Kavli Affiliate: Farhan Rana | First 5 Authors: Chandrashekhar Savant, Ved Gund, Kazuki Nomoto, Takuya Maeda, Shubham Jadhav | Summary: We report the properties of molecular beam epitaxy deposited AlBN thin films on a recently developed epitaxial nitride metal electrode Nb2N. While a control AlN thin film exhibits standard capacitive behavior, distinct ferroelectric switching is […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Saianeesh K. Haridas, Zeeshan Ahmed, Tanay Bhandarkar, Mark Devlin, Simon Dicker | Summary: The Simons Observatory (SO) is a cosmic microwave background experiment composed of three 0.42 m Small Aperture Telescopes (SATs) and one 6 m Large Aperture Telescope (LAT) in the Atacama Desert of Chile. The […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sebastian Kiehlmann, Philipe Vergara De La Parra, Andrew Sullivan, A. Synani, Ioannis Liodakis | Summary: Haystack and Owens Valley Radio Observatory (OVRO) observations recently revealed strong sinusoidal total flux density variations that maintained coherence between 1975 and 2021 in the blazar PKS 2131-021 ($z=1.283)$. This was interpreted […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Daniel G. Chica, Kenji Watanabe, Takashi Taniguchi, Xavier Roy | Summary: Antiferromagnetic spintronics offers the potential for higher-frequency operations compared to ferromagnetic spintronics and improved insensitivity to magnetic fields. However, previous electrical techniques to detect antiferromagnetic dynamics have required millimeter-scale samples to […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Zhaoxuan Liu, Manda Banerji, Tomoko Suzuki | Summary: We present a study of the molecular gas in five closely-spaced ($R_{perp}<20$ kpc) dual quasars ($L_{rm bol}gtrsim10^{44}~mathrm{erg~s}^{-1}$) at redshifts $0.4<z<0.8$ with the Atacama Large Millimeter/submillimeter Array. The dual quasar phase represents a distinctive […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Zizheng Li, Naresh Sharma, Bruno Lopez-Rodriguez, Roald van der Kolk, Thomas Scholte | Summary: In the past decade, lithium niobate (LiNbO3 or LN) photonics, thanks to its heat-free and fast electro-optical modulation, second-order non-linearities and low loss, has been extensively investigated. Despite numerous demonstrations of high-performance LN […]
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, Feng Shu, Rongen Dong, Wei Gao, Qi Zhang | 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 […]
