Gravity duals for nonrelativistic conformal field theories
K Balasubramanian, J McGreevy - Physical Review Letters, 2008 - APS
We attempt to generalize the anti–de Sitter/conformal field theory correspondence to
nonrelativistic conformal field theories which are invariant under Galilean transformations. Such …

Hot spacetimes for cold atoms
A Adams, K Balasubramanian… - Journal of High Energy …, 2008 - iopscience.iop.org
Building on our earlier work and that of Son, we construct string theory duals of non-relativistic
critical phenomena at finite temperature and density. Concretely, we find black hole …

Thermoacoustic instability in a Rijke tube: Non-normality and nonlinearity
K Balasubramanian, RI Sujith - Physics of Fluids, 2008 - pubs.aip.org
The role of non-normality and nonlinearity in thermoacoustic interaction in a Rijke tube is
investigated in this paper. The heat release rate of the heating element is modeled by a …

An analytic Lifshitz black hole
K Balasubramanian, J McGreevy - Physical Review D, 2009 - APS
A Lifshitz point is described by a quantum field theory with anisotropic scale invariance (but
not Galilean invariance). In [8], gravity duals were conjectured for such theories. We …

Losing forward momentum holographically
K Balasubramanian, CP Herzog - Classical and Quantum Gravity, 2014 - iopscience.iop.org
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 …

The particle number in Galilean holography
K Balasubramanian, J McGreevy - Journal of High Energy Physics, 2011 - Springer
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 in the …

Nonlinear response of diffusion flames to uniform velocity disturbances
K Balasubramanian, RI Sujith - Combustion science and …, 2008 - Taylor & Francis
This article presents an investigation of the nonlinear response of a diffusion flame to
unsteady velocity disturbances. The infinite rate chemistry flame model is employed to study …

Non-normality and its consequences in active control of thermoacoustic instabilities
R Kulkarni, K Balasubramanian… - Journal of Fluid …, 2011 - cambridge.org
Non-normality can cause transient growth of perturbations in thermoacoustic systems with
stable eigenvalues. This can cause low-amplitude perturbations to grow to amplitudes high …
