Moduli Spaces of Cold Holographic Matter
Martin Ammon, Kristan Jensen, Keun-Young Kim +2
We use holography to study (3+1)-dimensional N=4 supersymmetric Yang-Mills theory with gauge group SU(Nc), in the large-Nc and large-coupling limits, coupled to a single massless (…
A Gapless Hard Wall: Magnetic Catalysis in Bulk and Boundary
Stefano Bolognesi, João N. Laia, David Tong +1
We study various aspects of fermions and their chiral condensates, both in the bulk of AdS4 spacetime and in the dual boundary theory. For the most part, we focus on a geometry wit…
Flowing Between Fermionic Fixed Points
João N. Laia, David Tong
We study holographic Wilsonian renormalization group flows for bulk spinor fields in AdS. We use this to compute the all-loop beta function for fermionic double trace operators in…
A Holographic Flat Band
João N. Laia, David Tong
We describe a novel implementation of non-relativistic fermions in AdS/CFT by imposing Lorentz violating boundary conditions for a Dirac spinor in AdS4. The dual boundary theory is…
Non-Abelian Berry Phase, Instantons and N=(0,4) Supersymmetry
João N. Laia
In supersymmetric quantum mechanics, the non-Abelian Berry phase is known to obey certain differential equations. Here we study N=(0,4) systems and show that the non-Abelian Berry…
A new source for a braneworld cosmological constant from a modified gravity model in the bulk
Orfeu Bertolami, Carla Carvalho, Joao Laia
We show that a four-dimensional equation of state for a cosmological constant term arises from a perfect fluid in the bulk in the context of a gravity model where the scalar curvat…
