Cosmic Strings Stabilized by Fermion Fluctuations
H. Weigel, M. Quandt, N. Graham
We provide a thorough exposition of recent results on the quantum stabilization of cosmic strings. Stabilization occurs through the coupling to a heavy fermion doublet in a reduced…
Duality between 1+1 dimensional Maxwell-Dilaton gravity and Liouville field theory
Simone Zonetti, Jan Govaerts
We present an interesting reformulation of a collection of dilaton gravity models in two space-time dimensions into a field theory of two decoupled Liouville fields in flat space,…
Dressed Fermions, Modular Transformations and Bosonization in the Compactified Schwinger Model
Michaël Fanuel, Jan Govaerts
The celebrated exactly solvable "Schwinger" model, namely massless two-dimensional QED, is revisited. The solution presented here emphasizes the non- perturbative relevance of the…
Giant Graviton Oscillators
Robert de Mello Koch, Matthias Dessein, Dimitrios Giataganas +1
We study the action of the dilatation operator on restricted Schur polynomials labeled by Young diagrams with p long columns or p long rows. A new version of Schur-Weyl duality pro…
Non-commutative Quantum Mechanics in Three Dimensions and Rotational Symmetry
Debabrata Sinha, Biswajit Chakraborty, Frederik G Scholtz
We generalize the formulation of non-commutative quantum mechanics to three dimensional non-commutative space. Particular attention is paid to the identification of the quantum Hil…
Nonplanar Integrability: Beyond the SU(2) Sector
Robert de Mello Koch, Badr Awad Elseid Mohammed, Stephanie Smith
We compute the one loop anomalous dimensions of restricted Schur polynomials with a classical dimension Δ\sim O(N). The operators that we consider are labeled by Young diagrams wit…
