Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Eungkyun Kim, Naomi Pieczulewski, Zexuan Zhang, Anna Feduniewicz-Zmuda | Summary: Unlike non-polar semiconductors such as silicon, the broken inversion symmetry of the wide bandgap semiconductor gallium nitride leads to a large electronic polarization along a unique crystal axis. This makes the two surfaces of […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Isidora Araya Day, Sebastian Miles, Hugo K. Kerstens, Daniel Varjas, Anton R. Akhmerov | Summary: A common technique in the study of complex quantum-mechanical systems is to reduce the number of degrees of freedom in the Hamiltonian by using quasi-degenerate perturbation theory. While the Schrieffer–Wolff transformation […]
Kavli Affiliate: Ronald Hanson | First 5 Authors: Arian J. Stolk, Kian L. van der Enden, Marie-Christine Slater, Ingmar te Raa-Derckx, Pieter Botma | Summary: A key challenge towards future quantum internet technology is connecting quantum processors at metropolitan scale. Here, we report on heralded entanglement between two independently operated quantum network nodes separated by […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Erin Kara, Claude Canizares, Deepto Chakrabarty | Summary: Evidence suggests that when compact objects such as black holes and neutron stars form, they may receive a “natal kick,” where the stellar remnant gains momentum. Observational evidence for neutron star kicks is substantial, […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro, Anthony J. Taylor, Antonello Calabrò | Summary: We present a sample of 341 "little red dots" (LRDs) spanning the redshift range $zsim2-11$ using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. These sources are likely heavily-reddened AGN […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Yan-Qiu Zhang, Hao-Xiang Lin, Shao-Lin Xiong, Zhuo Li, Ming-Yu Ge | Summary: Gamma-ray bursts (GRBs) are believed to launch relativistic jets, which generate prompt emission by their internal processes and drive external shocks into surrounding medium, accounting for the long-lasting afterglow emission. However, how the jet powers […]
