Universal terms of the entanglement entropy in a static closed universe
Rodolfo Soldati, L. S. Menicucci, N. Yokomizo
Subdominant contributions to the entanglement entropy of quantum fields include logarithmic corrections to the area law characterized by universal coefficients that are independent…
Linear growth of the entanglement entropy and the Kolmogorov-Sinai rate
Eugenio Bianchi, Lucas Hackl, Nelson Yokomizo
The rate of entropy production in a classical dynamical system is characterized by the Kolmogorov-Sinai entropy rate given by the sum of all positive Lyapunov exp…
Entanglement entropy of squeezed vacua on a lattice
Eugenio Bianchi, Lucas Hackl, Nelson Yokomizo
We derive a formula for the entanglement entropy of squeezed states on a lattice in terms of the complex structure J. The analysis involves the identification of squeezed states wi…
Dirac fermions in strong electric field and quantum transport in graphene
S. P. Gavrilov, D. M. Gitman, N. Yokomizo
Our previous results on the nonperturbative calculations of the mean current and of the energy-momentum tensor in QED with the T-constant electric field are generalized to arbitrar…
Localizability in de Sitter space
N. Yokomizo, J. C. A. Barata
An analogue of the Newton-Wigner position operator is defined for a massive neutral scalar field in de Sitter space. The one-particle subspace of the theory, consisting of positive…
Multiple classical limits in relativistic and nonrelativistic quantum mechanics
N. Yokomizo, J. C. A. Barata
The existence of a classical limit describing interacting particles in a second-quantized theory of identical particles with bosonic symmetry is proved. This limit exists in additi…
Topological low-temperature limit of Z(2) spin-gauge theory in three dimensions
N. Yokomizo, P. Teotonio-Sobrinho, J. C. A. Barata
We study Z(2) lattice gauge theory on triangulations of a compact 3-manifold. We reformulate the theory algebraically, describing it in terms of the structure constants of a bidime…
