Understanding the electromagnetic 4-potential in the tetrad bundle
, 2018 Separation of the spin and orbital angular momenta of the electromagnetic field has been discussed frequently in recent years. The spin and orbital angular momenta cannot be made simultaneously gauge invariant and Lorentz covariant and are not conserved ...

Deducing effective light transport parameters in optically thin systems [PDF]
, 2015 We present an extensive Monte Carlo study on light transport in optically thin slabs, addressing both axial and transverse propagation. We completely characterize the so-called ballistic-to-diffusive transition, notably in terms of the spatial variance ...

Protecting OAM Photons from Decoherence in a Turbulent Atmosphere
, 2013 One of the most important properties of orbital angular momentum (OAM) of photons is that the Hilbert space required to describe a general quantum state is infinite dimensional.

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 ...

Signature of strong atom-cavity interaction on critical coupling
, 2010 We study a critically coupled cavity doped with resonant atoms with metamaterial slabs as mirrors. We show how resonant atom-cavity interaction can lead to a splitting of the critical coupling dip.

Fermat's principle with complex refractive indices and local light-ray rotation [PDF]
, 2009 We describe local light-ray rotation in terms of complex refractive indices. We show that Fermat's principle holds, and we derive an extended Snell's law.

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.

Feasibility of giant fiber-optic gyroscopes [PDF]
, 2013 The availability of long-distance, underground fiber-optic links opens a perspective of implementing interferometric fiber-optic gyroscopes embracing very large areas. We discuss the potential sensitivity, some disturbances and approaches to overcome them.

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 ...
