    • Conformal data from finite entanglement scaling 

      Stojevic, Vid; Haegeman, Jutho; McCulloch, I. P.; Tagliacozzo, Luca; Verstraete, Frank (APS Physics, 2015-01-20)
      Article
      Accés obert
      In this paper, we apply the formalism of translation invariant (continuous) matrix product states in the thermodynamic limit to (1 + 1)-dimensional critical models. Finite bond dimension bounds the entanglement entropy ...

    • Locality of temperature in spin chains 

      Hernández-Santana, Senaida; Riera, Arnau; Hovhannisyan, Karen V.; Perarnau-Llobet, Martí; Tagliacozzo, Luca (IOP, 2015-08-18)
      Article
      Accés obert
      In traditional thermodynamics, temperature is a local quantity: a subsystem of a large thermal system is in a thermal state at the same temperature as the original system. For strongly interacting systems, however, the ...

    • Tensor Networks for Lattice Gauge Theories with continuous groups 

      Tagliacozzo, Luca; Celi, Alessio; Lewenstein, Maciej (ACS Publications, 2014-11-06)
      Article
      Accés obert
      We discuss how to formulate lattice gauge theories in the tensor-network language. In this way, we obtain both a consistent-truncation scheme of the Kogut-Susskind lattice gauge theories and a tensornetwork variational ...

    • Terahertz field control of in-plane orbital order in La0.5Sr1.5MnO4 

      Miller, Timothy A.; Chhajlany, Ravindra W.; Tagliacozzo, Luca; Green, Bertram; Kovalev, Sergey; Prabhakaran, Dharmalingam; Lewenstein, Maciej; Gensch, Michael; Wall, Simon (Nature Publishing Group, 2015-09-18)
      Article
      Accés obert
      In-plane anisotropic ground states are ubiquitous in correlated solids such as pnictides, cuprates and manganites. They can arise from doping Mott insulators and compete with phases such as superconductivity; however, their ...
