$Γ$-VAE: Curvature regularized variational autoencoders for uncovering emergent low dimensional geometric structure in high dimensional data

Posted by dbos Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Jason Z. Kim, Nicolas Perrin-Gilbert, Erkan Narmanli, Paul Klein, Christopher R. Myers | Summary: Natural systems with emergent behaviors often organize along low-dimensional subsets of high-dimensional spaces. For example, despite the tens of thousands of genes in the human genome, the principled study of genomics is fruitful […]

Dichotomous Dynamics of Magnetic Monopole Fluids

Posted by dbos Cornell

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Chun-Chih Hsu, Hiroto Takahashi, Fabian Jerzembeck, Jahnatta Dasini, Chaia Carroll | Summary: A recent advance in the study of emergent magnetic monopoles was the discovery that monopole motion is restricted to dynamical fractal trajectories (J. Hall’en et al, Science 378, 1218 (2022)) thus explaining the […]

Reducing the error rate of a superconducting logical qubit using analog readout information

Posted by dbos Delft

Kavli Affiliate: Leonardo Dicarlo | First 5 Authors: Hany Ali, Jorge Marques, Ophelia Crawford, Joonas Majaniemi, Marc Serra-Peralta | Summary: Quantum error correction enables the preservation of logical qubits with a lower logical error rate than the physical error rate, with performance depending on the decoding method. Traditional error decoding approaches, relying on the binarization […]

VisRec: A Semi-Supervised Approach to Radio Interferometric Data Reconstruction

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Haitao Wang, Qiong Luo, Feng Wang, Hejun Wu | Summary: Radio telescopes produce visibility data about celestial objects, but these data are sparse and noisy. As a result, images created on raw visibility data are of low quality. Recent studies have used deep learning models […]

Controllable suppression of the unconventional superconductivity in bulk and thin-film Sr$_{2}$RuO$_{4}$ via high-energy electron irradiation

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jacob P. Ruf, Hilary M. L. Noad, Romain Grasset, Ludi Miao, Elina Zhakina | Summary: In bulk Sr$_{2}$RuO$_{4}$, the strong sensitivity of the superconducting transition temperature $T_{text{c}}$ to nonmagnetic impurities provides robust evidence for a superconducting order parameter that changes sign around the Fermi surface. In […]

Signatures of Majorana protection in a three-site Kitaev chain

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Alberto Bordin, Chun-Xiao Liu, Tom Dvir, Francesco Zatelli, Sebastiaan L. D. ten Haaf | Summary: Majorana zero modes (MZMs) are non-Abelian excitations predicted to emerge at the edges of topological superconductors. One proposal for realizing a topological superconductor in one dimension involves a chain of spinless fermions, […]
