Tensor-network approach to phase transitions in string-net models
Alexis Schotte, Jose Carrasco, Bram Vanhecke +4
We use a recently proposed class of tensor-network states to study phase transitions in string-net models. These states encode the genuine features of the string-net condensate suc…
New computable entanglement monotones from formal group theory
José A. Carrasco, Giuseppe Marmo, Piergiulio Tempesta
We present a mathematical construction of new quantum information measures that generalize the notion of logarithmic negativity. Our approach is based on formal group theory. We sh…
Supersymmetric - models with long-range interactions: thermodynamics and criticality
B. Basu-Mallick, N. Bondyopadhaya, J. A. Carrasco +2
We analyze the thermodynamics and the critical behavior of the supersymmetric su() - model with long-range interactions. Using the transfer matrix formalism, we obtain a c…
Formal Rings
José Carrasco, Piergiulio Tempesta
A notion of one-dimensional formal ring is presented. It consists of a triple where is a unital ring and and are two formal power series in variables ${Φ(…
