Here, using comprehensive first-principles… Theory Ca₂N https://arxiv.org/abs/2608.29833v1 https://arxiv.org/abs/2608.29833v1 Sun, 30 Aug 2026 15:03:05 GMT arXiv: The recent discovery of long-sought dice flat band in layered YCl electride has opened up rich possibilities of correlation and topological physics in dice lattice systems [Nature Communications 17, 2213 (2026), arXiv:2509.05958]. Here, we reveal a plethora of distinctive correlated topological phases in a generic… Theory Ca₂N https://arxiv.org/abs/2608.07856v1 https://arxiv.org/abs/2608.07856v1 Sat, 08 Aug 2026 01:51:52 GMT arXiv: Electrides are an unusual class of ionic materials in which electrons localized in non-nuclear, interstitial regions act as anions within the crystal lattice. Here, we employ first-principles quantum mechanical calculations to investigate the structural, electronic, magnetic, and electride characteristics of elemental… Theory Ca₂N https://arxiv.org/abs/2607.10024v1 https://arxiv.org/abs/2607.10024v1 Fri, 10 Jul 2026 23:04:43 GMT arXiv: We investigate the magnetic-field response of interstitial anionic electrons (IAEs) in two-dimensional electrides, using monolayer Ca₂N as a prototypical system. By computing the Landau-level (LL) spectrum of the electride bands forming the Fermi surface, we find a linear LL evolution with magnetic field that closely… Theory Ca₂N https://arxiv.org/abs/2605.31195v1 https://arxiv.org/abs/2605.31195v1 Fri, 29 May 2026 12:03:01 GMT arXiv: Electron transport in solids arises primarily from two mechanisms: freely moving bulk electrons in metals, and gapless boundary states in topological insulators. Here, we report a new mechanism discovered in electrides. The topological interstitial-electron conductors (TIECs) proposed here are insulating electrides… Theory Ca₂N https://arxiv.org/abs/2603.26404v1 https://arxiv.org/abs/2603.26404v1 Fri, 27 Mar 2026 13:27:08 GMT arXiv: Altermagnetism has so far been associated with compensated magnetic moments carried by atoms. Here we introduce Stoner instability induced interstitial-electron altermagnetism, a distinct mechanism in which altermagnetic order is carried instead by interstitial anionic electrons in electrides. We show that, owing to… Theory Ca₂N
