Trapping of a particle in a short-range harmonic potential well
(2013-01-01)
Eigenstates of a particle in a localized and unconfined harmonic potential well are investigated. Effects due to the variation of the potential parameters as well as certain results from asymptotic expansions are discussed. ...

Entanglement entropy in long-range harmonic oscillators
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETYMULHOUSE, 2012)
We study the Von Neumann and Renyi entanglement entropy of long-range harmonic oscillators (LRHO) by both theoretical and numerical means. We show that the entanglement entropy in massless harmonic oscillators increases ...
Quasi-periodic imprints in the equatorial troposphere and stratosphere in three decades of reanalysis data
(Springer Wien, 2013-05)
Wavelet analysis is applied to zonal mean zonal wind and temperature fields to represent characteristics of temporal periodic features different from the annual and semi-annual recurrence in the troposphere and stratosphere. ...
A new methodology for the logistic analysis of evolutionary S-shaped processes: Application to historical time series and forecasting

Use of a Single L1 GPS Receiver for Monitoring Structures: First Results of the Detection of Millimetric Dynamic Oscillations
(ASCE-AMER SOC CIVIL ENGINEERSRESTON, 2012)
This paper presents preliminary results to determine small displacements of a global positioning system (GPS) antenna fastened to a structure using only one L1 GPS receiver. Vibrations, periodic or not, are common in large ...
Low-amplitude variations detected by CoRoT in the B8IIIe star HD 175869
(EDP SCIENCES S A, 2009)
Context. The origin of the short-term variability in Be stars remains a matter of controversy. Pulsations and rotational modulation are the components of the favored hypothesis. Aims. We present our analysis of CoRoT data ...
Optical Microwave Signal Generation for Data Transmission in Optical Networks
(Bogotá - Ingeniería - Doctorado en Ingeniería - Ingeniería EléctricaUniversidad Nacional de Colombia - Sede Bogotá, 2020-06-26)
The massive growth of telecommunication services and the increasing global data traffic boost the development, implementation, and integration of different networks for data transmission. An example of this development is ...
