Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Guy Ohad, Stephen E. Gant, Dahvyd Wing, Jonah B. Haber, María Camarasa-Gómez | Summary: Using both time-dependent density functional theory (TDDFT) and the “single-shot" $GW$ plus Bethe-Salpeter equation ($GW$-BSE) approach, we compute optical band gaps and optical absorption spectra from first principles for eight common binary […]

Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Kavli Affiliate: Feng Wang | First 5 Authors: Sofya Alexeeva, Yu Wang, Gang Zhao, Feng Wang, Yong Wu | Summary: The non-local thermodynamical equilibrium (NLTE) line formation of Y I and Y II is considered in 1D LTE model atmospheres of F-G-K-type stars. The model atom was constructed with the most up-to-date atomic data, including […]

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Jianhua Zhang, Cong Su, Salman Kahn, Huaidong Jiang | Summary: We demonstrate the application of multislice ptychography to a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set. The propagation from the top flake, through the interface, to the bottom flake is […]

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Haozhi Sha, Jianhua Zhang, Cong Su, Salman Kahn | Summary: We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We identify the buried heterointerface between two twisted h-BN flakes with a […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Joohwan Seo, Nikhil Potu Surya Prakash, Xiang Zhang, Changhao Wang, Jongeun Choi | Summary: This paper presents a differential geometric control approach that leverages SE(3) group invariance and equivariance to increase transferability in learning robot manipulation tasks that involve interaction with the environment. Specifically, we employ a […]
