Kavli Affiliate: Xiang Zhang | First 5 Authors: Ziyu Liu, Azadeh Alavi, Minyi Li, Xiang Zhang, | Summary: Self-supervised contrastive learning has become a key technique in deep learning, particularly in time series analysis, due to its ability to learn meaningful representations without explicit supervision. Augmentation is a critical component in contrastive learning, where different […]
Kavli Affiliate: Wei Gao | First 5 Authors: Yan Wang, Wei Gao, Qi Zhang, Jiajia Liu, Feng Shu | Summary: In this paper, channel estimation of an active intelligent reflecting surface (IRS) aided uplink Internet of Things (IoT) network is investigated. Firstly, the least square (LS) estimators for the direct channel and the cascaded channel […]

Kavli Affiliate: Andrei Faraon | First 5 Authors: Tian Xie, Rikuto Fukumori, Jiahui Li, Andrei Faraon, | Summary: Microwave-to-optical transduction of single photons will play an essential role in interconnecting future superconducting quantum devices, with applications in distributed quantum computing and secure communications. Various transducers that couple microwave and optical modes via an optical drive […]
Kavli Affiliate: Paul Alivisatos | First 5 Authors: Samuel P. Gleason, Jakob C. Dahl, Mahmoud Elzouka, Xingzhi Wang, Dana O. Byrne | Summary: The development of a colloidal synthesis procedure to produce nanomaterials of a specific size with high shape and size purity is often a time consuming, iterative process. This is often due to […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Bruno Lopez-Rodriguez, Naresh Sharma, Zizheng Li, Roald van der Kolk, Jasper van der Boom | Summary: Integrated photonic circuits have transformed data communication, biosensing, and light detection and ranging, and hold wide-ranging potential for optical computing, optical imaging and signal processing. These applications often require tunable and […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Rohit Rana, David T. Limmer, , , | Summary: We use path integral Monte Carlo to study the energetics of excitons in layered, hybrid organic-inorganic perovskites in order to elucidate the relative contributions of dielectric confinement and electron-phonon coupling. While the dielectric mismatch between polar perovskite […]

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, , , , | Summary: The transition from classical physics to quantum mechanics has been mysterious. Here, we derive the space-independent von Neumann equation for electron spin mathematically from the classical Bloch or Majorana–Bloch equation, which is also derived. Subsequently, the space-independent Schr"odinger–Pauli […]
Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Giacomo Sala, Maria Teresa Mercaldo, Klevis Domi, Stefano Gariglio, Mario Cuoco | Summary: Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of the electronic wavefunctions. These properties are encoded in the quantum metric and Berry curvature. While Berry curvature-mediated transport […]
