Quantum Depletion of Superconductivity in 3D Diamond Nanowires
Advanced Quantum Technologies, EarlyView.Heavily boron‐doped polycrystalline diamond nanowires demonstrate an exotic resistive state that alters the trend of the superconducting transition. This reentrant resistive state manifests itself as a peak in the current dependence of voltage and a negative magnetoresistance peak. This suggests that cross‐sectional grain boundaries can promote quantum‐

arXiv, 2015 The American Physical Society (APS) March Meeting of condensed matter physics has grown to nearly 10,000 participants, comprises 23 individual APS groups, and even warrants its own hashtag (#apsmarch). Here we analyze the text and data from March Meeting abstracts of the past nine years and discuss trends in condensed matter physics over this time ...

Spinor condensates and light scattering from Bose-Einstein condensates [PDF]
, 2000 These notes discuss two aspects of the physics of atomic Bose-Einstein condensates: optical properties and spinor condensates. The first topic includes light scattering experiments which probe the excitations of a condensate in both the free-particle and phonon regime.

Evolution of Dissipative Regimes in Atomically Thin Bi2Sr2CaCu2O8 + x Superconductor
Advanced Electronic Materials, Volume 11, Issue 4, April 2025.The combination of cryogenic exfoliation methods with a new generation of thermoelectric chips based on silicon nitride microprinted circuit boards gives access to the vortex‐dissipation regime in atomically thin Bi2Sr2CaCu2O8 + x superconductor. The investigation of the Nernst signal in nanostructured samples demonstrates that finite‐size effects play

A Field Guide to Non‐Onsager Quantum Oscillations in Metals
Advanced Physics Research, Volume 4, Issue 4, April 2025.The observation of quantum oscillations is usually taken as strong evidence for the existence of a Fermi surface according to the famous Onsager relation. The article reviews mechanisms that generate quantum oscillation frequencies that defy the Onsager relation where special emphasis is put on the recently discovered quasi‐particle lifetime ...

Unveiling Electron‐Phonon and Electron‐Magnon Interactions in the Weak Itinerant Ferromagnet LaCo2P2
Advanced Physics Research, Volume 4, Issue 4, April 2025.Electron‐boson interactions in the weak itinerant ferromagnet LaCo2P2 are investigated, addressing both surface and bulk properties. The intricate renormalization of electronic states due to electron‐phonon and electron‐magnon interactions is examined, highlighting their distinct impacts on the electronic structure.
