We propose a set of photonic crystals that realize a nonlinear quantum Rabi model equivalent to a two-level system driven by the phase of a quantized electromagnetic field. The crystals are exactly solvable in the weak-coupling regime; their dispersion relation is discrete and the system is diagonalized by normal modes similar to a dressed state basis. In the strong-coupling regime, we use perturbation theory and find that the dispersion relation is continuous. We give the normal modes of the crystal in terms of continued fractions that are valid for any given parameter set. We show that these photonic crystals allow state reconstruction in the form of coherent oscillations in the weak-coupling regime. In the strong-coupling regime, the general case allows at most partial reconstruction of single waveguide input states, and non-symmetric coherent oscillations that show partial state reconstruction of particular phase-controlled states.
The study was conducted in the village of Filo de Caballos, municipality of Leonardo Bravo, Guerrero, Mexico, from November 2011 to October 2012, in an orchard of Hass avocado, 5 years old. The objective was to evaluate the treatment of chemical and organic nutrition of avocado trees; fertilizers used were: 50 kg tree of cattle dung (manure); 200-100-200 kg ha-1 of N-P-K (edaphic) and 30-10-15.30 kg ha-1 of Ca-Mg-B (foliar). We found that in buds, treatment manure + edaphic + foliar (41 shoots/branch) was better than treatments manure + edaphic (19 shoots/branch), leaf (9 shoots/branch) and the control (21 shoots/branch). And with 17 fruits, manure + treatment + foliar edaphic significantly exceeded the edaphic + foliar treatments (6 fruits), leaf (1 fruit) and the control (3 fruits). The manure + foliar treatment had the highest length (16 cm) of the main shoot, beating the treatment of manure + edaphic (7 cm) and leaf (9 cm). The edaphic + foliar treatment (75 cm2 ) had higher leaf area than control (65 cm2 ) and had the highest fruit weight 2.62 kg with 10 fruits, which was significantly higher than the control (1.51 kg 10 fruits).
this article aims to demonstrate the informal logistics within the political parties in Mexico. It is understood as a mechanism of mediation between militants and leaders. Methodology: from a qualitative approach, the role of informality in the Institutional Revolutionary Party (PRI), the National Action Party (PAN), the Party of the Democratic Revolution (PRD), and the National Regeneration Movement (MORENA) was explored.
