Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: J. Shen, G. W. Winkler, F. Borsoi, S. Heedt, V. Levajac | Summary: We measure the charge periodicity of Coulomb blockade conductance oscillations of a hybrid InSb-Al island as a function of gate voltage and parallel magnetic field. The periodicity changes from $2e$ to $1e$ at […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Guorui Chen, Aaron L. Sharpe, Eli J. Fox, Shaoxin Wang, Bosai Lyu | Summary: The flat bands resulting from moir’e superlattices in magic-angle twisted bilayer graphene (MATBG) and ABC-trilayer graphene aligned with hexagonal boron nitride (ABC-TLG/hBN) have been shown to give rise to fascinating correlated electron […]
Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Farzad B. Faramarzi, Peter K. Day, Jacob Glasby, Sasha Sypkens, Marco Colangelo | Summary: Superconducting qubits are widely used in quantum computing research and industry. We describe a superconducting kinetic inductance qubit (and introduce the term Kineticon to describe it) operating at W-band frequencies with a nonlinear […]
Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations which closely resemble the Aharanov-Bohm effect. We develop a semiclassical theory of these oscillations and show that they are a consequence of the quasi-2D dispersion […]
Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show that the magnetoresistance oscillations are explained by the Bloch-like oscillations of the out-of-plane electron trajectories. We develop […]
Kavli Affiliate: Alex Zettl | First 5 Authors: Jeffrey D. Cain, Sehoon Oh, Amin Azizi, Scott Stonemeyer, Mehmet Dogan | Summary: Imposing additional confinement in two-dimensional (2D) materials can yield further control over the associated electronic, optical, and topological properties. However, synthesis of ultra-narrow nanoribbons (NRs) remains a challenge, particularly for the transition metal dichalcogenides […]
Kavli Affiliate: Sol M. Gruner | First 5 Authors: Kayla X. Nguyen, Yi Jiang, Michael C. Cao, Prafull Purohit, Ajay K. Yadav | Summary: Orbital angular momentum and torque transfer play central roles in a wide range of magnetic textures and devices including skyrmions and spin-torque electronics(1-4). Analogous topological structures are now also being explored […]

Kavli Affiliate: Oskar Painter | First 5 Authors: Christopher Chamberland, Kyungjoo Noh, Patricio Arrangoiz-Arriola, Earl T. Campbell, Connor T. Hann | Summary: We present a comprehensive architectural analysis for a proposed fault-tolerant quantum computer based on cat codes concatenated with outer quantum error-correcting codes. For the physical hardware, we propose a system of acoustic resonators […]
Kavli Affiliate: Kristin Persson | First 5 Authors: Amalie Trewartha, John Dagdelen, Haoyan Huo, Kevin Cruse, Zheren Wang | Summary: The ongoing COVID-19 pandemic has had far-reaching effects throughout society, and science is no exception. The scale, speed, and breadth of the scientific community’s COVID-19 response has lead to the emergence of new research literature […]
