Logarithmic negativity of the 1D antiferromagnetic spin-1 Heisenberg model with single-ion anisotropy
Vladimir V. Papoyan, Giacomo Gori, Andrea Trombettoni +1
We study the 1D antiferromagnetic spin-1 Heisenberg XXX model with external magnetic field B and single-ion anisotropy D on finite chains. We determine the nearest and non-nearest…

Complex scaling flows in the quench dynamics of interacting particles
Tilman Enss, Noel Cuadra Braatz, Giacomo Gori
Many-body systems driven out of equilibrium can exhibit scaling flows of the quantum state. For a sudden quench to resonant interactions between particles we construct a new class…
