G 2 Domain Walls in M-theory
نویسنده
چکیده
M-theory is considered in its low-energy limit on a G2 manifold with non-vanishing flux. Using the Killing spinor equations for linear flux, an explicit set of first-order bosonic equations for supersymmetric solutions is found. These solutions describe a warped product of a domain wall in four-dimensional space-time and a deformed G2 manifold. It is shown how these domain walls arise from the perspective of the associated four-dimensional N = 1 effective supergravity theories. We also discuss the inclusion of membrane and M5-brane sources. email: [email protected] email: [email protected]

Quantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls
The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
متن کاملDomain walls and perturbation theory in high temperature gauge theory : SU ( 2 ) in 2 + 1 dimensions
We study the detailed properties of Z2 domain walls in the deconfined high temperature phase of the d = 2 + 1 SU(2) gauge theory. These walls are studied both by computer simulations of the lattice theory and by one-loop perturbative calculations. The latter are carried out both in the continuum and on the lattice. We find that leading order perturbation theory reproduces the detailed propertie...
متن کاملModuli Spaces and Brane Solitons for M - Theory Compactifications on Holonomy
We investigate the local geometry on the moduli space of G 2 structures that arises in compactifications of M-theory on holonomy G 2 manifolds. In particular, we determine the homogeneity properties of couplings of the associated N = 1, D = 4 supergravity under the scaling of moduli space coordinates. We then find some brane solitons of N = 1, D = 4 supergravity that are associated with wrappin...
متن کاملOn Domain Walls of N = 1 Supersymmetric Yang-Mills in Four Dimensions
We study the BPS domain walls of supersymmetric Yang-Mills for arbitrary gauge group G. We describe the degeneracies of domain walls interpolating between arbitrary pairs of vacua. A recently proposed large N duality sheds light on various aspects of such domain walls. In particular, for the case of G = SU(N) the domain walls correspond to wrapped D-branes giving rise to a 2+1 dimensional U(k) ...
متن کاملOn Realising N=1 Super Yang-mills in M Theory
Pure N =1 super Yang-Mills theory can be realised as a certain low energy limit of M theory near certain singularities in G 2-holonomy spaces. For SU(n) and SO(2n) gauge groups these M theory backgrounds can be regarded as strong coupling limits of wrapped D6-brane configurations in Type IIA theory on certain non-compact Calabi-Yau spaces such as the deformed conifold. Various aspects of such r...
