Recent progress of the exchange bias based on 2D van der Waals ferromagnet
InfoScience, EarlyView.Ultrathin magnetic materials could help make smaller, energy‐efficient memories, but their magnetic states must remain stable and controllable. This review brings together recent research on exchange bias, a magnetic pinning effect in layered materials, and explains how interfaces and electrical, thermal or mechanical controls can tune it, with optical

Heisenberg idempotents on unipotent groups [PDF]
Mathematical Research Letters, 2010 Let G be an algebraic group over an algebraically closed field of positive characteristic such that its neutral connected component is a unipotent group. We consider a certain class of closed idempotents in the braided monoidal category (under convolution of complexes) D_G(G) known as Heisenberg idempotents.

Critical Homogeneous Metrics on the Heisenberg Manifold [PDF]
, 2010 application/pdfLet H be the Heisenberg group and let Γ be the discrete subgroup of H with integer entries. We obtain a necessary and sufficient condition for a homogeneous metric g on H/Γ to be a critical point for the total scalar curvature functional I

Parallel Multi‐Target Detection for Quantum LiDAR
Laser &Photonics Reviews, EarlyView.Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

Triangles in the Heisenberg Group [PDF]
, 2010 In the Heisenberg Lie group with the Carnot-Caratheodory metric, we classify geodesic triangles up to isometry in terms of side-length and geodesic parameters. We obtain an angle deficit formula for Heisenberg triangles.

Translation of: W. Heisenberg, ‘Ist eine deterministische Ergänzung der Quantenmechanik möglich?’ [PDF]
The publication of the EPR paper in 1935 prompted Heisenberg to draft a manuscript on the question of the completability of quantum mechanics (which was published only posthumously).

Purely Coclosed G2‐Structures on Nilmanifolds—II
Mathematische Nachrichten, EarlyView.ABSTRACT This paper completes the classification of seven‐dimensional nilpotent Lie groups endowed with a left‐invariant purely coclosed G2$\text{G}_2$‐structure, initiated in Bazzoni et al. [Mathematische Nachrichten 296 no. 6 (2023): 2236–2257], the authors provided the classification of decomposable seven‐dimensional nilpotent Lie groups and of the ...

A Boothby–Wang Construction in Generalized Contact Geometry
Mathematische Nachrichten, EarlyView.ABSTRACT We establish a generalized analogue of the Boothby–Wang theorem in generalized contact geometry, along with related results. We present a general method for constructing examples of generalized contact structures that are not of Poon–Wade type, and even examples that fail to be generalized contact structures.

Non-local elliptic systems on the Heisenberg group
Electronic Journal of Differential Equations, 2016 We present Liouville type results for certain systems of nonlinear elliptic equations containing fractional powers of the Laplacian on the Heisenberg group.

On Geometric Phase Model in the Theory of Curves With Myller Configuration
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this paper, we introduce a linearly polarized light wave in an optical fiber and rotation of the polarization plane through the Frenet‐type frame with Myller configuration. Since the geometric evaluation and interpretations of a polarized light wave are associated with geometric phase, a new type of geometric phase model has been ...
