Kavli Affiliate: Simon Groblacher | First 5 Authors: Zizheng Li, Naresh Sharma, Bruno Lopez-Rodriguez, Roald van der Kolk, Thomas Scholte | Summary: In the past decade, lithium niobate (LiNbO3 or LN) photonics, thanks to its heat-free and fast electro-optical modulation, second-order non-linearities and low loss, has been extensively investigated. Despite numerous demonstrations of high-performance LN […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Bruno Lopez-Rodriguez, Naresh Sharma, Zizheng Li, Roald van der Kolk, Jasper van der Boom | Summary: Integrated photonic circuits have transformed data communication, biosensing, and light detection and ranging, and hold wide-ranging potential for optical computing, optical imaging and signal processing. These applications often require tunable and […]

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Giacomo Sala, Maria Teresa Mercaldo, Klevis Domi, Stefano Gariglio, Mario Cuoco | Summary: Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of the electronic wavefunctions. These properties are encoded in the quantum metric and Berry curvature. While Berry curvature-mediated transport […]

Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Sebastian Miles, Alberto Bordin, Sebastiaan L. D. ten Haaf, A. Mert Bozkurt | Summary: Quantum dot-superconductor arrays have emerged as a new and promising material platform for realizing Kitaev chains with Majorana zero modes. So far, experiments have implemented a two-site chain with limited protection. […]

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bowy M. La Rivière, Natalia Chepiga, , , | Summary: We study the nature of quantum phase transitions out of $mathbb{Z}_4$ ordered phases in quantum loop models on a zig-zag ladder. We report very rich critical behaviour that includes a pair of Ising transitions, a multi-critical Ashkin-Teller […]

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: It is well-known that quantum algorithms such as Grover’s can provide a quadradic speed-up for unstructured search problems. By adding topological structure to a search problem, we show that it is possible to achieve a constant search-time […]

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We explore the universal signatures of quantum phase transitions that can be extracted with the density matrix renormalization group (DMRG) algorithm applied to quantum chains with a gradient. We present high-quality data collapses for the order parameter and for the […]

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Greta Segantini, Chih-Ying Hsu, Carl Willem Rischau, Patrick Blah, Mattias Matthiesen | Summary: The epitaxial growth of complex oxides enables the production of high-quality films, yet substrate choice is restricted to certain symmetry and lattice parameters, thereby limiting the technological applications of epitaxial oxides. In comparison, […]

Kavli Affiliate: Michael Wimmer | First 5 Authors: Bernhard Kerbl, Andréas Meuleman, Georgios Kopanas, Michael Wimmer, Alexandre Lanvin | Summary: Novel view synthesis has seen major advances in recent years, with 3D Gaussian splatting offering an excellent level of visual quality, fast training and real-time rendering. However, the resources needed for training and rendering inevitably […]

Kavli Affiliate: P. G. Steeneken | First 5 Authors: M. P. Abrahams, J. Martinez, P. G. Steeneken, G. J. Verbiest, | Summary: Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-induced modulation of the compressibility of air. By driving […]
