Kavli Affiliate: Joel E. Moore | First 5 Authors: Tessa Cookmeyer, Joel E. Moore, , , | Summary: There have been substantial recent efforts, both experimentally and theoretically, to find a material realization of the Kitaev spin-liquid–the ground state of the exactly solvable Kitaev model on the honeycomb lattice. Candidate materials are now plentiful, but […]
Kavli Affiliate: Wei Gao | First 5 Authors: Yiqing Xu, Wei Gao, David Hsu, , | Summary: Inverse reinforcement learning (IRL) seeks to infer a cost function that explains the underlying goals and preferences of expert demonstrations. This paper presents receding horizon inverse reinforcement learning (RHIRL), a new IRL algorithm for high-dimensional, noisy, continuous systems […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Michelle C. Anderson, Addison J. Schile, David T. Limmer, , | Summary: We present a means of studying rare reactive pathways in open quantum systems using Transition Path Theory and ensembles of quantum jump trajectories. This approach allows for elucidation of reactive paths for dissipative, nonadiabatic […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ya-Jing Ma, Feng Wang, Xian-Yuan Wu, Kai-Yuan Cai, | Summary: This paper focuses on the extreme-value problem for Shannon entropy of the joint distribution with given marginals. It is proved that the minimum-entropy coupling must be of order-preserving, while the maximum-entropy coupling coincides with the independent one. […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Julius Wanner, Eric Sihite, Alireza Ramezani, Morteza Gharib, | Summary: The feasibility of performing airborne and ground manipulation, perception, and reconnaissance using wheeled rovers, unmanned aerial vehicles, CubeSats, SmallSats and more have been evaluated before. Among all of these solutions, balloon-based systems possess merits that make them […]

Kavli Affiliate: Feng Wang | First 5 Authors: Guangke Chen, Zhe Zhao, Fu Song, Sen Chen, Lingling Fan | Summary: Speaker recognition systems (SRSs) have recently been shown to be vulnerable to adversarial attacks, raising significant security concerns. In this work, we systematically investigate transformation and adversarial training based defenses for securing SRSs. According to […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Hyunseong Kim, Christian Jünger, Alexis Morvan, Edward S. Barnard, William P. Livingston | Summary: As superconducting quantum processors increase in complexity, techniques to overcome constraints on frequency crowding are needed. The recently developed method of laser-annealing provides an effective post-fabrication method to adjust the frequency of superconducting […]
Kavli Affiliate: Ali Hajimiri | First 5 Authors: Volkan Gurses, Reza Fatemi, Aroutin Khachaturian, Ali Hajimiri, | Summary: We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circuits with two different control schemes: pulse amplitude modulation (PAM) and pulse width modulation […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Cham, Saba Karimeddiny, Avalon H. Dismukes, Xavier Roy, Daniel C. Ralph | Summary: We report measurements of gigahertz-frequency antiferromagnetic resonances that are anisotropic as a function of the direction of applied magnetic field relative to the crystal axes in the van der Waals easy-axis […]
