We describe the ab initio control of photons in highly-dispersive slow-light photonic crystals and superlattices. Ultrafast nonlinearities such as chip-scale four-wave mixing, regenerative oscillations, self-phase modulation, and phase-resolved soliton dynamics and compression will be highlighted.

Effective theory of interacting fermions in shaken square optical lattices
Keleş, Ahmet; Liu, W. Vincent (2017-06-01)
We develop a theory of weakly interacting fermionic atoms in shaken optical lattices based on the orbital mixing in the presence of time-periodic modulations. Specifically, we focus on fermionic atoms in a circularly shaken square lattice with near-resonance frequencies, i.e., tuned close to the energy separation between the s band and the p bands. First, we derive a time-independent four-band effective Hamiltonian in the noninteracting limit. Diagonalization of the effective Hamiltonian yields a quasienerg...
Scalar mesons in radiative phi-meson decays into charged k-meson states
Öztürk, Fahri; Gökalp, Ahmet; Department of Physics (2008)
The role of $f_{0}(980)$ and $a_{0}(980)$ scalar meson intermediate states in the mechanism of radiative $\phi (1020)$ meson decay into two charged $K (494)$ mesons and a photon $\phi\rightarrow K^{+} + K^{-} + \gamma$ is investigated. For the contribution of scalar meson intermediate state two models are considered. In the kaon-loop model, the scalar meson intermediate state couples the final state to the initial $\phi$ meson through a charged kaon-loop. The second model, called no-structure model, consist...
Magnetic moment of the rho meson in QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2003-09-01)
The magnetic moment mu of the rho meson is studied in QCD light cone sum rules, and it is found that mu=(2.3+/-0.5), in units of e/2m(rho). A comparison of our result on the magnetic moment of the rho meson with the predictions of the other approaches is presented.
Refractive index, static dielectric constant, energy band gap and oscillator parameters of Ga2SeS single crystals
Qasrawi, A. F.; Hasanlı, Nızamı (Wiley, 2007-09-01)
The optical properties of Bridgman method grown Ga2SeS crystals have been investigated by means of room-temperature transmittance and reflectance spectral analysis. The optical data have revealed direct and indirect allowed transition band gaps of 2.49 and 2.10 eV, respectively. The room-temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as...
Dispersive optical constants and temperature tuned band gap energy of Tl2InGaS4 layered crystals
Goksen, K.; Hasanlı, Nızamı; Ozkan, H. (IOP Publishing, 2007-06-27)
The optical properties of Tl2InGaS4 layered single crystals have been studied by means of transmission and reflection measurements in the wavelength range of 400-1100 nm. The analysis of the room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 2.35 and 2.54 eV, respectively. Transmission measurements carried out in the temperature range of 10-300 K revealed that the rate of change of the indirect band gap with temperature is gamma =...
