Vortex Dynamics Using Molecular Dynamics with Heat Transport and Retarded Vortex-vortex Interaction

Physics Procedia, 2013
AbstractUsing the molecular dynamics method, we investigate vortex dynamics in a Crobino superconducting disk under an external field. In order to incorporate non-uniform heat generations due to motions of vortices in a Crobino disk and a retarded vortex-vortex interaction due to quasi-particle relaxations, we extend the molecular dynamics method ...

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures

Advanced Functional Materials, EarlyView.
3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

The Antarctic stratospheric nitrogen hole: Southern Hemisphere and Antarctic springtime total nitrogen dioxide and total ozone variability as observed by Sentinel-5p TROPOMI [PDF]

Atmospheric Chemistry and Physics
Denitrification within the stratospheric vortex is a crucial process for Antarctic ozone hole formation, resulting in an analogous stratospheric “nitrogen hole”.

The effect of convergent-divergent tube on the cooling capacity of vortex tube: An experimental and numerical study

Alexandria Engineering Journal, 2020
In this investigation, experimental and computational fluid dynamics (CFD) technique is used to study a newly designed Ranque-Hilsch vortex tube (RHVT), such as a convergent-divergent one.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Vortex lines or sheets - what is formed in dynamic drives?

, 2001
In isotropic macroscopic quantum systems vortex lines can be formed while in anisotropic systems also vortex sheets are possible. Based on measurements of superfluid 3He-A, we present the principles which select between these two competing forms of ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Dark photon vortex formation and dynamics

Journal of High Energy Physics, 2022
We study the formation and evolution of vortices in U(1) dark photon dark matter and dark photon clouds that arise through black hole superradiance. We show how the production of both longitudinal mode and transverse mode dark photon dark matter can lead

Dynamics of Few Co-rotating Vortices in Bose-Einstein Condensates

, 2013
We study the dynamics of small vortex clusters with few (2--4) co-rotating vortices in Bose-Einstein condensates by means of experiments, numerical computations, and theoretical analysis. All of these approaches corroborate the counter-intuitive presence
