Perturbative analysis of singularity-free cosmological solutions in unimodular Kaluza-Klein theory

J.C Fabris, S Faller, R Kerner

The unimodular version of the Kaluza-Klein theory is briefly recalled, and its projection on the $4$-dimensional spacetime is constructed. Imposing unimodularity condition on the $5$-dimensional Kaluza-Klein metric, det$g_{AB}=1$ is equivalent with introducing cosmological term in Einstein's…

The Wishart–Rosenzweig–Porter random matrix ensemble

Victor Delapalme, Leticia F Cugliandolo, Grégory Schehr, Marco Tarzia, Davide Venturelli

In recent years, the Rosenzweig–Porter (RP) ensemble, obtained by adding a diagonal matrix with independent and identically distributed elements to a Gaussian random matrix, has been widely used as a minimal model for the emergence of fractal eigenstates in complex many-body systems. A key open…

Critical Probability Distributions of the order parameter at two loops II: $O(n)$ universality class

Sankarshan Sahu

We show how to compute the probability distributions of the order parameter of the $O(n)$ model at two-loop order of perturbation theory generalizing the methods developed for computing the same in case of the Ising model \cite{Sahu:2025bkp}. We show that even for the $O(n)$ model, there exists not…

A Random Sequential Adsorption Model for the Prediction of SARS-CoV-2 Spike Protein Orientation and Distribution on a Sensing Surface

Vilius Vertelis, Julian Talbot, Vincentas Maciulis, Silvija Juciute, Ieva Plikusiene

The interaction between antibodies and viral proteins is crucial for immune response, and understanding these interactions is therefore of great importance. The sensitivity of immunosensors, where antigens are immobilized, largely depends on their orientation. However, experimental methods to…
