Nonrelativistic spinning strings

Journal of High Energy Physics, 2020
We construct nonrelativistic spinning string solutions corresponding to SU(1, 2|3) Spin-Matrix theory (SMT) limit of strings in AdS 5 × S 5. Considering various nonrelativistic spinning string configurations both in AdS 5 as well as S 5 we obtain ...

Threshold corrections and symmetry enhancement in string compactifications [PDF]

Nuclear Physics B, 1995
We present the computation of threshold functions for Abelian orbifold compactifications. Specifically, starting from the massive, moduli-dependent string spectrum after compactification, we derive the threshold functions as target space duality invariant free energies (sum over massive string states).

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe

Advanced Functional Materials, EarlyView.
By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Kerr-Newman black holes with string corrections [PDF]

Journal of High Energy Physics, 2016
We study $\mathcal{N}=2$ supergravity with higher-derivative corrections that preserve the $\mathcal{N}=2$ supersymmetry and show that Kerr-Newman black holes are solutions to these theories. Modifications of the black hole entropy due to the higher derivatives are universal and apply even in the BPS and Schwarzschild limits.

Aspects of Topological String Theory [PDF]

, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Role of density inhomogeneity in dissipative collapse through Finch-Skea spacetime in f(R) gravity

Nuclear Physics B
This study investigates the dynamics of dissipative gravitational collapse within the framework of f(R) gravity, focusing on the exponential correction model f(R)=R−β1Rs(1−e−R/Rs) and incorporating the concept of a horizon function. The model considers a
