Optical forces on an oscillating dipole near VO $_{2}$ phase transition

Daniela Szilard, Patrícia P. Abrantes, Felipe A. Pinheiro +3

We investigate optical forces on oscillating dipoles close to a phase-change vanadium dioxide (VO $_{2}$ ) film, which exhibits a metal-insulator transition around $340$ K and low ther…

Probing topological phase transitions via quantum reflection in the graphene family materials

P. P. Abrantes, Tarik P. Cysne, D. Szilard +3

We theoretically investigate the quantum reflection of different atoms by two-dimensional (2D) materials of the graphene family (silicene, germanene, and stanene), subjected to an…

Negative refraction in the relativistic electron gas

C. A. A. de Carvalho, D. M. Reis, D. Szilard

We show that a gas of relativistic electrons is a left-handed material at low frequencies by computing the effective electric permittivity and effective magnetic permeability that…

A time-dependent harmonic oscillator with two frequency jumps: an exact algebraic solution

D. M. Tibaduiza, L. Pires, A. L. C. Rego +3

We consider a harmonic oscillator (HO) with a time dependent frequency which undergoes two successive abrupt changes. By assumption, the HO starts in its fundamental state with fre…

Resonance energy transfer at percolation transition

P. P. Abrantes, D. Szilard, F. S. S. Rosa +1

We compute the resonance energy transfer (RET) in a system composed of two quantum emitters near a host dielectric matrix in which metallic inclusions are inserted until the medium…

Efficient algebraic solution for a time-dependent quantum harmonic oscillator

D. M. Tibaduiza, L. B. Pires, D. Szilard +3

Using operator ordering techniques based on BCH-like relations of the su(1,1) Lie algebra and a time-splitting approach,we present an alternative method of solving the dynamics of…

Quantum two-photon emission in a photonic cavity

Y. Muniz, D. Szilard, W. J. M. Kort-Kamp +2

We derive a new expression for the two-photon spontaneous emission (TPSE) rate of an excited quantum emitter in the presence of arbitrary bodies in its vicinities. After investigat…

Tuning quantum reflection in graphene with an external magnetic field

Marcius Silvestre, Tarik P. Cysne, Daniela Szilard +2

We theoretically demonstrate that an external magnetic field can be used to control quantum reflection of matter waves in graphene due to its extraordinary magneto-optical properti…

Characterizing critical exponents via Purcell effect

M. B. Silva-Neto, D. Szilard, F. S. S. Rosa +2

We investigate the role of phase transitions into the spontaneous emission rate of quantum emitters embedded in a critical medium. Using a Landau-Ginzburg approach, we find that, i…
