A Time-Dependent Spectral Analysis of $γ$ Cassiopeiae

Kavli Affiliate: Moritz Guenther | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón, Dustin K. Swarm, Joy S. Nichols | Summary: We investigated the temporal and spectral features of $gamma$ Cassiopeiae’s X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the X-ray […]

Exploiting epitaxial strained germanium for scaling low noise spin qubits at the micron-scale

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Lucas E. A. Stehouwer, Cécile X. Yu, Barnaby van Straaten, Alberto Tosato, Valentin John | Summary: Disorder in the heterogeneous material stack of semiconductor spin qubit systems introduces noise that compromises quantum information processing, posing a challenge to coherently control large-scale quantum devices. Here, we exploit low-disorder […]

Sobolev Versus Homogeneous Sobolev Extension

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Riddhi Mishra, Zheng Zhu, , | Summary: In this paper, we study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, we obtain the following results. 1- Let $1leq qleq pleq infty$. Then a bounded $(L^{1, p}, L^{1, q})$-extension domain is also […]

Beyond Coleman’s Instantons

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: In the absence of gravity, Coleman’s theorem states that the $O(4)$-symmetric instanton solution, which is regular at the origin and exponentially decays at infinity, gives the lowest action. Perturbatively, this implies that any small deformation from $O(4)$-symmetry gives […]

Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Kavli Affiliate: Eric D. Siggia | Authors: Stefano Fusi and Liam Paninski | Summary: The brain is highly structured both at anatomical and functional levels. However, within individual brain areas, neurons often exhibit very diverse and seemingly disorganized responses. A more careful analysis shows that these neurons can sometimes be grouped together into specialized subpopulations […]
