Tensor renormalization group approach to entanglement entropy

Journal of High Energy Physics
We propose a method to compute the entanglement entropy (EE) using the tensor renormalization group (TRG) method. The reduced density matrix of a d-dimensional quantum system is represented as a (d + 1)-dimensional tensor network.

THE DEVELOPMENT OF PURE-SYSTOLIC ALGORITHM FOR COMPUTING NUMBER-THEORETIC TRANSFORMS OF SIGNALS

Современная наука и инновации, 2022
The search for new ways to improve the efficiency of digital signal processing has led to the intensification of the deconveyor methods of calculations implemented on the basis of pure systolic matrices allows to increase the speed of the theoretical and numerical transformations of signals.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Prospects for a lattice calculation of the rare decay Σ+ → pℓ + ℓ −

Journal of High Energy Physics, 2023
We present a strategy for calculating the rare decay of a Σ+(uus) baryon to a proton (uud) and di-lepton pair using lattice QCD. To determine this observable one needs to numerically evaluate baryonic two-, three-, and four-point correlation functions ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Lattice gradient flows (de-)stabilizing topological sectors

Journal of High Energy Physics
We investigate the stability of topological charge under gradient flow taking the admissibility condition into account. For the SU(2) Wilson gauge theory with β = 2.45 and L 4 = 124, we numerically show that the gradient flows with the Iwasaki and DBW2 ...
