Ja n 19 97 DETERMINISTIC EXCLUSION PROCESS WITH A STOCHASTIC DEFECT : MATRIX - PRODUCT GROUND STATES
We study a one-dimensional anisotropic exclusion model describing particles moving deterministically on a ring with a single defect across which they move with probability 0 < q < 1. We show that the stationary state of this model can be represented as a matrix-product state.
In this Rapid Communication we report on the autoionization dynamics of the 5d7d doubly excited state in barium in a static electric field. The different experiments and theory show Stark beatings in the autoionization process. Also it appears that the total spin of the two valence electrons plays a major role in the ionization dynamics. Absorption spectroscopy revealed the ionization dynamics ...
Abstract. In this paper it is shown that the steady-state weights of the asymmetric simple exclusion process (ASEP) with open boundaries and parallel update can be written as a product of a scalar pair-factorized and a matrix-product state. This type of state is also obtained for an ASEP on a ring in which particles can move one or two sites. The dynamics leads to the formation of an excess hol...
Patellofemoral kinematics after a limited resurfacing of the trochlea was investigated. Patellofemoral contact pressure, area, and force were measured for intact state; after creation of a 20-mm full-thickness trochlear defect; and after trochlear resurfacing implant (Arthrosurface) in serial flexion positions (45 degrees, 60 degrees, 75 degrees). In the defect state, edge loading and peak cont...
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.
Research on advanced materials such as multiferroic perovskites underscores promising applications, yet studies on these materials rarely address the impact of defects on the nominally expected materials property. Here, we revisit the comparatively simple oxide MgO as the model material system for spin-polarized solid-state tunnelling studies. We present a defect-mediated tunnelling potential l...
