Kavli Affiliate: David Muller | First 5 Authors: Sammy Christen, David Müller, Agon Serifi, Ruben Grandia, Georg Wiedebach | Summary: Teleoperated robotic characters can perform expressive interactions with humans, relying on the operators’ experience and social intuition. In this work, we propose to create autonomous interactive robots, by training a model to imitate operator data. […]
Kavli Affiliate: Dan Luo | First 5 Authors: Yuanyuan Wang, Hangting Chen, Dongchao Yang, Weiqin Li, Dan Luo | Summary: We propose Universal target audio Separation (UniSep), addressing the separation task on arbitrary mixtures of different types of audio. Distinguished from previous studies, UniSep is performed on unlimited source domains and unlimited source numbers. We […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Sajid Husain, Maya Ramesh, Xinyan Li, Sergei Prokhorenko, Shashank Kumar Ojha | Summary: Since Felix Bloch’s introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, particularly for non-volatile logic-in-memory […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Adeline Crépieux, Emile Pangburn, Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll | Summary: We compute the (0-11) surface spectral function, the surface density of states (DOS), and the quasiparticle interference (QPI) patterns, both in the normal state and superconducting (SC) state of UTe$_2$. We consider […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll, Bin Hu, Xiaolong Liu | Summary: Although no known material definitely exhibits intrinsic topological superconductivity, where a spin-triplet electron pairing potential $Delta(k)$ has odd parity, UTe2 is now the leading candidate. Ideally, the parity of $Delta(k)$ might be […]
Kavli Affiliate: Katja C. Nowack | First 5 Authors: Ruiheng Bai, Aliakbar Sepehri, Yen-Lee Loh, Anne-Marie Valente-Feliciano, Anna Herr | Summary: We use scanning superconducting quantum interference device (SQUID) microscopy to image vortices in superconducting strips fabricated from NbTiN thin films. We repeatedly cool superconducting strips with different width in an applied magnetic field and […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee, Haoran Lu, Jorge L. Ramirez | Summary: Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally been avoided for making high-quality superconducting resonator […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Harikrishnan KP, Varun Harbola, Jaehong Choi, Kevin J. Crust, Yu-Tsun Shao | Summary: Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materials that lack inversion symmetry. In contrast, the flexoelectric effect […]

Kavli Affiliate: David A. Muller | First 5 Authors: Antonio Gonzalez, Samuel J. Poage, Bernardo Langa, Jr., Deepak Sapkota, Salva Salmani-Rezaie | Summary: The intersection of superconductivity and ferroelectricity hosts a wide range of exotic quantum phenomena. Here, we report on the observation of superconductivity in high-quality tin telluride films grown by molecular beam epitaxy. […]
