Title: Classical and Quantum Vacuum


1
Classical and Quantum Vacuum
  • Dr. Z.E. Musielak
  • Department of Physics
  • University of Texas at Arlington

2
OUTLINE
  • Classical Vacuum
  • General Relativity (GR) and Its Vacuum
  • Quantum Mechanics (QM) and Its Vacuum
  • Quantum Field Theory (QFT) and Its Vacuum

3
Classical Vaccum
  • Void, nothingness or empty space.
  • Galileo (1638) and Torricelli (1643)
  • Boyle (1645) and Pascal (1647)
  • Von Guericke (1654)
  • Newton (1670) and Leibnitz (1675)

4
Evangelista Torricelli (1608 1647)
5
Torricellis Experiment (1643)
6
Otto von Guericke (1602-1686)
7
Von Guerickes Experiments (1656-1663)

Classical Vaccum with Ether
  • Ether in otherwise empty space.
  • Maxwell (1865)
  • Michelson and Morley (1887)
  • Lorentz (1895)
  • Einstein (1905)

10
Maxwells Unification
  • In 1865, James Clerk Maxwell unified the laws of
    electricity and magnetism into one
    electromagnetic theory
  • The speed of light c is the fundamental speed of
    the theory

11
Light as Electromagnetic Wave
Maxwell (1859)
12
Einsteins Special Theory of Relativity
  • In 1905, Albert Einstein introduced Special
    Theory of Relativity.
  • Ether does not exist!

13
General Theory of Relativity
  • Einstein (1915) developed the theory and
  • established the field equations that describe
  • how geometry of spacetime is determined by
  • the distribution of matter and energy.

14
Curved Space-Time
Einstein (1915)
15
The Cosmological Constant
  • Einstein (1916) added a constant ? to his
  • field equations the constant describes
  • additional tension of spacetime (repulsive
  • force) acting against gravity.
