Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Lena N. Majer, Tolga Acartürk, Peter A. van Aken, Wolfgang Braun, Luca Camuti | Summary: Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for adsorption-controlled homoepitaxial growth of c-plane sapphire. […]
Kavli Affiliate: Itai Cohen | First 5 Authors: Stephen J. Thornton, Danilo B. Liarte, Itai Cohen, James P. Sethna, | Summary: Rigidity transitions induced by the formation of system-spanning disordered rigid clusters, like the jamming transition, can be well-described in most physically relevant dimensions by mean-field theories. However, we lack a theoretical description of these […]
Kavli Affiliate: Itai Cohen | First 5 Authors: Stephen J. Thornton, Danilo B. Liarte, Itai Cohen, James P. Sethna, | Summary: Rigidity transitions induced by the formation of system-spanning disordered rigid clusters, like the jamming transition, can be well-described in most physically relevant dimensions by mean-field theories. A dynamical mean-field theory commonly used to study […]
Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Juan Felipe Mendez-Valderrama, Sunghoon Kim, Debanjan Chowdhury, , | Summary: Moir’e transition metal dichalcogenide (TMD) materials provide an ideal playground for studying the combined interplay of strong interactions and band-topology over a range of electronic fillings. Here we investigate the panoply of interaction-induced electronic phases that arise […]
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: 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: Gregory D. Fuchs | First 5 Authors: Jae-Pil So, Jialun Luo, Jaehong Choi, Brendan McCullian, Gregory D. Fuchs | Summary: Silicon vacancy (V$_{Si}$) centers in 4H-silicon carbide have emerged as a strong candidate for quantum networking applications due to their robust electronic and optical properties including a long spin coherence lifetime and bright, […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Drake Niedzielski, Brendan D. Faeth, Berit H. Goodge, Mekhola Sinha, Tyrel M. McQueen | Summary: Common belief is that the large band shifts observed in incommensurate misfit compounds, e.g. (LaSe)1.14(NbSe2)2, are due to interlayer charge transfer. In contrast, our analysis, based on both ARPES measurements and […]
Kavli Affiliate: Chris Xu | First 5 Authors: Chris Xu, , , , | Summary: We prove nonhalting of the Turing machine dubbed "Skelet #17", known to be one of the toughest 5-state, 2-symbol Turing machines to analyze. Combined with the efforts of The Busy Beaver Challenge, we are therefore able to show that BB(5), […]
Kavli Affiliate: Dan Luo | First 5 Authors: Chaoran Zhang, Lixin Zou, Dan Luo, Min Tang, Xiangyang Luo | Summary: In recent years, Large Language Models (LLMs) have demonstrated remarkable capabilities across a wide array of text-centric tasks. However, their `large’ scale introduces significant computational and storage challenges, particularly in managing the key-value states of […]
