Irreversible processes without energy dissipation in an isolated Lipkin-Meshkov-Glick model.
For a certain class of isolated quantum systems, we report the existence of irreversible processes in which the energy is not dissipated. After a closed cycle in which the initial energy distribution is fully recovered, the expectation value of a symmetry-breaking observable changes from a value differing from zero in the initial state to zero in the final state. This entails the unavoidable lo...
متن کاملLarge-N scaling behavior of the Lipkin-Meshkov-Glick model.
We introduce a novel semiclassical approach to the Lipkin model. In this way the well-known phase transition arising at the critical value of the coupling is intuitively understood. New results--showing for strong couplings the existence of a threshold energy which separates deformed from undeformed states as well as the divergence of the density of states at the threshold energy--are explained...
متن کاملShortcut to adiabaticity in the Lipkin-Meshkov-Glick model.
We study transitionless quantum driving in an infinite-range many-body system described by the Lipkin-Meshkov-Glick model. Despite the correlation length being always infinite the closing of the gap at the critical point makes the driving Hamiltonian of increasing complexity also in this case. To this aim we develop a hybrid strategy combining a shortcut to adiabaticity and optimal control that...
متن کاملFinite-size scaling exponents of the Lipkin-Meshkov-Glick model.
We study the ground state properties of the critical Lipkin-Meshkov-Glick model. Using the Holstein-Primakoff boson representation, and the continuous unitary transformation technique, we compute explicitly the finite-size scaling exponents for the energy gap, the ground state energy, the magnetization, and the spin-spin correlation functions. Finally, we discuss the behavior of the two-spin en...
متن کاملFisher information and spin squeezing in the Lipkin-Meshkov-Glick model
Fisher information, which lies at the heart of parameter estimation theory, was recently found to have a close relation with multipartite entanglement L. Pezzé and A. Smerzi, Phys. Rev. Lett. 102, 100401 2009 . We use Fisher information to distinguish and characterize behaviors of ground state of the Lipkin-Meskhov-Glick model, which displays a second-order quantum phase transition between the ...
