Codimension in planar polynomial differential systems

Electronic Journal of Differential Equations
The topological classification of large families of polynomial differential systems remains an extremely difficult problem. Even for the simplest nonlinear case, the quadratic systems, this problem is still open.

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

DK/Dπ scattering and an exotic virtual bound state at the SU(3) flavour symmetric point from lattice QCD

Journal of High Energy Physics
Elastic S-wave scattering of a charm meson with a light pseudoscalar meson in J P = 0+ is investigated in the flavour 3 ¯ $$ \overline{\textbf{3}} $$ , 6 and 15 ¯ $$ \overline{\textbf{15}} $$ sectors at the SU(3) f flavour point using lattice QCD ...

Complex Riemannian Spacetime: Removal of Black Hole Singularities and Black Hole Paradoxes

Axioms
An approach is presented to resolve key paradoxes in black hole physics through the application of complex Riemannian spacetime. We extend the Schwarzschild metric into the complex domain, employing contour integration techniques to remove singularities ...

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

Methodological Fundamentalism: or why Batterman’s Different Notions of ‘Fundamentalism’ may not make a Difference [PDF]

, 2006
I argue that the distinctions Robert Batterman (2004) presents between ‘epistemically fundamental’ versus ‘ontologically fundamental’ theoretical approaches can be subsumed by methodologically fundamental procedures.

ZFL-FEL: Resolving Singularities and Infinity via Geometric Theory of Finite Accumulation of Infinite Loss (FAIL)

ZFL–FEL (Zero-closure Linear Flow – False Escape Loop) is a phenomenological framework that reinterprets time, cosmic expansion, and material stability through the lens of asymptotic resolution refinement rather than fundamental spacetime dynamics.   Instead of treating time as an independent dimension or universal expansion as a literal stretching ...

Sub‐Nanometer Curvature Unlocks Quantum Orbital Flexoelectricity in Graphene

Advanced Materials, EarlyView.
In self‐assembled, reproducible, large‐area, quasi‐pristine graphene nanowrinkles, extreme curvature forces out‐of‐plane π‐electrons toward hybridization, driving a transition from classical to quantum orbital flexoelectricity. As curvature approaches the fundamental physical limit set by the C─C bond length, the resulting polarization increases by ...

Resolving singularities in gravitational and electrostatic interactions through spatial quantization

Science Progress
Classical physics assumes continuous spacetime, leading to infinities in forces (e.g., Newtonian gravity, electrostatic force) at zero distance or relativistic energy for objects with non-zero mass at the speed of light.
