Casimir energy for twisted piecewise uniform bosonic strings

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

The Casimir energy for the transverse oscillations of piecewise uniform bosonic strings with either untwisted or twisted continuous conditions is discussed. After calculating the analytic values of zeros of the dispersion function under certain conditions, we obtain the Casimir energy for both open and closed bosonic strings composed of two or three segments.
