Kavli Affiliate: Timon Idema | First 5 Authors: Carsten T. van de Kamp, George Dadunashvili, Johan L. A. Dubbeldam, Timon Idema, | Summary: Order can spontaneously emerge from seemingly noisy interactions between biological agents, like a flock of birds changing their direction of flight in unison, without a leader or an external cue. We are […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Agnes Valenti, Guliuxin Jin, Julian Léonard, Sebastian D. Huber, Eliska Greplova | Summary: Large-scale quantum devices provide insights beyond the reach of classical simulations. However, for a reliable and verifiable quantum simulation, the building blocks of the quantum device require exquisite benchmarking. This benchmarking of large scale […]
Kavli Affiliate: Ronald Hanson | First 5 Authors: Matteo Pompili, Sophie L. N. Hermans, Simon Baier, Hans K. C. Beukers, Peter C. Humphreys | Summary: The distribution of entangled states across the nodes of a future quantum internet will unlock fundamentally new technologies. Here we report on the experimental realization of a three-node entanglement-based quantum […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Titus Neupert, Mark H Fischer, Eliska Greplova, Kenny Choo, Michael Denner | Summary: This is an introductory machine learning course specifically developed with STEM students in mind. We discuss supervised, unsupervised, and reinforcement learning. The notes start with an exposition of machine learning methods without neural networks, […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Haining Pan, Chun-Xiao Liu, Michael Wimmer, Sankar Das Sarma, | Summary: Majorana zero modes can appear at the wire ends of a 1D topological superconductor and manifest themselves as a quantized zero-bias conductance peak in the tunneling spectroscopy of normal-superconductor junctions. However, in superconductor-semiconductor hybrid nanowires, zero-bias […]
Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Neil Sinclair, Daniel Oblak, Erhan Saglamyurek, Rufus L. Cone, Charles W. Thiel | Summary: We characterize the optical coherence and energy-level properties of the 795 nm $^3$H$_6$ to $^3$H$_4$ transition of Tm$^{3+}$ in a Ti$^{4+}$:LiNbO$_{3}$ waveguide at temperatures as low as 0.65 K. Coherence properties are measured […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, Frédéric Mila, , , | Summary: The recent investigation of chains of Rydberg atoms has brought back the problem of commensurate-incommensurate transitions into the focus of current research. In 2D classical systems, or in 1D quantum systems, the commensurate melting of a period-p phase with […]
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: 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 […]
