac interferometry for magneto-optic Kerr effect measurements of spin-orbit-torque-induced magnetic tilting in thin-film magnetic samples. The high sensitivity of Sagnac interferometry permits for the first time optical quantification of spin-orbit torque […]
