Cats climb entails mammals move: preserving hyponymy in compositional distributional semantics
Gemma De las Cuevas, Andreas Klingler, Martha Lewis +1
To give vector-based representations of meaning more structure, one approach is to use positive semidefinite (psd) matrices. These allow us to model similarity of words as well as…
Separability for mixed states with operator Schmidt rank two
Gemma De las Cuevas, Tom Drescher, Tim Netzer
The operator Schmidt rank is the minimum number of terms required to express a state as a sum of elementary tensor factors. Here we provide a new proof of the fact that any biparti…
Energy as a detector of nonlocality of many-body spin systems
Jordi Tura, Gemma De las Cuevas, Remigiusz Augusiak +3
We present a method to show that low-energy states of quantum many-body interacting systems in one spatial dimension are nonlocal. We assign a Bell inequality to the Hamiltonian of…
Unifying all classical spin models in a Lattice Gauge Theory
G. De las Cuevas, W. Dür, H. J. Briegel +1
We show that the partition function of all classical spin models, including all discrete Standard Statistical Models and all abelian discrete Lattice Gauge Theories (LGTs), can be…
