Gravitational Instantons of Type D_k
Sergey A. Cherkis, Nigel J. Hitchin
We use two different methods to obtain Asymptotically Locally Flat hyperkahler metrics of type D_k.
A String Motivated Approach to the Relativistic Point Particle
Michael Tuite, Siddhartha Sen
Using concepts developed in string theory, Cohen, Moore, Nelson and Polchinski calculated the propagator for a relativistic point particle. Following these authors we extend the te…
Integral invariants in N=4 SYM and the effective action for coincident D-branes
J. M. Drummond, P. J. Heslop, P. S. Howe +1
The construction of supersymmetric invariant integrals is discussed in a superspace setting. The formalism is applied to D=4, N=4 SYM and used to construct the F^2, F^4 and (F^5 +…
Hidden Degeneracy in the Brick Wall Model of Black Holes
Kumar S. Gupta, Siddhartha Sen
Quantum field theory in the near-horizon region of a black hole predicts the existence of an infinite number of degenerate modes. Such a degeneracy is regulated in the brick wall m…
Fermion determinant for general background gauge fields
M. P. Fry
An exact representation of the Euclidean fermion determinant in two dimensions for centrally symmetric, finite-ranged Abelian background fields is derived. Input data are the wave…
Relaxation in Conformal Field Theory, Hawking-Page Transition, and Quasinormal/Normal Modes
Danny Birmingham, Ivo Sachs, Sergey N. Solodukhin
We study the process of relaxation back to thermal equilibrium in -dimensional conformal field theory at finite temperature. When the size of the system is much larger than…
