Evolution of entanglement after a local quench
We study free electrons on an infinite half-filled chain, starting in the ground state with a bond defect. We find a logarithmic increase of the entanglement entropy after the defect is removed, followed by a slow relaxation towards the value of the homogeneous chain. The coefficients depend continuously on the defect strength.
متن کاملDensity of Topological Defects After a Quench
We present results of numerical studies of the Landau-Ginzburg dynamics of the order parameter in one-dimensional models inspired by the condensed matter analogues of cosmological phase transitions. The main goal of our work is to show that, as proposed by one of us [1], the density of the frozen-out topological defects is set by the competition between the quench rate — the rate at which the p...
متن کاملStrongly correlated fermions after a quantum quench.
Using the adaptive time-dependent density-matrix renormalization group method, we study the time evolution of strongly correlated spinless fermions on a one-dimensional lattice after a sudden change of the interaction strength. For certain parameter values, two different initial states (e.g., metallic and insulating) lead to observables which become indistinguishable after relaxation. We find t...
متن کامل3D Contour Closing: A local operator based on Chamfer distance transformation
Visual perception evolved in a world of objects many of which are bounded by smooth closed contours. Especially with the three-dimensional dataset that need to be marked the locations of filaments to get the region of interest. There also exist other structures with high values (noise) or we may loose some information within the image through contour detection process. For instance, a simple gl...
متن کاملQuantum relaxation after a quench in systems with boundaries.
We study the time dependence of the magnetization profile, m(l)(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with an exponentially decreasing period the local magnetization arrives to a quasistationary regime, which is followed by an exponentially fast reconstruction period. The nonthermal behavior observed at near-surface sites...
