Isotropic-medium three-dimensional cloaks for acoustic and electromagnetic waves
, 2012 We propose a generalization of the two-dimensional eikonal-limit cloak derived from a conformal transformation to three dimensions. The proposed cloak is a spherical shell composed of only isotropic media; it operates in the transmission mode and ...

Quantum Reflection as a New Signature of Quantum Vacuum Nonlinearity [PDF]
, 2013 We show that photons subject to a spatially inhomogeneous electromagnetic field can experience quantum reflection. Based on this observation, we propose quantum reflection as a novel means to probe the nonlinearity of the quantum vacuum in the presence ...

A General Class of Metamaterial Transformation Slabs [PDF]
, 2010 In this paper, we apply transformation-based optics to the derivation of a general class of transparent metamaterial slabs. By means of analytical and numerical full-wave studies, we explore their image displacement/formation capabilities, and establish ...

Critical dynamical properties of a first-order dissipative phase transition
, 2017 We theoretically investigate the critical properties of a single driven-dissipative nonlinear photon mode. In a well-defined thermodynamical limit of large excitation numbers, the exact quantum solution describes a first-order phase transition in the ...

Optically bistable driven-dissipative Bose-Hubbard dimer: Gutzwiller approaches and entanglement
, 2017 We theoretically examine the driven-dissipative Bose-Hubbard dimer in the optical bistable regime. Various approximation schemes based on a Gutzwiller mean field decoupling are applied and compared.
