Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Anton R. Akhmerov, Daniel Varjas, , | Summary: Protection of topological surface states by reflection symmetry breaks down when the boundary of the sample is misaligned with one of the high symmetry planes of the crystal. We demonstrate that this limitation is removed in […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Kristin A. Persson | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]

Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Logan Wright, Demetrios Christodoulides | Summary: An equilibrium thermodynamic framework that describes highly-multimode optical processes was introduced recently. This theory predicts the outcomes of complex linear and nonlinear multimode interactions based on thermodynamic principles and provides analytic results for the distributions […]
Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Nicholas Bender, Logan Wright | Summary: Recent years have witnessed a resurgence of interest in nonlinear multimode optical systems where a host of intriguing effects have been observed that are impossible in single-mode settings. While nonlinearity can provide a rich environment […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Matthijs H. J. de Jong, Jie Li, Claus Gärtner, Richard A. Norte, Simon Gröblacher | Summary: Studying the interplay between multiple coupled mechanical resonators is a promising new direction in the field of optomechanics. Understanding the dynamics of the interaction can lead to rich new effects, such […]
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 […]
