Statistics and Topology of Fluctuating Ribbons

Kavli Affiliate: L. Mahadevan | First 5 Authors: Ee Hou Yong, Farisan Dary, Luca Giomi, L. Mahadevan, | Summary: Ribbons are a class of slender structures whose length, width, and thickness are widely separated from each other. This scale separation gives a ribbon unusual mechanical properties in athermal macroscopic settings, e.g. it can bend without […]

Atomic fluctuations lifting the energy degeneracy in Si/SiGe quantum dots

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Brian Paquelet Wuetz, Merritt P. Losert, Sebastian Koelling, Lucas E. A. Stehouwer, Anne-Marije J. Zwerver | Summary: Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite attempts to enhance […]

Anomalous Josephson Effect in Topological Insulator-Based Josephson Trijunction

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Zhaozheng Lyu, Guang Yang, Bing Li, Yan-Liang Hou | Summary: We studied anomalous Josephson effect (AJE) in Josephson trijunctions fabricated on Bi$_2$Se$_3$, and found that the AJE in T-shaped trijunctions significantly alters the Majorana phase diagram of the trijunctions, when an in-plane magnetic field is […]

Nonlocal screening dictates the radiative lifetimes of excitations in lead halide perovskites

Kavli Affiliate: David T. Limmer | First 5 Authors: Yoonjae Park, Amael Obliger, David T. Limmer, , | Summary: We use path integral molecular dynamics simulations and theory to elucidate the interactions between charge carriers, as mediated by a lead halide perovskite lattice. We find that the charge-lattice coupling of MAPbI$_3$ results in a repulsive […]

Origins of transverse voltages generated by applied thermal gradients and applied electric fields in ferrimagnetic-insulator/heavy-metal bilayers

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Arnab Bose, Rakshit Jain, Jackson J. Bauer, Robert A. Buhrman, Caroline A. Ross | Summary: We compare thermal-gradient-driven transverse voltages in ferrimagnetic-insulator/heavy-metal bilayers (Tm3Fe5O12/W and Tm3Fe5O12/Pt) to corresponding electrically-driven transverse resistances at and above room temperature. We find for Tm3Fe5O12/W that the thermal and electrical effects […]

Embracing Single Stride 3D Object Detector with Sparse Transformer

Kavli Affiliate: Feng Wang | First 5 Authors: Lue Fan, Ziqi Pang, Tianyuan Zhang, Yu-Xiong Wang, Hang Zhao | Summary: In LiDAR-based 3D object detection for autonomous driving, the ratio of the object size to input scene size is significantly smaller compared to 2D detection cases. Overlooking this difference, many 3D detectors directly follow the […]
