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: K. Birgitta Whaley | First 5 Authors: William J. Huggins, Sam McArdle, Thomas E. O’Brien, Joonho Lee, Nicholas C. Rubin | Summary: Contemporary quantum computers have relatively high levels of noise, making it difficult to use them to perform useful calculations, even with a large number of qubits. Quantum error correction is expected […]
Kavli Affiliate: Graham R. Fleming | First 5 Authors: Akihito Ishizaki, Graham R. Fleming, , , | Summary: Giant strides in ultrashort laser pulse technology have enabled real-time observation of dynamical processes in complex molecular systems. Specifically, the discovery of oscillatory transients in the two-dimensional electronic spectra of photosynthetic systems stimulated a number of theoretical […]
Kavli Affiliate: Carlos Bustamante | First 5 Authors: Kerui Peng, Yana Safonova, Mikhail Shugay, Alice Popejoy, Oscar Rodriguez | Summary: With the advent of high-throughput sequencing technologies, the fields of immunogenomics and adaptive immune receptor repertoire research are facing both opportunities and challenges. Adaptive immune receptor repertoire sequencing (AIRR-seq) has become an increasingly important tool […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Wei Ruan, Yi Chen, Shujie Tang, Jinwoong Hwang, Hsin-Zon Tsai | Summary: Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state whose low-energy behavior is described by a spinon Fermi surface. Directly imaging the resulting spinons, however, is difficult […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Katherine A. Cochrane, Jun-Ho Lee, Christoph Kastl, Jonah B. Haber, Tianyi Zhang | Summary: We demonstrate the creation of a spin-1/2 state via the atomically controlled generation of magnetic carbon radical ions (CRIs) in synthetic two-dimensional transition metal dichalcogenides (TMDs). Hydrogenated carbon impurities located at chalcogen […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Alex M. Ganose, Junsoo Park, Alireza Faghaninia, Rachel Woods-Robinson, Kristin A. Persson | Summary: The electronic transport behaviour of materials determines their suitability for technological applications. We develop an efficient method for calculating carrier scattering rates of solid-state semiconductors and insulators from first principles inputs. The […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Canxun Zhang, Tiancong Zhu, Salman Kahn, Shaowei Li, Birui Yang | Summary: The discovery of interaction-driven insulating and superconducting phases in moir’e van der Waals heterostructures has sparked considerable interest in understanding the novel correlated physics of these systems. While a significant number of studies have […]
Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Connor G. Bischak, Jonathan G. Raybin, Jonathon W. Kruppe, Naomi S. Ginsberg, | Summary: We induce and investigate the coarsening and melting dynamics of an initially static nanoparticle colloidal monolayer at an ionic liquid-vacuum interface, driven by a focused, scanning electron beam. Coarsening occurs through grain […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jie Xu, Vincent K. N. Lau, Shuguang Cui, | Summary: This paper studies a hierarchical over-the-air computation (AirComp) network over a large area, in which multiple relays are exploited to facilitate data aggregation from massive WDs. We present a two-phase amplify-and-forward (AF) relaying protocol. In […]
