Pomeranchuk Effect and Tunable Quantum Phase Transitions in 3L-MoTe2/WSe2

Posted by klaurent UCAS

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 […]

PUFA-GAN: A Frequency-Aware Generative Adversarial Network for 3D Point Cloud Upsampling

Posted by klaurent Caltech

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 […]

Cosmology and perturbations in tachyonic massive gravity

Posted by klaurent Peking

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 […]

Automated reconstruction of bound states in bilayer graphene quantum dots

Posted by klaurent Delft

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 […]
