Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Dahvyd Wing, Guy Ohad, Jonah B. Haber, Marina R. Filip, Stephen E. Gant | Summary: Accurate prediction of fundamental band gaps of crystalline solid state systems entirely within density functional theory is a long standing challenge. Here, we present a simple and inexpensive method that achieves […]
Kavli Affiliate: Daniel Needleman | First 5 Authors: Won-Dong Jang, Donglai Wei, Xingxuan Zhang, Brian Leahy, Helen Yang | Summary: Blastomere instance segmentation is important for analyzing embryos’ abnormality. To measure the accurate shapes and sizes of blastomeres, their amodal segmentation is necessary. Amodal instance segmentation aims to recover the complete silhouette of an object […]

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Dimas G. de Oteyza, Alejandro Pérez Paz, Yen-Chia Chen, Zahra Pedramrazi, Alexander Riss | Summary: We investigate the thermally-induced cyclization of 1,2 – bis(2 – phenylethynyl)benzene on Au(111) using scanning tunneling microscopy and computer simulations. Cyclization of sterically hindered enediynes is known to proceed via two […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec, Ivan Prieto, Amir Sammak | Summary: Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promising platform for creating hybrid superconductor-semiconductor devices. A key challenge […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary. A. Steele, , | Summary: Driving quantum systems periodically in time plays an essential role in the coherent control of quantum states. The rotating wave approximation (RWA) is a good approximation technique for weak and nearly-resonance driven fields. However, these experiments […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Anais Abramian, Emmanuel Virot, Emilio Lozano, Shmuel M. Rubinstein, Tobias M. Schneider | Summary: From soda cans to space rockets, thin-walled cylindrical shells are abundant, offering exceptional load carrying capacity at relatively low weight. However, the actual load at which any shell buckles and collapses is […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Pasquale Cilibrizzi, Xiaoze Liu, Peiyao Zhang, Chenzhe Wang, Quanwei Li | Summary: The newly discovered valley degree of freedom in atomically thin two-dimensional transition metal dichalcogenides offers a promising platform to explore rich nonlinear physics, such as spinor Bose-Einstein condensate (BEC) and novel valleytronics applications. However, the […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Kim Pöyhönen, Daniel Varjas, Michael Wimmer, Anton R. Akhmerov, | Summary: Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that the relationship between superconducting pairing and time reversal breaking imposes rigorous bounds […]
