On monoids up to symmetry
Dinh Van Le, Tim Römer, Nguyen Thi Vien
We study monoids in an infinite-dimensional setting that are invariant under the action of the infinite symmetric group Sym. Our main result establishes a local--global principle c…
Resonant level model from a Krylov perspective: Lanczos coefficients in a quadratic model
Merlin Füllgraf, Jiaozi Wang, Jochen Gemmer +1
We study the Lanczos coefficients in a quadratic model given by an impurity interacting with a multi-mode field of fermions, also known as resonant level model. We analytically der…
Scaling of free cumulants in closed system-bath setups
Merlin Füllgraf, Jochen Gemmer, Jiaozi Wang
The Eigenstate Thermalization Hypothesis (ETH) has been established as a cornerstone for understanding thermalization in quantum many-body systems. Recently, there has been growing…
Theory for the mixed alkali effect in glasses
Justus Leiber, Quinn Emilia Fischer, Sven Lohmann +1
The mixed alkali or mixed mobile ion effect in glasses manifests itself by strong nonlinear variations of ionic transport properties upon mixing of different types of mobile ions.…
