Global and short-range entanglement properties in excited, many-body localized spin chains
Colin G. West, Tzu-Chieh Wei
We explore the use of short-range entanglement measures, such as concurrence and negativity, and global entanglement measures such as geometric entanglement, as indicators of many-…

Detection of gapped phases of a 1D spin chain with onsite and spatial symmetries
Abhishodh Prakash, Colin G. West, Tzu-Chieh Wei
We investigate the phase diagram of a quantum spin-1 chain whose Hamiltonian is invariant under a global onsite , translation and lattice inversion symmetries. We detect diffe…

Efficient evaluation of high-order moments and cumulants in tensor network states
Colin West, Artur Garcia-Saez, Tzu-Chieh Wei
We present a numerical scheme for efficiently extracting the higher-order moments and cumulants of various operators on spin systems represented as tensor product states, for both…
