Dark-bright quadratic solitons with a focusing effective Kerr nonlinearity

Fri, 2018-01-19 11:00

Author(s): Manna Chen, Xiaorou Ping, Guo Liang, Qi Guo, Daquan Lu, and Wei Hu

Dark solitons are traditionally considered to exist in defocusing Kerr nonlinearity media. We investigate dark quadratic solitons with a focusing effective Kerr nonlinearity and a sine-oscillatory nonlocal response. A nonlinear refractive index with a focusing sine-oscillatory response leads to a de...

Hamiltonian design to prepare arbitrary states of four-level systems

Fri, 2018-01-19 11:00

Author(s): Yi-Chao Li, D. Martínez-Cercós, S. Martínez-Garaot, Xi Chen, and J. G. Muga

We propose a method to manipulate four-level systems with specific coupling configurations by means of time-dependent couplings and constant energy shifts (detunings in quantum-optical realizations). We inversely engineer the Hamiltonian, in ladder, tripod, or diamond configurations, to prepare arbi...

Author(s): Xiao-Dong Chen, Ding Zhao, Xiao-Sheng Zhu, Fu-Long Shi, Huan Liu, Jin-Cheng Lu, Min Chen, and Jian-Wen Dong

Edge states of photonic crystals have attracted much attention for the potential applications, such as high transmission waveguide bends, spin-dependent splitters, and one-way photonic circuits. Here, we theoretically discuss and experimentally observe the deterministic edge states in checkerboard p...

Disordered resonant media: Self-induced transparency versus light localization

Thu, 2018-01-18 11:00

Author(s): Denis V. Novitsky

We propose a concept of disordered resonant media, which are characterized by random variations of their parameters along the light propagation direction. In particular, a simple model of disorder considered in the paper implies random change of the density of active particles (two-level atoms). Wit...

Radiation-pressure-mediated control of an optomechanical cavity

Author(s): Jonathan Cripe, Nancy Aggarwal, Robinjeet Singh, Robert Lanza, Adam Libson, Min Jet Yap, Garrett D. Cole, David E. McClelland, Nergis Mavalvala, and Thomas Corbitt

We describe and demonstrate a method to control a detuned movable-mirror Fabry-Pérot cavity using radiation pressure in the presence of a strong optical spring. At frequencies below the optical spring resonance, self-locking of the cavity is achieved intrinsically by the optomechanical (OM) interact...

Heralded entangling quantum gate via cavity-assisted photon scattering

Thu, 2018-01-18 11:00

Author(s): Halyne S. Borges, Daniel Z. Rossatto, Fabrício S. Luiz, and Celso J. Villas-Boas

We theoretically investigate the generation of heralded entanglement between two identical atoms via cavity-assisted photon scattering in two different configurations, namely, either both atoms confined in the same cavity or trapped into locally separated ones. Our protocols are given by a very simp...

Analog gravity by an optical vortex: Resonance enhancement of Hawking radiation

Wed, 2018-01-17 11:00

Author(s): Marco Ornigotti, Shimshon Bar-Ad, Alexander Szameit, and Victor Fleurov

Propagation of coherent light in a Kerr nonlinear medium can be mapped onto a flow of an equivalent fluid. Here we use this mapping to model the conditions in the vicinity of a rotating black hole as a Laguerre–Gauss vortex beam. We describe weak fluctuations of the phase and amplitude of the electr...

Modal analysis of wave propagation in dispersive media

Wed, 2018-01-17 11:00

Author(s): M. Ismail Abdelrahman and B. Gralak

Surveys on wave propagation in dispersive media have been limited since the pioneering work of Sommerfeld [Ann. Phys. 349, 177 (1914)] by the presence of branches in the integral expression of the wave function. In this article a method is proposed to eliminate these critical branches and hence to e...

Dissipative phase transition in the open quantum Rabi model

Wed, 2018-01-17 11:00

Author(s): Myung-Joong Hwang, Peter Rabl, and Martin B. Plenio

We demonstrate that the open quantum Rabi model (QRM) exhibits a second-order dissipative phase transition (DPT) and propose a method to observe this transition with trapped ions. The interplay between the ultrastrong qubit-oscillator coupling and the oscillator damping brings the system into a stea...

Effect of Cherenkov radiation on localized-state interaction

Tue, 2018-01-16 11:00

Author(s): A. G. Vladimirov, S. V. Gurevich, and M. Tlidi

We study theoretically the interaction of temporal localized states in all fiber cavities and microresonator-based optical frequency comb generators. We show that Cherenkov radiation emitted in the presence of third-order dispersion breaks the symmetry of the localized structures interaction and gre...

Analytical modeling of soliton interactions in a nonlocal nonlinear medium analogous to gravitational force

Author(s): Shihao Zeng, Manna Chen, Ting Zhang, Wei Hu, Qi Guo, and Daquan Lu

We illuminate an analytical model of soliton interactions in lead glass by analogizing to a gravitational force system. The orbits of spiraling solitons under a long-range interaction are given explicitly and demonstrated to follow Newton's second law of motion and the Binet equation by numerical si...

Author(s): Clai Owens, Aman LaChapelle, Brendan Saxberg, Brandon M. Anderson, Ruichao Ma, Jonathan Simon, and David I. Schuster

Topological and strongly correlated materials are exciting frontiers in condensed-matter physics, married prominently in studies of the fractional quantum Hall effect [H. L. Stormer et al., Rev. Mod. Phys. 71, S298 (1999)], There is an active effort to develop synthetic materials where the microsco...

Magnetic dipole-dipole interaction induced by the electromagnetic field

Tue, 2018-01-16 11:00

Author(s): Jiaxuan Wang, Hui Dong, and Sheng-Wen Li

We give a derivation for the indirect interaction between two magnetic dipoles induced by the quantized electromagnetic field. It turns out that the interaction between permanent dipoles directly returns to the classical form; the interaction between transition dipoles does not directly return to th...

Fast macroscopic-superposition-state generation by coherent driving

Tue, 2018-01-16 11:00

Author(s): Emi Yukawa, G. J. Milburn, and Kae Nemoto

We propose a scheme to generate macroscopic superposition states (MSSs) in spin ensembles, where a coherent driving field is applied to accelerate the generation of macroscopic superposition states. The numerical calculation demonstrates that this approach allows us to generate a superposition of tw...

Author(s): Fam Le Kien, Tridib Ray, Thomas Nieddu, Thomas Busch, and Síle Nic Chormaic

We investigate the electric quadrupole interaction of an alkali-metal atom with guided light in the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We calculate the quadrupole Rabi frequency, the quadrupole oscillator strength, and their enhancement factors. In the examp...

Author(s): Qiang Zhang, Junqing Li, Xingguang Liu, Demissie J. Gelmecha, and Weigang Zhang

We reveal a behavior of screwdriving of a surface plasmonic field formed near a surface of strongly chiral material, where lateral force and torque can be provided by the quantum spin Hall effect of light simultaneously. We study the role of chirality strength of the material in optical manipulating...

Comprehensive solutions to the Bloch equations and dynamical models for open two-level systems

Fri, 2018-01-12 11:00

Author(s): Thomas E. Skinner

The Bloch equation and its variants constitute the fundamental dynamical model for arbitrary two-level systems. Many important processes, including those in more complicated systems, can be modeled and understood through the two-level approximation. It is therefore of widespread relevance, especiall...
