High-order series expansion of non-Hermitian quantum spin models
L. Lenke, M. Mühlhauser, K. P. Schmidt
We investigate the low-energy physics of non-Hermitian quantum spin models with -symmetry. To this end we consider the one-dimensional Ising chain and the two-dimensional toric…

Competing topological orders in three dimensions: X-cube versus toric code
M. Mühlhauser, K. P. Schmidt, J. Vidal +1
We study the competition between two different topological orders in three dimensions by considering the X-cube model and the three-dimensional toric code. The corresponding Hamilt…
