Interacción de un láser con un ion atrapado incluyendo dependencia temporal

Vargas-Martínez, J.M.; Martí-Panameño, E. A.; Moya-Cessa, H.
2009-12-01

Resumen en español En la actualidad es posible atrapar iones individuales en trampas de Paul o de Penning, las partículas cargadas son confinadas en el espacio mediante campos electromagnéticos. Un ion atrapado puede contener mucha energía vibracional, lo cual es indeseable en ciertas aplicaciones. En este artículo, partiendo del hamiltoniano de un ion atrapado en un potencial armónico, se demuestra que es posible encontrar transiciones tipo Jaynes-Cummings y anti-Jaynes-Cummings en el (mas) régimen de intensidad intermedia, es decir, ajustando la intensidad del láser que induce el acoplamiento entre los estados internos y vibracionales del ion proporcionalmente a la frecuencia de vibración del ion; estas transiciones son de utilidad porque hacen posible extraer dicha energía vibracional. En nuestro tratamiento consideramos que el ion y el láser están en resonancia, lo que elimina la necesidad de usar láseres sintonizables. También analizamos el problema de un ion atrapado en una trampa dependiente del tiempo interactuando con un haz láser. Mediante un conjunto de transformaciones unitarias con parámetros dependientes del tiempo mostramos que este sistema es equivalente a la interacción entre un haz cuantizado y un sistema de dos niveles con parámetros dependientes del tiempo. El hamiltoniano es linealizado de tal forma que puede ser resuelto mediante métodos que se encuentran en la literatura y que involucran parámetros dependientes del tiempo. La linealización está libre de aproximaciones y de consideraciones sobre los parámetros del sistema, como son, por ejemplo, el parámetro de Lamb- Dicke, la dependencia temporal de la frecuencia de la trampa y la desintonía, con lo que se logra obtener la mejor solución para este tipo de sistemas. También mostramos un caso particular de dependencia temporal de la trampa. Resumen en inglés Nowadays it is possible to trap single ions in Paul or Penning traps, charged particles are confined in space via electromagnetic fields. A trapped ion can have a lot vibrational energy which is undesirable in some applications. In this paper, starting from the Hamiltonian of a trapped ion in a harmonic potential, we show that it is possible to get Jaynes-Cummings and anti- Jaynes- Cummings- like transitions in the intermediate intensity regime, that is, adjusting the int (mas) ensity of the laser that induce the coupling between the internal and vibrational states of the ion proportionally to the vibrational frequency of the ion; these transitions are useful because make it possible to extract the vibrational energy. In our treatment we consider that the ion and the laser are in resonance what eliminate the need of using tuned lasers. Also, the problem of a trapped ion in a trap with time-dependent parameters interacting with a laser field is analyzed. By using a set of time-dependent unitary transformations is shown that this system is equivalent to the interaction between a quantized field and a two level system with time dependent parameters. The Hamiltonian is linearized in such a way that can be solved with methods that are found in some papers and that involve time-dependent parameters. The linearization is free of approximations and assumptions on the parameters of the system as are, for instance, the Lamb-Dicke parameter, the time-dependency of the frequency trap and the detuning, with what we can obtain the best solution for this kind of system. Also, we show a particular case of time-dependency of the trap.

Resumen en español En este trabajo se determinó cualitativa y cuantitativamente la composición química de un extracto en benceno de ejemplares de Rhodnius prolixus en diferentes estadios ninfales y edades reproductivas de las hembras. El análisis fue realizado mediante técnicas uni- y bidimensionales (1D y 2D) de Resonancia Magnética Nuclear (RMN). Se han clasificado los compuestos químicos presentes en el extracto como A, B y C, según sus zonas de desplazamiento químico. El compue (mas) sto A, situado en la zona entre d 5,0 y 5,33 ppm, puede ser atribuido a hidrógenos olefínicos (alquenos) y está presente en todo los estadios ninfales y edades reproductivas, por lo que no es de utilidad para ser marcador de edades. El Compuesto C, situado en la zona entre 2,5 ppm y 3,5 ppm, representa distintas señales las cuales presumiblemente según sus desplazamientos químicos corresponden a hidrógenos sobre carbonos nitrogenados y sirve como marcador de edad para diferenciar entre los estadios ninfales y el comienzo de la edad adulta. El Compuesto B, presente en la zona entre 4 y 5 ppm, corresponde a un triacilglicerol, y es un marcador importante para diferenciar entre las hembras no ovipositoras (HNO) y ovipositoras (HO), ya que esta última edad carece de este compuesto. También es útil usar la relación de concentraciones de los compuestos A y B, que viene dada por la integral de la señal para determinar la diferencia de edades entre los estadios ninfales. Se proponen estas técnicas para determinar los estadios ninfales y las edades reproductivas de las hembras en una muestra de triatominos colectados en condiciones de campo, lo que revelaría información importante para conocer algunas de las variables de las que depende la capacidad vectora de estos insectos en la transmisión de la Enfermedad de Chagas Resumen en inglés The quantitative and qualitative chemical composition of a benzene extract from Rhodnius prolixus females at different nymphal state and at different reproductive ages were determined, using uni- and bi-dimensional NMR techniques. The chemical compounds present in the mixture were classified as A, B and C, according to their NMR chemical shifts. Compound A has signals in the range of d 5.0 and 5.33 ppm,which is attributed to olefinic hidrogen and is found in all nymphal s (mas) tates and reproductive ages, therefore is not of utility as an age marker. Compoun C located between d 2.5 and 3.5 could be attributed to hydrogen over nitrogen-bearing carbons, is very useful as an age marker to differentiate between the nymphal states and the beginning of the adult age. While compound B showing signalds between ä 4.0 and 5.0 ppm was identified as tri-acyglycerol, is and important marker to differentiate between non-ovipositor and ovipositor females, since this last age has none of this compound. It is also very useful to use the concentrations ratio of compound A relative to B, which is given by the ratio of their integrals, to establish the age difference of the nymphal states. We propose this technique to determine the nymphal states and the reproductive age of R. prolixus females, in a sample of triatomine collected at field conditions, which reveals an important information on the variables related to vector efficiency in Chagas disease
