On a wave equation with singular dissipation
Mohammed ElAmine Sebih, Jens Wirth
In this paper we consider a singular wave equation with distributional and more singular non-distributional coefficients and develop tools and techniques for the phase-space analys…
Decay estimates for a Klein-Gordon model with time-periodic coefficients
Giovanni Girardi, Jens Wirth
In this paper we consider a Klein-Gordon model with time-dependent periodic coefficients. The aim is to investigate how the presence of the mass term influences energy estimates wi…
Gelfand triples for the Kohn-Nirenberg quantization on homogeneous Lie groups
Jonas Brinker, Jens Wirth
In this paper, we study the group Fourier transform and the Kohn-Nirenberg quantization for homogeneous Lie groups as mappings between certain Gelfand triples. For this, we restric…
Zero resonances for localised potentials
Vladimir Georgiev, Jens Wirth
This paper considers Hamiltonians with localised potentials and gives a variational characterisation of resonant coupling parameters, which allow to provide estimates for the first…
On t-dependent hyperbolic systems. Part 2
Jens Wirth
We consider hyperbolic equations with time-dependent coefficients and develop an abstract framework to derive the asymptotic behaviour of the representation of solutions for large…
Physical and mathematical justification of the numerical Brillouin zone integration of the Boltzmann rate equation by Gaussian smearing
Christian Illg, Michael Haag, Nicolas Teeny +2
Scatterings of electrons at quasiparticles or photons are very important for many topics in solid state physics, e.g., spintronics, magnonics or photonics, and therefore a correct…
