Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., J. Fernando Barbero G., , , | Summary: We analyze from a geometric perspective the Hamiltonian formulation of a recent modification of the Husain-Kuchavr model where, while preserving the connection as a dynamical variable, the other field is restricted to be the […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Siddharth Tiwary, Siddharth Tiwary, , , | Summary: Spin chains with quenched disorder exhibit rich critical behavior, often captured by real-space renormalization group (RSRG) techniques. However, the physics of such systems in the presence of random measurements (i.e., non-Hermitian dephasing) remains largely unexplored. The interplay between […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Xin Hu, Xin Hu, , , | Summary: We theoretically study spin and valley transport in a TMDC/ferromagnet heterostructure under a perpendicular magnetic field. We find that microwave-driven spin pumping induces a valley-selective spin excitation, a direct consequence of the valley-asymmetric Landau levels in the TMDC conduction […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Yi-Hsien Wu, Yi-Hsien Wu, , , | Summary: Silicon spin qubits are a promising platform for scalable quantum computing due to their compatibility with industrial semiconductor fabrication and the recent scaling to multi-qubit devices. Control fidelities above the 99% fault-tolerant threshold are routinely achieved, but extending high-fidelity […]
Kavli Affiliate: Justus M Kebschull | Authors: Hyopil Kim, Cheng Xu, Craig Washington, Maggie Lowman and Justus M Kebschull | Summary: Brain-wide neural circuits are formed by the diverse axonal branching patterns of many individual neurons. Here we introduce POlNTseq (projections of interest by sequencing), a high-throughput and user-friendly barcoded connectomics method that uses cell […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Teodora-Elena Bulichi, Teodora-Elena Bulichi, , , | Summary: High-redshift active galactic nuclei (AGN) have long been recognized as key probes of early black hole growth and galaxy evolution. However, modeling this population remains difficult due to the wide range of luminosities and black hole masses involved, and […]
Kavli Affiliate: Gang Su | First 5 Authors: Wei Wang, Wei Wang, , , | Summary: We investigate the impact of magnetic flux and the odd-even parity of lattice points $N$ on electron transport in an annular Kitaev chain, with an explanation provided from the energy band perspective. Three transport mechanisms including direct transmission (DT), […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yimin Hao, Yimin Hao, , , | Summary: The submodular knapsack problem (SKP), which seeks to maximize a submodular set function by selecting a subset of elements within a given budget, is an important discrete optimization problem. The majority of existing approaches to solving the SKP are […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: This paper presents a comprehensive study on the asymptotically optimal repair of Reed-Solomon (RS) codes with small sub-packetization, specifically tailored for rack-aware distributed storage systems. Through the utilization of multi-base expansion, we introduce a novel approach that leverages monomials […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Joohwan Seo, Joohwan Seo, , , | Summary: This paper presents a framework for learning vision-based robotic policies for contact-rich manipulation tasks that generalize spatially across task configurations. We focus on achieving robust spatial generalization of the policy for the peg-in-hole (PiH) task trained from a small […]
