Inviscid damping and enhanced dissipation of the boundary layer for 2D Navier-Stokes linearized around Couette flow in a channel

We study the 2D Navier-Stokes equations linearized around the Couette flow $(y,0)^t$ in the periodic channel $\mathbb T \times [-1,1]$ with no-slip boundary conditions in the vanishing viscosity $\nu \to 0$ limit. Expand abstract.

Non-Bloch $\mathcal{PT}$ symmetry breaking in non-Hermitian Photonic Quantum Walks

A hallmark of topological band theory in periodic media is that bulk properties are not affected by boundary conditions. Expand abstract.

Finite element modeling of micropolar-based phononic crystals

The periodic boundary conditions are given for both translational and rotational degrees of freedom and for the associated force- and couple-traction vectors. Expand abstract.

Infrared renormalon in $SU(N)$ QCD(adj.) on $\mathbb{R}^3\times S^1$

We study the infrared (IR) renormalon ambiguity in the gluon condensate in the $SU(N)$ gauge theory with $n_W$-flavor adjoint fermions (QCD(adj.)) on~$\mathbb{R}^3\times S^1$ with the $\mathbb{Z}_N$ twisted boundary conditions. Expand abstract.

Analysis of switching strategies for the optimization of periodic chemical reactions with controlled flow-rate

We exploit the Chen-Fliess functional expansion of solutions to the considered nonlinear system with bang-bang controls to satisfy the boundary conditions and evaluate the cost analytically for small periods. Expand abstract.

Parabolic equations with dynamic boundary conditions and drift terms

The aim of this paper is to study the wellposedness and $L^2$-regularity, firstly for a linear heat equation with dynamic boundary conditions by using the approach of sesquilinear forms, and secondly for its backward adjoint equation using the Galerkin approximation and the extension semigroup to a negative Sobolev space.
