Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihang Yin, Siyu Huang, Xiang Zhang, , | Summary: Deep neural networks (DNNs) have shown superior performances on various multimodal learning problems. However, it often requires huge efforts to adapt DNNs to individual multimodal tasks by manually engineering unimodal features and designing multimodal feature fusion strategies. This […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Jean-Loup Ville, Alexis Morvan, Akel Hashim, Ravi K. Naik, Marie Lu | Summary: The success of the current generation of Noisy Intermediate-Scale Quantum (NISQ) hardware shows that quantum hardware may be able to tackle complex problems even without error correction. One outstanding issue is that of coherent […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Sophie F. Weber, Jeffrey B. Neaton, , , | Summary: Recent experiments on the antiferromagnetic intercalated transition metal dichalcogenide $mathrm{Fe_{1/3}NbS_2}$ have demonstrated reversible resistivity switching by application of orthogonal current pulses below its magnetic ordering temperature, making $mathrm{Fe_{1/3}NbS_2}$ promising for spintronics applications. Here, we perform density […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Paul K. Todd, Matthew J. McDermott, Christopher L. Rom, Adam A. Corrao, Jonathan J. Denney | Summary: In sharp contrast to molecular synthesis, materials synthesis is generally presumed to lack selectivity. The few known methods of designing selectivity in solid-state reactions have limited scope, such as […]
Kavli Affiliate: David T. Limmer | First 5 Authors: David T. Limmer, Chloe Y. Gao, Anthony R. Poggioli, , | Summary: Understanding transport processes in complex nanoscale systems, like ionic conductivities in nanofluidic devices or heat conduction in low dimensional solids, poses the problem of examining fluctuations of currents within nonequilibrium steady states and relating […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: James O’Sullivan, Oscar W. Kennedy, Kamanasish Debnath, Joseph Alexander, Christoph W. Zollitsch | Summary: As in conventional computing, key attributes of quantum memories are high storage density and, crucially, random access, or the ability to read from or write to an arbitrarily chosen register. However, achieving such […]
Kavli Affiliate: Ting Xu | First 5 Authors: Ting Xu, Zi-Shuai Wang, Xuan-Hua Li, Wei E. I. Sha, | Summary: Understanding and quantifying the main loss factors affecting the power conversion efficiency of perovskite solar cells are urgently needed. In this work, based on semiconductor physics, the expressions of bulk and surface recombination currents are […]
Kavli Affiliate: Feng Wang | First 5 Authors: Haifeng Ji, Feng Wang, Jinru Chen, Zhilin Li, | Summary: This paper presents a new parameter free partially penalized immersed finite element method and convergence analysis for solving second order elliptic interface problems. A lifting operator is introduced on interface edges to ensure the coercivity of the […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Nicholas Dale, Ryo Mori, M. Iqbal Bakti Utama, Jonathan D. Denlinger, Conrad Stansbury | Summary: Electron-hole asymmetry is a fundamental property in solids that can determine the nature of quantum phase transitions and the regime of operation for devices. The observation of electron-hole asymmetry in graphene and […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Tessa Cookmeyer, Johannes Motruk, Joel E. Moore, , | Summary: At strong repulsion, the triangular-lattice Hubbard model is described by $s=1/2$ spins with nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120$^circ$ order. Using the infinite density matrix renormalization group and exact diagonalization, we study the effect […]
