Title: Decoherent dynamics of two nonclassically correlated particles

Abstract

We investigate the dynamics of nonclassical correlations between two particles in a harmonic trap which interact in a pointlike manner. Via a quantum-jump approach we add a specific damping model. The correlations between the particles are quantified using a Bell-type correlation function, adapted for the continuous-variable case. They clearly exceed the classical border and show collapses and revivals. Their destruction due to decoherence strongly depends on the initial separation of the particles and on the damping constant.

  • The linear and nonlinear dynamical susceptibilities of a two-level system are calculated as it undergoes a transition to a decoherent state. Analogously to the Glover-Tinkham-Ferrell sum rule of superconductivity, spectral weight in the linear susceptibility is continuously transferred from a finite frequency resonance to nearly zero frequency, corresponding to a broken symmetry in the thermodynamic limit. In this respect, the behavior of the present model (the Mermin model) differs from the spin-boson model. The third order nonlinear susceptibility, corresponding to two-photon absorption, has an unexpected nonmonotonic behavior as a function of the environmental coupling, reaching a maximum within the decoherentmore » phase of the model. Both linear and nonlinear susceptibilities may be expressed in a universal form. (c) 2000 The American Physical Society.« less
  • In this paper we present results of finite-lattice studies of the {ital t}-{ital J} and the {ital t}-{ital t}{prime}-{ital J} model for 18 (20) sites with up to 4 (2) holes. A modified Lanczos algorithm allowed for the classification of the ground state according to total spin {ital S}. In the one-hole sector we find evidence for the existence of hole pockets. We calculate the effective quasiparticle band and show qualitative differences between the {ital t}-{ital J} and {ital t}-{ital t}{prime}-{ital J} model for {ital J}{approx gt}0.2. As {ital U} increases we notice a substantial band narrowing, which is maximalmore » at the Nagaoka transition, accompanied by {ital S}-level crossings rendering a quasiparticle description difficult. In the high-doping regime we present hole binding energies for up to six holes for the {ital t}-{ital J} model. Evidence for phase separation is only found for {ital J}{gt}{ital t}. We also studied the magnetic structure of the ground state on the 18-site lattice in the limit {ital J}=0. We present a complete ground-state classification for all numbers of holes {ital N}{sub {ital h}} and find {ital S}={ital S}{sub max} at quarter filling in addition to the Nagaoka case.« less
  • In this Letter we describe a new technique for investigating phase transitions and dynamics in interacting electron systems. This technique is based on the derivation and self-consistent solution of infinite-order conserving approximations. It provides a new approach to the study of two-particle correlations with strong frequency and momentum dependence. We use this technique to derive a low-temperature phase diagram and dynamic correlation functions for the two-dimensional Hubbard model.
  • Long-lived excitonic coherence in photosynthetic proteins has become an exciting area of research because it may provide design principles for enhancing the efficiency of energy transfer in a broad range of materials. In this publication, we provide new evidence that long-lived excitonic coherence in the Fenna-Mathew-Olson pigment-protein (FMO) complex is consistent with the assumption of cross correlation in the site basis, indicating that each site shares bath fluctuations. We analyze the structure and character of the beating crosspeak between the two lowest energy excitons in two-dimensional (2D) electronic spectra of the FMO Complex. To isolate this dynamic signature, we usemore » the two-dimensional linear prediction Z-transform as a platform for filtering coherent beating signatures within 2D spectra. By separating signals into components in frequency and decay rate representations, we are able to improve resolution and isolate specific coherences. This strategy permits analysis of the shape, position, character, and phase of these features. Simulations of the crosspeak between excitons 1 and 2 in FMO under different regimes of cross correlation verify that statistically independent site fluctuations do not account for the elongation and persistence of the dynamic crosspeak. To reproduce the experimental results, we invoke near complete correlation in the fluctuations experienced by the sites associated with excitons 1 and 2. This model contradicts ab initio quantum mechanic/molecular mechanics simulations that observe no correlation between the energies of individual sites. This contradiction suggests that a new physical model for long-lived coherence may be necessary. The data presented here details experimental results that must be reproduced for a physical model of quantum coherence in photosynthetic energy transfer.« less
  • Two-dimensional electronic-vibrational (2DEV) spectroscopy is an experimental technique that shows great promise in its ability to provide detailed information concerning the interactions between the electronic and vibrational degrees of freedom in molecular systems. The physical quantities 2DEV is particularly suited for measuring have not yet been fully determined, nor how these effects manifest in the spectra. In this work, we investigate the use of the center line slope of a peak in a 2DEV spectrum as a measure of both the dynamic and static correlations between the electronic and vibrational states of a dye molecule in solution. We show howmore » this center line slope is directly related to the solvation correlation function for the vibrational degrees of freedom. We also demonstrate how the strength with which the vibration on the electronic excited state couples to its bath can be extracted from a set of 2DEV spectra. These analytical techniques are then applied to experimental data from the laser dye 3,3′-diethylthiatricarbocyanine iodide in deuterated chloroform, where we determine the lifetime of the correlation between the electronic transition frequency and the transition frequency for the backbone C = C stretch mode to be ∼1.7 ps. Furthermore, we find that on the electronic excited state, this mode couples to the bath ∼1.5 times more strongly than on the electronic ground state.« less
