Published in 2019 at "Annalen der Physik"

DOI: 10.1002/andp.201800461

Abstract: Normal‐mode splitting (NMS) is one of the most significant manifestations of strongly coupled systems. Here, NMS is shown to occur in a weakly coupled electromechanical system. In this system, an exponentially enhanced electromechanical coupling is… read more here.

DOI: 10.1002/mma.10204

Abstract: In this work, we consider the efficient resolution of a 2D elliptic singularly perturbed weakly coupled system of convection–diffusion type, which has small parameters at both the diffusion and the convection terms. We assume that… read more here.

DOI: 10.1007/jhep07(2019)107

Abstract: A bstractWe study the contour dependence of the out-of-time-ordered correlation function (OTOC) both in weakly coupled field theory and in the Sachdev-Ye-Kitaev (SYK) model. We show that its value, including its Lyapunov spectrum, depends sensitively… read more here.

Published in 2017 at "International Journal of Solids and Structures"

DOI: 10.1016/j.ijsolstr.2017.09.010

Abstract: Abstract A 3D peridynamic formulation of the thermo-mechanical problem allows to efficiently simulate the occurrence and propagation of cracks due to extreme thermal loading. The model is weakly coupled since no internal heat generation due… read more here.
