The Sharp Rate of Probabilistically Strong Convergence to the KPZ Equation

Máté Gerencsér, Yueh-Sheng Hsu, Rhys Steele

One of the most common descriptions of solutions of singular SPDEs is their characterisation as the limit of solutions of renormalised smooth random PDEs. We quantify the speed of…

Variance renormalisation in regularity structures -- the case of $2 d$ gPAM

Máté Gerencsér, Yueh-Sheng Hsu

We consider the variance renormalisation of a singular SPDE for which a Da Prato-Debussche trick is not applicable. The example taken is the $2$ -dimensional generalised parabolic A…

Landau Hamiltonian with Gaussian white noise potential and the asymptotic of its bottom of spectrum

Yueh-Sheng Hsu

We present a simple construction of a random Schrödinger operator subject to a magnetic field with a regularity as low as $0^{-}$ -Hölder and a Gaussian white noise electric potential…

Construction and spectrum of the Anderson Hamiltonian with white noise potential on $R^{2}$ and $R^{3}$

Yueh-Sheng Hsu, Cyril Labbé

We propose a simple construction of the Anderson Hamiltonian with white noise potential on $R^{2}$ and $R^{3}$ based on the solution theory of the parabolic Anderson…
