Kavli Affiliate: Zheng Zhu | First 5 Authors: Mingjie Zhang, Xuan Zhao, Kenji Watanabe, Takashi Taniguchi, Zheng Zhu | Summary: Many sought-after exotic states of matter are known to emerge close to quantum phase transitions, such as quantum spin liquids (QSL) and unconventional superconductivity. It is thus desirable to experimentally explore systems that can be […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Songfu Cai, Vincent K. N. Lau, , | Summary: This paper studies a sequential task offloading problem for a multiuser mobile edge computing (MEC) system. We consider a dynamic optimization approach, which embraces wireless channel fluctuations and random deep neural network (DNN) task arrivals over […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Hebai Chen, Hao Yang, Rui Zhang, Xiang Zhang, | Summary: Characterizing existence or not of periodic orbit is a classical problem and it has both theoretical importance and many real applications. Here, several new criterions on nonexistence of periodic orbits of the planar dynamical system $dot x=y,~dot […]
Kavli Affiliate: Wei Gao | First 5 Authors: Hao Liu, Hui Yuan, Junhui Hou, Raouf Hamzaoui, Wei Gao | Summary: We propose a generative adversarial network for point cloud upsampling, which can not only make the upsampled points evenly distributed on the underlying surface but also efficiently generate clean high frequency regions. The generator of […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Amin Rezaei Akbarieh, Sobhan Kazempour, Lijing Shao, , | Summary: As massive gravity and its extensions offer physically well-defined gravitational theories with a nonzero graviton mass, we present a new extension of the de Rham-Gabadadze-Tolley (dRGT)massive gravity, which is tachyonic massive gravity theory. We firstly introduce the […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Jozef Bucko, Frank Schäfer, František Herman, Rebekka Garreis, Chuyao Tong | Summary: Bilayer graphene is a nanomaterial that allows for well-defined, separated quantum states to be defined by electrostatic gating and, therefore, provides an attractive platform to construct tunable quantum dots. When a magnetic field perpendicular to […]

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Sebastian Wagner-Carena, Jelle Aalbers, Simon Birrer, Ethan O. Nadler, Elise Darragh-Ford | Summary: Constraining the distribution of small-scale structure in our universe allows us to probe alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a unique window into small dark matter halos ($<10^{10} […]
