DESCRIPTION:NAdS2 holography has recently been studied extensively as not
only it provides a gravity analogue of maximally chaotic quantum systems b
ut also because it can potentially answer some fundamental questions in qu
antum gravity. For both purposes\, it is necessary to understand time- dep
endent behavior. We explicitly construct exact time-dependent classical NA
dS2 solutions involving sources of irrelevant operators with dimensions be
tween 1 and 3/2. We also construct semi-holographic models involving back-
reacted source and with total conserved energy. In both cases\, we find th
at NAdS2 holographic systems can behave in totally different ways compared
to its higher dimensional analogues. Particularly\, even in the classical
bulk approximation\, reversible transfer of energy from bulk to boundary
source is possible. We can find the final steady state solution in a large
range of semi-holographic coupling. We also argue that even in the classi
cal bulk approximation we will need need to incorporate AdS2 fragmentation
to make sense of the most general scenario. Our semi-holographic model ca
n have applications in understanding of behavior of di-quarks in quark-glu
on plasma.\n\nhttps://indico.tifr.res.in/indico/conferenceDisplay.py?confI
