Brane Tilings, M2-branes and Chern-Simons Theories

John Davey, Amihay Hanany, Noppadol Mekareeya +1

We investigate (2+1)-dimensional quiver Chern-Simons theories that arise from the study of M2-branes probing toric Calabi-Yau 4-folds. These theories can be elegantly described usi…

Pohlmeyer-reduced form of string theory in AdS_5 x S^5: semiclassical expansion

B. Hoare, Y. Iwashita, A. A. Tseytlin

We consider the Pohlmeyer-reduced formulation of the AdS_5 x S^5 superstring. It is constructed by introducing new variables which are algebraically related to supercoset current c…

Holographic superconductivity in M-Theory

Jerome P. Gauntlett, Julian Sonner, Toby Wiseman

Using seven-dimensional Sasaki-Einstein spaces we construct solutions of D=11 supergravity that are holographically dual to superconductors in three spacetime dimensions. Our numer…

The central charge of supersymmetric AdS_5 solutions of type IIB supergravity

Maxime Gabella, Jerome P. Gauntlett, Eran Palti +2

We show that generic supersymmetric AdS_5 solutions of type IIB supergravity admit a canonical contact structure. This structure determines the central charge of the dual field the…

Geometry of the N=2 supersymmetric sigma model with Euclidean worldsheet

C. M. Hull, U. Lindstrom, L. Melo dos Santos +2

We investigate the target space geometry of supersymmetric sigma models in two dimensions with Euclidean signature, and the conditions for N=2 supersymmetry. For a real action, the…

Small- behavior of the Non-Hermitian PT-Symmetric Hamiltonian

Carl M. Bender, Karim Besseghir, Hugh F. Jones +1

The energy eigenvalues of the class of non-Hermitian PT-symmetric Hamiltonians () are real, positive, and discrete. The behavior of these eigenvalues has…
