Most two-dimensional bosonic topological orders forbid sign-problem-free quantum Monte Carlo: Nonpositive Gauss sum as an indicator
Donghae Seo, Minyoung You, Hee-Cheol Kim +1
Quantum Monte Carlo is a powerful tool for studying quantum many-body physics, yet its efficacy is often curtailed by the notorious sign problem. In this Letter, we introduce a nov…

Modular extension of topological orders from congruence representations
Donghae Seo, Minyoung You, Gil Young Cho +1
We present an efficient method to compute the modular extension of both fermionic topological orders and -symmetric bosonic topological orders in two spatial dimensio…

Gapped boundaries of fermionic topological orders and higher central charges
Minyoung You
We develop a test for the vanishing of higher central charges of a fermionic topological order, which is a necessary condition for the existence of a gapped boundary, purely in ter…
