Disorder-free localization in a simple U(1) lattice gauge theory (2020)
Journal Article
Papaefstathiou, I., Smith, A., & Knolle, J. (2020). Disorder-free localization in a simple U(1) lattice gauge theory. Physical Review B, 102(16), Article 165132. https://doi.org/10.1103/physrevb.102.165132

Localization due to the presence of disorder has proven crucial for our current understanding of relaxation in isolated quantum systems. The many-body localized phase constitutes a robust alternative to the thermalization of complex interacting syste... Read More about Disorder-free localization in a simple U(1) lattice gauge theory.

Intrinsic sign problem in fermionic and bosonic chiral topological matter (2020)
Journal Article
Golan, O., Smith, A., & Ringel, Z. (2020). Intrinsic sign problem in fermionic and bosonic chiral topological matter. Physical Review Research, 2(4), Article 043032. https://doi.org/10.1103/physrevresearch.2.043032

The infamous sign problem leads to an exponential complexity in Monte Carlo simulations of generic many-body quantum systems. Nevertheless, many phases of matter are known to admit a sign-problem-free representative, allowing efficient simulations on...

The sign problem is a widespread numerical hurdle preventing us from simulating the equilibrium behavior of various problems at the forefront of physics. Focusing on an important subclass of such problems, bosonic (2+1)-dimensional topological quantu... Read More about Intrinsic sign problems in topological quantum field theories.
