Focusing performance of small f-number metallic lens with depth-modulated slits

引用

Chinese physics B 2010年第12期19卷 242-247页

作者：高扬张学如王玉晓宋瑛林刘树田 department of physics Harbin Institute of Technology

This paper studies a small f-number metallic lens with depth-modulated slits. Slits filled with dielectric between silver plates are designed to produce desired optical phase retardations based on the particular propagation properties of surface plasmon polaritons in nanostructures. Numerical simulation of this structure is performed through the finite- difference time-domain method. Different from the conventional dielectric lens, the metallic lens can be used as a pure phase element without energy loss brought by the light refraction at curved surfaces and total internal reflection. The focusing performance is consequently improved, with larger diffraction efficiency than that of the same shaped dielectric lens.

Elimination of spiral waves and spatiotemporal chaos by the pulse with a specific spatiotemporal configuration

引用

Chinese physics B 2008年第5期17卷 1925-1934页

作者：袁国勇杨世平王光瑞陈式刚 department of physics Hebei Normal University institute of Applied physics and Computational Mathematics

Spiral waves and spatiotemporal chaos are sometimes harmful and should be controlled. In this paper spiral waves and spatiotemporal chaos are successfully eliminated by the pulse with a very specific spatiotemporal configuration. The excited position D of spiral waves or spatiotemporal chaos is first recorded at an arbitrary time （to）. When the system at the domain D enters a recovering state, the external pulse is injected into the domain. If the intensity and the working time of the pulse are appropriate, spiral waves and spatiotemporal chaos can finally be eliminated because counter-directional waves can be generated by the pulse. There are two advantages in the method. One is that the tip can be quickly eliminated together with the body of spiral wave, and the other is that the injected pulse may be weak and the duration can be very short so that the original system is nearly not affected, which is important for practical applications.

All the Weyl points are well separated in momentum space and possess nearly the same energy due to high crystalline ***, both the Weyl points and Fermi arcs are highly tunable by varying Pb/Sn composition, pressure, magnetization,temperature, surface potential, etc., opening up the possibility of manipulating Weyl points and rewiring the Fermi arcs.

Coherence destruction of tunneling in a quantum-dot molecule with bias

引用

Chinese physics B 2010年第10期19卷 445-451页

作者：钟光辉王立民 department of physics Hebei Normal University institute of Applied physics and Computational Mathematics

This paper studies the constraint conditions for coherence destruction in tunneling by using perturbation theory and numerical simulation for an AC-field with bias and Coulomb interaction between electrons in a quantum dot molecule. Such conditions can be described by using the roots of a Bessel function Jn（x）, where n is determined by both the bias and the Coulomb interactions, and x is the ratio of the amplitude to the frequency of the AC-field. Under such conditions, a coherent suppression of tunneling occurs between localized electronic states, which results from the dynamical localization phenomenon. All the conditions are verified with numerical simulations.

Nonlinear transport of Bose-Einstein condensates in a double barrier potential

引用

Chinese physics B 2008年第11期17卷 3996-4001页

作者：方见树 institute of physics Hunan University of Technology department of physics Hunan University of Technology

The stable nonlinear transport of the Bose-Einstein condensates through a double barrier potential in a waveguide is studied. By using the direct perturbation method we have obtained a perturbed solution of Cross-Pitaevskii equation. Theoretical analysis reveals that this perturbed solution is a stable periodic solution, which shows that the transport of Bose-Einstein condensed atoms in this system is a stable nonlinear transport. The corresponding numerical results are in good agreement with the theoretical analytical results.

Simulation of ECR Startup and Comparison with Experimental Observations in SUNIST

引用

Plasma Science and Technology 2011年第1期13卷 30-35页

作者：谭熠高喆王龙 department of Engineering physics Tsinghua University institute of physics Chinese Academy of Sciences

Transient process of ECR startup in SUNIST is analyzed and simulated in a one- dimensional model. Contributions from the generation, drift, diffusion and loss of electrons are taken into account in the model and estimated from experimental parameters, e.g., toroidal field, vertical field and gas filling pressure. Typical discharges are simulated with the conditions close to the experimental ones. Experimental and simulated results are comparable qualitatively in amplitudes and semi-quantitatively in time. From the results it is confirmed that the transient process of ECR startup ill SUNIST is dominated, as preliminarily deduced from experimental observations, by a pair of exclusive factors, namely the absorption, due to gas ionization, and the reflection of microwave, caused by the shift of over dense plasmas due to outward E x B drift. In addition to these two factors, electron loss along the field line is also very important in determining the character of discharges.

Steady bipartite coherence induced by non-equilibrium environment

引用

Science China(physics,Mechanics & Astronomy) 2018年第1期61卷 19-29页

作者： Yong Huangfu Jun Jing institute of Atomic and Molecular physics Jilin University department of physics Zhejiang University

We study the steady state of two coupled two-level atoms interacting with a non-equilibrium environment that consists of two heat baths at different temperatures. Specifically, we analyze four cases with respect to the configuration about the interactions between atoms and heat baths. Using secular approximation, the conventional master equation usually neglects steady-state coherence,even when the system is coupled with a non-equilibrium environment. When employing the master equation with no secular approximation, we find that the system coherence in our model, denoted by the off-diagonal terms in the reduced density matrix spanned by the eigenvectors of the system Hamiltonian, would survive after a long-time decoherence evolution. The absolute value of residual coherence in the system relies on different configurations of interaction channels between the system and the heat baths. We find that a large steady quantum coherence term can be achieved when the two atoms are resonant. The absolute value of quantum coherence decreases in the presence of additional atom-bath interaction channels. Our work sheds new light on the mechanism of steady-state coherence in microscopic quantum systems in non-equilibrium environments.
