Enhancement of superconducting stiffness in hybrid superconducting-metallic bilayers

J. E. Ebot, Lorenzo Pizzino, Sam Mardazad, Johannes S. Hofmann, Thierry Giamarchi, Adrian Kantian · 2026

Boosting superconductivity by metallic reservoirs is the essence of Kivelson's bilayer proposal. One layer provides pairing to the electrons, while the weakly coupled metal provides additional phase…

Effective length scales, dispersion relations, and discrete densities of states for Laplacian eigenvectors on complex networks

Per Arne Rikvold · 2026

To construct dispersion relations for diffusion or oscillation processes on random networks, it is necessary to obtain effective length scales for the eigenvectors of a graph Laplacian matrix, whose e…

The SK model with a sparse variance profile: free energy and AMP algorithm for TAP equations at high temperature

Walid Hachem · 2026

A generalization of the Sherrington-Kirkpatrick (SK) model for spin glasses is considered, in which the interaction matrix is endowed with a variance profile that has no particular structure an may be…

Influence of Heterogeneity on the Response of Architected Metamaterials

Sarvesh Joshi, Jingye Tan, Craig M. Hamel, Stavros Gaitanaros, Nikolaos Bouklas · 2026

Architected metamaterials like foams and lattices exhibit complex responses governed by microstructural instabilities, localization, and phase-transition-like phenomena. Their behavior is further affe…

Theory of Anderson localization on the hyperbolic plane

Alexander Altland, Tobias Micklitz, Devasheesh Sharma, Maksimilian Usoltcev, Carolin Wille · 2026

The two-dimensional hyperbolic plane, $\mathbb{H}^2$, is an unusual system in that dimensionality changes with scale: locally two-dimensional and planar at short distances, but effectively infinite-di…

Energetics of stochastic limit-cycle oscillators: when does coupling reduce dissipation?

Anton F. Burnet, Vansh Kharbanda, David Tobias, Benedikt Sabass · 2026

Non-linear oscillators serve important functions in many biological systems, including within the inner ear and neuronal networks. The sustainment of oscillations in noisy environments requires contin…

Bayesian phase transition for the critical Ising model: Enlarged replica symmetry in the epsilon expansion and in 2D

Kay Joerg Wiese, Alapan Das, Adam Nahum · 2026

A process that images or measures bond energies in the critical Ising model can be in distinct measurement ``phases'', depending on the precision of measurement. We study the transition into the stron…

Reshaping the inner shadow of a Kerr black hole by a torn accretion disk

Shiyang Hu, Dan Li, Chen Deng, Kejian He · 2026

When an accretion flow extends to the event horizon, their intersection defines the contour of the inner shadow. However, the morphological evolution of this critical feature remains largely unexplore…

Interplay of Flat-band and Anderson localizations in disordered moire superlattices

Qian Liu, Xiaoshuang Xia, Junjie Wang, Peilong Hong, Lei Xu, Lujun Huang, Daohong Song, Yi Liang · 2026

Disorder in moire superlattices simultaneously degrades flat-band localization and induces Anderson localization, yet how these two regimes interact has remained unclear. Here, we introduce a combined…
