Strong Second Harmonic Generation from Bilayer Graphene with Symmetry Breaking by Redox-Governed Charge Doping

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Mingwen Zhang, Nannan Han, Jing Wang, Zhihong Zhang, Kaihui Liu | Summary: Missing second-order nonlinearity in centrosymmetric graphene overshadows its intriguing optical attribute. Here, we report redox-governed charge doping could effectively break the centrosymmetry of bilayer graphene (BLG), enabling a strong second harmonic generation (SHG) with a […]

Revealing the nature of a Lyman-$α$ halo in a strongly-lensed interacting system at $z=2.92$

Posted by Chicago

Kavli Affiliate: Michael Gladders | First 5 Authors: Manuel Solimano, Jorge González-López, Manuel Aravena, Evelyn Johnston, Cristóbal Moya-Sierralta | Summary: Spatially extended halos of Lyman Alpha (Ly$alpha$) emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of these halos is still hampered by the complex radiative […]

The Simulated Catalogue of Optical Transients and Correlated Hosts (SCOTCH)

Posted by Chicago

Kavli Affiliate: Richard Kessler | First 5 Authors: Martine Lokken, Alexander Gagliano, Gautham Narayan, Renée Hložek, Richard Kessler | Summary: As we observe a rapidly growing number of astrophysical transients, we learn more about the diverse host galaxy environments in which they occur. Host galaxy information can be used to purify samples of cosmological Type […]

Observational Inference on the Delay Time Distribution of Short Gamma-ray Bursts

Posted by Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Michael Zevin, Anya E. Nugent, Susmita Adhikari, Wen-fai Fong, Daniel E. Holz | Summary: The delay time distribution of neutron star mergers provides critical insights into binary evolution processes and the merger rate evolution of compact object binaries. However, current observational constraints on this delay time […]

Boson-fermion duality with subsystem symmetry

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Masahito Yamazaki, Yunqin Zheng, , | Summary: We explore an exact duality in $(2+1)$d between the fermionization of a bosonic theory with a $mathbb{Z}_2$ subsystem symmetry and a fermionic theory with a $mathbb{Z}_2$ subsystem fermion parity symmetry. A typical example is the duality between the […]

The Mysterious Affair of the H$_2$ in AU Mic

Posted by dbos Peking

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Laura Flagg, Christopher Johns-Krull, Kevin France, Gregory Herczeg, Joan Najita | Summary: Molecular hydrogen is the most abundant molecule in the Galaxy and plays important roles for planets, their circumstellar environments, and many of their host stars. We have confirmed the presence of molecular hydrogen in the […]

Ramification theory from homotopical point of view, I

Posted by klaurent Tokyo

Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: We prove the compatibility of pushforward along a proper morphism of an ‘{e}tale constructible sheaf and the pushforward of its characteristic cycle up to $p$-torsion. This was conjectured by Takeshi Saito. For this, we revisit the construction of the characteristic […]
