Kavli Affiliate: Grace Xing | 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 […]
Kavli Affiliate: Jie Shan | First 5 Authors: Huiying Cui, Qianying Hu, Xuan Zhao, Liguo Ma, Feng Jin | Summary: The study of exciton-polarons has offered profound insights into the many-body interactions between bosonic excitations and their immersed Fermi sea within layered heterostructures. However, little is known about the properties of exciton polarons with interlayer […]
Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Fabian Jerzembeck, You-Sheng Li, Grgur Palle, Zhenhai Hu, Mehdi Biderang | Summary: There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus $c_{66}$ at the critical temperature $T_c$, observed in ultrasound measurements. Such […]
Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide (TMD) semiconductors have emerged as a highly tunable system for the studies of correlated and topological states of matter, such as superconductivity, ferromagnetism, correlated insulators, and topological and Chern […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Dylan Heberle, Noah Flemens, Connor Davis, Philippe Lassonde, Adrien Leblanc | Summary: Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion […]
