Abstract
In this study, we explore the behavior of a superconducting meso-wedge geometry in 3+1 dimensions (three spatial dimensions plus time) subjected to transport currents at its boundaries and surfaces, as well as external fields applied along the $\hat{z}$-direction. The transport currents are included as two opposite polarities, $\textbf{J}>0$ and $\textbf{J}<0$. Using the generalized time-dependent Ginzburg-Landau theory and taking into account $\kappa$, we focus on two distinct scenarios: (i) constant external magnetic field with variable $\kappa$, and (ii) constant $\kappa$ with variable external magnetic field. As a result, under both scenarios, we analyze the voltage-current characteristics of the superconducting meso-wedge, finding that the critical currents differ between polarities, demonstrating the system's non-reciprocity. We further examine the efficiency of the diode as a function of $\kappa$ and the external magnetic field applied. Furthermore, our observations reveal that the current polarity strongly influences the vortex configuration, the parameter $\kappa$, and the applied magnetic field. In particular, the formation of Abrikosov-type vortices exhibits pronounced inhomogeneity depending on the direction of the transport currents. This underscores that the diode effect in the superconducting meso-wedge is intimately associated with the anisotropic nucleation of Abrikosov vortices. Notably, the emergence of polarity-dependent vortex patterns can serve as a distinctive hallmark of the diode effect in these superconducting systems.
Author comments upon resubmission
Dear Editor,
We thank you for the opportunity to resubmit our manuscript entitled "Superconducting diode effect in a meso-wedge geometry with Abrikosov vortices" (manuscript scipost_202505_00028v1) for consideration in SciPost Physics Core.
In preparing this revised version, we have not only incorporated new content to strengthen the scientific scope of the work but also carefully revised the entire manuscript to enhance its clarity, coherence, and overall readability. All comments and suggestions provided by the referee have been addressed in detail, and we have made substantial efforts to clarify the motivation, methodology, and significance of our results.
We believe that these improvements, together with the additional material included, have considerably strengthened the manuscript. We are therefore confident that the revised version now meets the high standards of SciPost Physics Core, and we are pleased to resubmit it for your kind consideration.
Thank you for your consideration and we look forward to hearing from you.
Sincerely,
J. Faundez, on behalf of the authors.

Report
Second report on "Superconducting diode effect in a meso-wedge geometry with Abrikosov vortices" by C. A. Aguirre , J. Barba-Ortega , A. S. de Arruda and J. Faundez.
The authors responded appropriately to most of my comments and think the manuscript has considerably improved. For these reasons I recommend the acceptance of the manuscript.
I would like to note that some of my previous comments, although responded, were not implemented in the manuscript. I believe that such comments are not critical but they can help improve further the manuscript.
-
In my previous question Q5, I asked the authors to write down their findings in the last paragraph of the introduction. However, they did not address it. Although this is not critical, I think it is useful to discuss the findings in the suggested paragraph, not just mentioning the goals of the work.
-
I advise the authors to add in their manuscript the explanation that they wrote in their previous response to Q8, all in relation to the discussion of Fig.2.
-
The same advice as in point 2 above applies for Fig.3 and their response to my previous question Q9.
-
The response given to my comment Q10 would be good to be implemented in the manuscript as well. Discussing how to achieve higher efficiencies would also improve the manuscript.
