Kavli Affiliate: Birgitta Whaley | Summary:The finite element method (FEM) is a cornerstone numerical technique for solving partial differential equations (PDEs). Here, we present $textbfQu-FEM$, a fault-tolerant era quantum algorithm for the finite element method. In contrast to other quantum PDE solvers, Qu-FEM preserves the geometric flexibility of FEM by introducing two new primitives, the […]
Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Jocelyn L. Mendes, Jocelyn L. Mendes, , , | Summary: Small polarons remain a significant bottleneck in the realization of efficient devices using transition metal oxides. Routes to engineer small polaron coupling to electronic states and lattice modes to control carrier localization remain unclear. Here, we […]
Kavli Affiliate: Naomi Ginsberg | Summary:Small polarons remain a significant bottleneck in the realization of efficient devices using transition metal oxides. Routes to engineer small polaron coupling to electronic states and lattice modes to control carrier localization remain unclear. Here, we measure the formation of small polarons in CuFeO$_2$ using transient extreme ultraviolet reflection spectroscopy […]
Kavli Affiliate: Felix Fischer | Summary:Pi-conjugated covalent organic frameworks (COFs) provide a versatile platform for the realization of designer quantum nanomaterials. Strong electron-electron correlation within these artificial lattices can give rise to exotic phases of matter. Their experimental realization however requires precise control over orbital symmetry, charge localization, and band dispersion all arising from the […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Xiang Zhang, , , | Summary: IEEE 802.11ax introduces orthogonal frequency division multiple access (OFDMA) to WiFi to support concurrent transmissions to a larger number of users. As bandwidth continues to grow, WiFi channels exhibit increased frequency selectivity, which poses new challenges for MU-MIMO user […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: The construction of the first phase of the High energy FRagment Separator (HFRS Phase-I) has already been completed and it is anticipated to start beam commissioning in autumn 2025. This paper presents the first order and higher order beam […]
Kavli Affiliate: Feng Wang | First 5 Authors: Zhehao Ge, Zhehao Ge, , , | Summary: Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem in condensed matter physics. Progress in this topic has been limited by a lack of single-defect-resolved experimental […]
