Mermin-Wagner theorems for quantum systems with multipole symmetries
Timo Feistl, Severin Schraven, Simone Warzel
We prove Mermin-Wagner-type theorems for quantum lattice systems in the presence of multipole symmetries. These theorems show that the presence of higher-order symmetries protects…

Fractional Quantum Hall States: Infinite Matrix Product Representation and its Implications
Severin Schraven, Simone Warzel
We present a novel matrix product representation of the Laughlin and related fractional quantum Hall wavefunctions based on a rigorous version of the correlators of a chiral quantu…

Local to global principle for higher moments over function fields
Andy Hsiao, Junhong Ma Blackmer, Severin Schraven +1
We establish a local to global principle for higher moments over holomorphy rings of global function fields and use it to compute the higher moments of rectangular unimodular matri…
