Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: Arrays of Rydberg atoms have appeared as a remarkably rich playground to study quantum phase transitions in one dimension. One of the biggest puzzles that was brought forward in this context are chiral phase transitions out of density waves. Theoretically […]
Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Jasper R. van der Veen, Silvia Hidalgo Martinez, Albert Wieland, Matteo De Pellegrin, Rick Verweij | Summary: Multicellular cable bacteria display an exceptional form of biological conduction, channeling electrical currents across centimeter distances through a regular network of protein fibers embedded in the […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bernhard Lüscher, Frédéric Mila, Natalia Chepiga, , | Summary: We investigate the nature of the phase transitions in the quantum Ashkin-Teller chain in the presence of chiral perturbations. We locate the Lifshitz line separating a region of direct chiral transitions from the region where the transition is […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Valentin John, Francesco Borsoi, Zoltán György, Chien-An Wang, Gábor Széchenyi | Summary: Electrically driven spin resonance is a powerful technique for controlling semiconductor spin qubits. However, it faces challenges in qubit addressability and off-resonance driving in larger systems. We demonstrate coherent bichromatic Rabi control of quantum dot […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Anton R. Akhmerov, Ion Cosma Fulga, | Summary: The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Wenye Ji, Jin Chang2, He-Xiu Xu, Jian Rong Gao, Simon Gröblacher | Summary: As a two-dimensional planar material with low depth profile, a metasurface can generate non-classical phase distributions for the transmitted and reflected electromagnetic waves at its interface. Thus, it offers more flexibility to control the […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: A. Mert Bozkurt, Jasper Brookman, Valla Fatemi, Anton R. Akhmerov, | Summary: We present a systematic method to design arbitrary energy-phase relations using parallel arms of two series Josephson tunnel junctions each. Our approach employs Fourier engineering in the energy-phase relation of each arm and the […]
