Cosmological perturbations in the 5D Big Bang
Jaume Garriga, Takahiro Tanaka
Bucher [Bucher2001] has recently proposed an interesting brane-world cosmological scenario where the ``Big Bang'' hypersurface is the locus of collision of two vacuum bubbles which…
Moduli effective action in warped brane world compactifications
Jaume Garriga, Oriol Pujolas, Takahiro Tanaka
We consider a class of 5-D brane-world solutions with a power-law warp factor , and bulk dilaton with profile , where is the proper distance…
D6-branes wrapping Kahler four-cycles
Joaquim Gomis, Toni Mateos
We construct supergravity duals of D6-branes wrapping Kahler four-cycles inside a Calabi-Yau threefold, CY_3. We obtain the purely gravitational M-theory description, which turns o…
Noncompact Heisenberg spin magnets from high-energy QCD: I. Baxter Q-operator and Separation of Variables
S. E. Derkachov, G. P. Korchemsky, A. N. Manashov
We analyze a completely integrable two-dimensional quantum-mechanical model that emerged in the recent studies of the compound gluonic states in multi-color QCD at high energy. The…
Noncommutative Quantum Mechanics: The Two-Dimensional Central Field
J. Gamboa, M. Loewe, F. Mendez +1
Quantum mechanics in a noncommutative plane is considered. For a general two dimensional central field, we find that the theory can be perturbatively solved for large values of the…
The Landau problem and noncommutative quantum mechanics
J. Gamboa, M. Loewe, F. Mendez +1
The conditions under which noncommutative quantum mechanics and the Landau problem are equivalent theories is explored. If the potential in noncommutative quantum mechanics is chos…
