Losing Forward Momentum Holographically
Koushik Balasubramanian, Christopher P. Herzog
We present a numerical scheme for solving Einstein's Equations in the presence of a negative cosmological constant and an event horizon with planar topology. Our scheme allows for…
Time-Dependent Warping and Non-Singular Bouncing Cosmologies
Koushik Balasubramanian, Sujan P. Dabholkar
In this note, we construct a family of non-singular time-dependent solutions of a six-dimensional gravitational theory that are warped products of a four dimensional bouncing cosmo…
Non-normality in combustion-acoustic interaction in diffusion flames: a critical revision
Luca Magri, K. Balasubramanian, R. I. Sujith +1
Perturbations in a non-normal system can grow transiently even if the system is linearly stable. If this transient growth is sufficiently large, it can trigger self-sustained oscil…
Gravity duals of cyclic RG flows, with strings attached
Koushik Balasubramanian
In this note, we propose gravity duals for 3+1 dimensional Lorentz invariant theories exhibiting discrete scale invariance. We construct non-singular solutions of a six dimensional…
String theory duals of Lifshitz-Chern-Simons gauge theories
Koushik Balasubramanian, John McGreevy
We propose candidate gravity duals for a class of non-Abelian z=2 Lifshitz Chern-Simons (LCS) gauge theories studied by Mulligan, Kachru and Nayak. These are nonrelativistic gauge…
The particle number in Galilean holography
Koushik Balasubramanian, John McGreevy
Recently, gravity duals for certain Galilean-invariant conformal field theories have been constructed. In this paper, we point out that the spectrum of the particle number operator…
