Irreducible forms of Matrix Product States: Theory and Applications
Gemma De las Cuevas, J. Ignacio Cirac, Norbert Schuch +1
The canonical form of Matrix Product States (MPS) and the associated fundamental theorem, which relates different MPS representations of a state, are the theoretical framework unde…
Efficient Basis Formulation for (1+1)-Dimensional SU(2) Lattice Gauge Theory: Spectral calculations with matrix product states
Mari Carmen Bañuls, Krzysztof Cichy, J. Ignacio Cirac +2
We propose an explicit formulation of the physical subspace for a (1+1)-dimensional SU(2) lattice gauge theory, where the gauge degrees of freedom are integrated out. Our formulati…
Correlation decay in fermionic lattice systems with power-law interactions at non-zero temperature
Senaida Hernández-Santana, Christian Gogolin, J. Ignacio Cirac +1
We study correlations in fermionic lattice systems with long-range interactions in thermal equilibrium. We prove a bound on the correlation decay between anti-commuting operators a…
