Detecting emergent continuous symmetries at quantum criticality
Mingru Yang, Bram Vanhecke, Norbert Schuch
New or enlarged symmetries can emerge at the low-energy spectrum of a Hamiltonian that does not possess the symmetries, if the symmetry breaking terms in the Hamiltonian are irrele…

Simulating thermal density operators with cluster expansions and tensor networks
Bram Vanhecke, David Devoogdt, Frank Verstraete +1
We provide an efficient approximation for the exponential of a local operator in quantum spin systems using tensor-network representations of a cluster expansion. We benchmark this…
