Even spin N = 4 $$ \mathcal{N}=4 $$ holography

Journal of High Energy Physics, 2017
A two-dimensional Sp(2N ) vector model with small N = 4 $$ \mathcal{N}=4 $$ superconformal symmetry is formulated, and its chiral algebra is shown to be freely generated by super-primary fields of even conformal weight.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Rigidity of Weak Einstein-Randers Spaces [PDF]

Sahand Communications in Mathematical Analysis
The Randers metrics are popular metrics similar to the Riemannian metrics, frequently used in physical and geometric studies. The weak Einstein-Finsler metrics are a natural generalization of the Einstein-Finsler metrics.

2-conformal and conformal vector fields on Riemannian manifolds

Filomat
In this paper, we study 2-conformal vector fields on Riemannian manifolds. Some relations between 2-conformal vector fields, conformal vector fields, Killing and 2-Killing vector fields have been obtained. Also, relation between monotone vector fields and 2-conformal vector fields is investigated.
