Analysis of M=1 Modes in The EAST Tokamak
An analysis of precession fishbone, diamagnetic fishbone and internal kink mode in Tokamak plasmas is presented via solving the fishbone dispersion relation. Applying the dispersion relation to a typical EAST discharge, excitation of precession fishbone due to Neutral Beam Injection is successfully explained. The real frequency and growth rate of diamagnetic fishbone and internal kink mode are calculated, and the relevance of the diamagnetic branch is also discussed for the possible equilibrium…

pregnancy kink
One day I'll be brave enough to post my preg art and when that day comes I will have ascended into my ultimate freaky self.

Had a great time at the Leather Social at the Bodytalk bar in Utrecht yesterday! I went there with a friend of mine who is fairly new to the kink scene; he doesn't own any fetish gear, so I let him borrow my leather harness and black leather wrist wallets, while I wore my multicolored leather wrist wallets. We both went shirtless, and got a lot of attention from the other guys at the event! 😄

Horizontally Polarized Kink Oscillations Supported by Solar Coronal Loops in an Asymmetric Environment
Kink oscillations are ubiquitously observed in solar coronal loops, their understanding being crucial in the contexts of coronal seismology and atmospheric heating. We study kink modes supported by a straight coronal loop embeded in an asymmetric environment using three-dimensional magnetohydrodynamic (MHD) simulations. We implement the asymmetric effect by setting different exterior densities below and above the loop interior, and initiate the simulation using a kink-like velocity perturbation…

The Reflection Coefficient of a Reflectionless Kink
Classically, reflectionless kinks transmit all incident radiation. Recently, we have used an analyticity argument together with a solution of the Lippmann-Schwinger equation to write down the leading quantum correction to the reflection probability. The argument was fast but rather indirect. In the present paper, we calculate the reflection coefficient and probability by methodically grinding through the Schrodinger picture time evolution. We find the same answer. This answer contains contribut…

Revisiting kink-like parametrization and constraints using OHD/Pantheon+/BAO samples
We reexamine the kink-like parameterization of the deceleration parameter to derive constraints on the transition redshift from cosmic deceleration to acceleration. This is achieved using observational Hubble data, Type Ia Supernovae Pantheon+ samples and Baryon acoustic oscillations. In this parametrization, the value of the initial $q$ parameter is $q_{i}$, the final value is $q_f$, the present value is denoted by $q_{0}$, and the transition duration is given by $α$.

In-plane magnetic field driven conductance modulations in topological insulator kinks
We present low-temperature magnetoconductance measurements on Bi$_{1.5}$Sb$_{0.5}$Te$_{1.8}$Se$_{1.2}$ kinks with ribbon-shaped legs. The conductance displays a clear dependence on the in-plane magnetic field orientation. The conductance modulation is consistent with orbital effect-driven trapping of the topological surface states on different side facets of the legs of the kink, which affects their transmission across the kink. This magnetic field-driven trapping and conductance pattern can be…

🌊 An endless domino effect: Non-reciprocal topological solitons in active metamaterials
(... I studied nonlinear science for my PhD and took a while to understand that there were at least three things called "Solitons"; these ones are stabilized by topology as they represent a "kink" that won't go away)

An endless domino effect: Non-reciprocal topological solitons in active metamaterials
Topological solitons can be found in many places and at many different length scales. For example, they take the form of kinks in coiled telephone cords and large molecules such as proteins. At a very different scale, a black hole can be understood as a topological soliton in the fabric of spacetime. Solitons play an important role in biological systems, being relevant for protein folding and morphogenesis—the development of cells or organs.

Existence, uniqueness, and regularity of solutions to nonlinear and non-smooth parabolic obstacle problems
We establish the existence, uniqueness, and $W^{1,2,p}$-regularity of solutions to fully nonlinear parabolic obstacle problems when the obstacle is the pointwise supremum of arbitrary functions in $W^{1,2,p}$ and the operator is only assumed to be measurable in the state and time variables. The results hold for a large class of non-smooth obstacles, including all convex obstacles. Applied to stopping problems, they imply that the decision maker never stops at a convex kink of the stopping payof…

The Snake is a remarkable Galactic center radio filament with a morphology characterized by two kinks along its $\sim 20'$ extent. The major and minor kinks are located where the filament is most distorted from a linear magnetized structure running perpendicular to the Galactic plane. We present {\em Chandra}, VLA, and MeerKAT data and report the detection of an X-ray and radio source at the location of the major kink. High-resolution radio images of the major kink reveal a compact source with …

Horizontally and vertically polarized kink oscillations in curved solar coronal loops
Kink oscillations are frequently observed in coronal loops. This work aims to numerically clarify the influence of loop curvature on horizontally and vertically polarized kink oscillations. Working within the framework of ideal MHD, we conduct 3D simulations of axial fundamental kink oscillations in curved density-enhanced loops embedded in a potential magnetic field. Both horizontal and vertical polarizations are examined, and their oscillation frequencies are compared with WKB expectations. W…

Nuclear shape staggering of neutron-deficient Au and kink structure of Pb isotopes
In this study, we examine the abnormal odd-even shape staggering (OES) behavior of nuclear charge radii of neutron-deficient gold (Au) isotopes, which has recently been confirmed by advanced laser techniques. To understand the nuclear structure underlying this phenomenon, we apply the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc). Our results find that the shape staggering can be attributed to nuclear shape transition in the Au isotopes. The gold isotopic chain exhibits s…

Identifying Causal Effects under Kink Setting: Theory and Evidence
This paper develops a generalized framework for identifying causal impacts in a reduced-form manner under kinked settings when agents can manipulate their choices around the threshold. The causal estimation using a bunching framework was initially developed by Diamond and Persson (2017) under notched settings. Many empirical applications of bunching designs involve kinked settings. We propose a model-free causal estimator in kinked settings with sharp bunching and then extend to the scenarios w…

Nonlinear wave damping by Kelvin-Helmholtz instability induced turbulence
Magnetohydrodynamic kink waves naturally form as a consequence of perturbations to a structured medium, for example transverse oscillations of coronal loops. Linear theory has provided many insights in the evolution of linear oscillations, and results from these models are often applied to infer information about the solar corona from observed wave periods and damping times. However, simulations show that nonlinear kink waves can host the Kelvin-Helmholtz instability (KHi) which subsequently cr…

However, tubular biological structures are often pressurized, and the knowledge of the mechanical response upon bending in this scenario is limited. I…

There, magnetic reconnection, the drift-kink instability (DKI), and the flux-rope kink instability all compete and interact in their nonlinear stages to convert magnetic energy to plasma energy.

We compute the renormalized one-loop quantum corrections to the energy density $T_{00}(x)$ and pressure $T_{11}(x)$ for solitons in the $1+1$ dimensional scalar sine-Gordon and kink models. We show how precise implementation of counterterms in dimensional regularization resolves previously identified discrepancies between the integral of $T_{00}(x)$ and the known correction to the total energy.

Creation of Bound Half-Fermion Pairs by Solitons
In the presence of topologically nontrivial bosonic field configurations, the fermion number operator may take on fractional eigenvalues, because of the existence of zero-energy fermion modes. The simplest examples of this occur in 1+1 dimensions, with zero modes attached to kink-type solitons. In the presence of a kink-antikink pair, the two associated zero modes bifurcate into positive and negative energy levels with energies $\pm ge^{-gΔ}$, in terms of the Yukawa coupling $g\ll 1$ and the d…

Classically, the tension is $m^3/3λ$ where $λ$ is the coupling and $m$ is the meson mass. At order $O(λ^0)$ all ultraviolet divergences can be removed by normal ordering, less trivial divergences arrive only at the next order. This allows us to easily quantize the domain wall, working at order $O(λ^0)$. We calculate the leading quantum corr…

Using Bright-Point Shapes to Constrain Wave-Heating of the Solar Corona: Predictions for DKIST
Magnetic bright points on the solar photosphere mark the footpoints of kilogauss magnetic flux tubes extending toward the corona. Convective buffeting of these tubes is believed to excite magnetohydrodynamic waves, which can propagate to the corona and there deposit heat. Measuring wave excitation via bright-point motion can thus constrain coronal and heliospheric models, and this has been done extensively with centroid tracking, which can estimate kink-mode wave excitation.

Amplitude modulations and resonant decay of excited oscillons
We show that the decay of strongly excited oscillons in a single vacuum model reveals a chaotic, fractal-like pattern very much like one found in kink-antikink collision in the $ϕ^4$ model. This structure can be attributed to the resonant energy transfer mechanism triggered by the modulations of amplitudes of constituent oscillons which form the excited oscillon. We also find evidence that such modulations arise as a motion of two quasi-breathers inside the constituent oscillon.
