Gate-tunable electroresistance in a sliding ferroelectric tunnel junction

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Bozo Vareskic, Finn G. Kennedy, Takashi Taniguchi, Kenji Watanabe, Kenji Yasuda | Summary: We fabricate and measure electrically-gated tunnel junctions in which the insulating barrier is a sliding van der Waals ferroelectric made from parallel-stacked bilayer hexagonal boron nitride and the electrodes are single-layer graphene. Despite […]

Autonomous Human-Robot Interaction via Operator Imitation

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. […]

Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet

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 […]

Quasiparticle interference and spectral function of the UTe$_2$ superconductive surface band

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 […]

Imaging Odd-Parity Quasiparticle Interference in the Superconductive Surface State of UTe2

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 […]
