    Abstract: It has been shown earlier that the measure of entanglement between two nearest neighbor spins ina spin system given by concurrence is related to the Berry phase acquired by the ground state whenit evolves in a closed path. The significant aspect of this quantization procedure is that it has the specific property of coordinate independence and is go... Show More

    Abstract: Photovoltaic solar energy consists of the direct conversion of sunlight into electricity by means of solar cells. These cells, electrically interconnected in series and/or in parallel, form the photovoltaic generator (GPV). The efficiency of the GPV is influenced by the irradiation and the temperature. In the intertropical zone, these two atmospher... Show More
  • Laser Beam Joining of the Material Pairings Aluminum/Polyamide and Aluminum/Polyvinylchloride

    Abstract: The article presents a process optimization of laser beam joining of the material pairings EN AW-6082 (AlSi1MgMn)/polyamide 6.6 and EN AW-6082/polyvinylchloride hard. The materials selection focuses on their distinct mechanical and electrical properties. Al and PA-6.6 are both widely used but dissimilar light-weighting materials for engineering app... Show More
