Bosonic Amplification of Noise-Induced Suppression of Phase Diffusion

Abstract

We study the effect of noise-induced dephasing on collisional phase diffusion in the two-site Bose-Hubbard model. Dephasing of the quasimomentum modes may slow down phase diffusion in the quantum Zeno limit. Remarkably, the degree of suppression is enhanced by a bosonic factor of order N/logN as the particle number N increases.

Decoherence and entanglement in a bosonic Josephson junction: Bose-enhanced quantum Zeno control of phase diffusion

Yuri Khodorkovsky, Gershon Kurizki, Amichay Vardi

We study the effect of decoherence on dynamical phase diffusion in the two-site Bose-Hubbard model. Starting with an odd parity excited coherent state, the initial loss of single-particle coherence varies from small bound oscillations in the Rabi regime, through hyperbolic depletion in the Josephson regime, to a Gaussian decay in the Fock regime. The inclusion of local-site noise, measuring the relative number difference between the modes, is shown to enhance phase diffusion. In comparison, site-indiscriminate noise measuring the population imbalance between the two quasimomentum modes slows down the loss of single-particle coherence. Decoherence thus either enhances or suppresses phase diffusion, depending on the details of system-bath coupling and the overlap of decoherence pointer states with collisional-entanglement pointer states. The deceleration of phase diffusion due to the coupling with the environment may be viewed as a many-body quantum Zeno effect. The extended effective decay times in the presence of projective measurement are further enhanced with increasing number of particles $N$ by a bosonic factor of $\sqrt{N}$ in the Fock regime and $N/\text{log}\text{ }N$ in the Josephson regime.

Quantum-Zeno Control of Collisional Entanglement in a Bose-Josephson Junction

Amichay Vardi, Yuri Khodorkovsky, Gershon Kurizki

We propose a scheme to control the collision-induced entanglement between atoms in the two-site Bose-Hubbard model, by means of site-indiscriminate noise. This decoherence mechanism induces the continuous measurement of the quasi-momentum, protecting single-particle coherence via a Bose-enhanced many-body Quantum-Zeno effect.

Quantum Zeno control of coherent dissociation

Christine Khripkov, Amichay Vardi

We study the effect of dephasing on the coherent dissociation dynamics of an atom-molecule Bose-Einstein condensate. We show that when phase-noise intensity is strong with respect to the inverse correlation time of the stimulated process, dissociation is suppressed via a Bose enhanced quantum Zeno effect. This is complementary to the quantum Zeno control of phase-diffusion in a bimodal condensate by symmetric noise [Phys. Rev. Lett. 100, 220403 (2008)] in that the controlled process here is phase formation and the required decoherence mechanism for its suppression is purely phase noise.

Quantum Zeno effect in noisy integrable quantum circuits for impurity models

Yicheng Tang, Pradip Kattel, J. H. Pixley +1 more

We theoretically study the open quantum system dynamics (in the Trotterized limit) of integrable quantum circuits in the presence of on-site dephasing noise with a spin-1/2 ``impurity'' interacting at the edge. Using a combination of Bethe ansatz (BA) and exact diagonalization (ED), we study the dynamics of both the bulk and the impurity for the XXX (Heisenberg) and the XX qubit chains with and without bulk noise. In the absence of noise, we show that the impurity exhibits two distinct phases: the bound-mode phase, where the impurity undergoes persistent oscillations, and the Kondo phase, where it decays with Kondo time ${t}_{K}$. Turning on the bulk dephasing noise, we find for the two models that in the long-time limit in both regimes, the quantum Zeno effect takes place where the dynamics of the impurity magnetization slows down as the noise strength $\ensuremath{\gamma}$ increases. In contrast, the impurity magnetization in the bound-mode regime shows the opposite effect, decaying faster as the noise strength increases at short times $(t\ensuremath{\ll}1/\ensuremath{\gamma})$. We show that the Zeno effect slows down the impurity dynamics in the long-time limit, driven by the transition in bulk dynamics from ballistic (KPZ) universality class in the XX (XXX) chain to diffusive dynamics in the presence of noise.

Squeezing in driven bimodal Bose-Einstein condensates: Erratic driving versus noise

Christine Khripkov, Amichay Vardi, Doron Cohen

We study the interplay of squeezing and phase randomization near the hyperbolic instability of a two-site Bose-Hubbard model in the Josephson interaction regime. We obtain results for the quantum Zeno suppression of squeezing far beyond the previously found short time behavior. More importantly, we contrast the expected outcome with the case where randomization is induced by erratic driving with the same fluctuations as the quantum noise source, finding significant differences. These are related to the distribution of the squeezing factor, which has log-normal characteristics: hence its average is significantly different from its median due to the occurrence of rare events.

Negative differential conductivity and quantum statistical effects in a three-site Bose-Hubbard model

M. K. Olsen, Joel Frederick Corney

The use of an electron beam to remove ultracold atoms from selected sites in an optical lattice has opened up new opportunities to study transport in quantum systems [R. Labouvie et al., Phys. Rev. Lett. 115, 050601 (2015)]. Inspired by this experimental result, we examine the effects of number difference, dephasing, and initial quantum statistics on the filling of an initially depleted middle well in the three-well inline Bose-Hubbard model. We find that the well-known phenomenon of macroscopic self-trapping is the main contributor to oscillatory negative differential conductivity in our model, with phase diffusion being a secondary effect. However, we find that phase diffusion is required for the production of direct atomic current, with the coherent process showing damped oscillatory currents. We also find that our results are highly dependent on the initial quantum states of the atoms in the system.
