Physics 530 Spring 2019
General Relativity
Notes:
The classrooms for the lectures are Henn 302 for Tues ,Thus 2:00,
Text:
No assigned text book. There are a number of books which are useful
- Wald-- General Relativity--Probably the best book from the
mathematical point of view. He gets things right.
- Misner, Thorne, Wheeler-- Gravitation. Huge and discursive. It covers
a lot of material
- Carroll-- Lecture Notes on Relativity --
http://preposterousuniverse.com/grnotes/
Or also in book form Spacetime and Geometry: An Introduction to
General Relativity
There are a number of other books available as well.
I will also upon occasion put up some lecture notes, Assignments,
announcements here
My office is Henn 311 (inside to table and turn right) The return assignment
tray is beside the door.
Phone: (604) 822 3853
Course: This will cover the field of gravity or General Relativity. I intend
to cover gravity waves fairly extensively, but will also cover Tensor
analysis, Black hole solutions, and quantum effects around black holes.
There will be assignments in the course worth from 20-25% of the grade, an
essay due on the last day of class (worth 30-35%) and a final exam worth the
rest of the marks.
Lecture cancellation Jan8 and 10
During the second week of classes, Jan 6-11, I will be away attending a The
International Quantum Electronics conference (I have to go because they are
giving me an award) During this time I expect you to review your Special
Relativity course that you got as undergraduates so that you are really
prepared for General Relativity which builds in an essential way on Special
Relativity. I have set an assignment to do during this week.
Final Exam
: Tuesday April 9th at 12.00pm will appear on Student
Services online in the next day or two.
Notes
- Vectors, Abstract indicees.
- Christophel Symbols Derivation of the
covariant derivative by following the more usual procedure of making
certain demands on the definition of derivative. This makes it seem
far more arbitrary and mysterious than it is.
- Derivation of Parallel transport from
metric Note that the "parallalogram" procedure in these
notes is slightly different from the one I used in class. In these
notes the parallelogram is used to displace the curve through the point at
gamma(lambda) defining the vector at lambda, to the a curve through
gamma(0) instead of the other way around as in the lecture. This makes
no difference to the result.
- Lectures on Lie derivatives.
- Curvature These notes are very
similar to what Wald does in his book Ch. 3. The definition of the index
order in the curvature tensor is different but due to the symmeteries
of the curvature, my tensor is equal to his.
- Linearization of the curvature
tensor (altered Feb 27/2019)
- Perihelion advance and Einstei's
luck (New versin Mar 12/2019
- Kennefink's 2009 analysis of the
Eddington/Dyson experiment
- Schwartzschild solution including
Eddington Finkelstein coordinates, and Kruskal
- Orbits in Schwartzschild including
perihelion advance, light deflection, Shapiro time delay, Nordtvedt
effect. (Some Misprints corrected and small additions Mar2/19).
- Gravitational waves solutions Including
full non-linear plane wave solution.
- Einsten-Rosen paper on
non-linear gravitational waves in Journal Franklin Inst.
223, Pages 43-54 (1937). A previous version of this paper had been
sent to Phys Rev, where the referee HP Robertson had suggested that
the paper was wrong in that it argued that gravitational radiation did
not exist because of the singularity of the solution. Given the first
section
they probably found the Plane wave solutions where the spatial
components of the metric go to zero. They did not recognize that these
were purely coordinate singularities. (That was only done by Bondi,
Pirani and Robinson after the war. See Dan
Kennefink in Physics Today
Physics Today 58, 9, 43 (2005)
Einstein was so upset that the journal had sent his paper to be
refereed that he never again published in Phys Rev.
- Bondi, Pirani, Robinson paper on
plane gravitational waves.
- Talk I gave on Ligo Grav. Wave
detection
- ADM formalism for equations
- Penrose conformal
transformation for Vaidya collapse metric.
- Measurements on the double
pulsar
- Papapetrou's paper on deriving
geodesic equations from conservation of Energy Momentum tensor. Note
that the script T tensor is the tensor density sqrt(|g|) times the
energy momentum tensor.
- Geroch and Jang's paper making the previous one a bit more rigorous.
- Dixon extended Papapetrou's
treatment to higher moments.
- "Swiss cheese" model for cosmolgy
Model in which a spherical void in the dust cosmology is replaced by a
Schwartzschild solution with continuity across the boundary.
This could also be done for pressure cosmologies, but a shell of
pressure (negative surface tension) would be needed to hold back the pressure
of the cosmology.
- PhysRevD.14.870 Notes on Black
Hole evaporation-- "original" paper with acceleration radiation and
expansion on black hole evaporation.
- Fulling ,Ruijsenaars Temperature,
periodicity and horizons Proof of periodicity in imaginary
time.
- Bogoliubov -- [Corrections Mar 25]paper describing the
generic definition of creation and annihilation operators
independently of the Hamiltonian. The special case where they are
related to the Hamiltonian (Hamiltonian diagonalization) are also described.
- Field Theory The application
of the previous work to field theory, and its application to
Cosmological particle creation of a scalar field, and the problem with
"Hamiltonian diagonalization" as a reasonable definition of
"particles."
