Ultra-slow dynamics in a translationally invariant spin model for multiplication and factorization
Lei Zhang, Stefanos Kourtis, Claudio Chamon +2
We construct a model of short-range interacting Ising spins on a translationally invariant two-dimensional lattice that mimics a reversible circuit that multiplies or factorizes in…
Observing spin fractionalization in the Kitaev spin liquid via temperature evolution of indirect resonant inelastic x-ray scattering
Gábor B. Halász, Stefanos Kourtis, Johannes Knolle +1
Motivated by the ongoing effort to search for high-resolution signatures of quantum spin liquids, we investigate the temperature dependence of the indirect resonant inelastic x-ray…
Quantum spin liquid at finite temperature: proximate dynamics and persistent typicality
I. Rousochatzakis, S. Kourtis, J. Knolle +2
Quantum spin liquids are long-range entangled states of matter with emergent gauge fields and fractionalized excitations. While candidate materials, such as the Kitaev honeycomb ru…
Evaluating the Jones polynomial with tensor networks
Konstantinos Meichanetzidis, Stefanos Kourtis
We introduce tensor network contraction algorithms for the evaluation of the Jones polynomial of arbitrary knots. The value of the Jones polynomial of a knot maps to the partition…
Fast counting with tensor networks
Stefanos Kourtis, Claudio Chamon, Eduardo R. Mucciolo +1
We introduce tensor network contraction algorithms for counting satisfying assignments of constraint satisfaction problems (#CSPs). We represent each arbitrary #CSP formula as a te…
Scrambling via Braiding of Nonabelions
Zhi-Cheng Yang, Konstantinos Meichanetzidis, Stefanos Kourtis +1
We study how quantum states are scrambled via braiding in systems of non-Abelian anyons through the lens of entanglement spectrum statistics. In particular, we focus on the degree…
