We find non-critical string backgrounds in five and eight dimensions, holographically related
to four-dimensional conformal field theories with Script N= 0 and Script N= 1 …

Stringy structure at the BPS bound

EJ Martinec, S Massai, D Turton - Journal of High Energy Physics, 2020 - Springer
A bstract We explore the stringy structure of 1/2-BPS bound states of NS fivebranes carrying
momentum or fundamental string charge, in the decoupling limits leading to little string …

Little strings, long strings, and fuzzballs

EJ Martinec, S Massai, D Turton - Journal of High Energy Physics, 2019 - Springer
A bstract At high energy densities, fivebranes are populated by a Hagedorn phase of so-
called little strings, whose statistical mechanics underlies black fivebrane thermodynamics …

String theory of supertubes

EJ Martinec, S Massai - Journal of High Energy Physics, 2018 - Springer
A bstract String theory on AdS 3 backgrounds arises as an IR limit of Little String Theory on
NS5-branes. A wide variety of holographic RG flows from the fivebrane theory in the UV to …

A Gadde, E Pomoni, L Rastelli - arXiv preprint arXiv:0912.4918, 2009 - arxiv.org
We attack the long-standing problem of finding the AdS dual of N= 2 superconformal QCD,
the N= 2 super Yang Mills theory with gauge group SU (N_c) and N_f= 2 N_c fundamental …

AdS3's with and without BTZ's

EJ Martinec - arXiv preprint arXiv:2109.11716, 2021 - arxiv.org
This companion paper to arXiv: 2109.00065 explores the interpretation of $ AdS_3/CFT_2 $
duality for $ k=(R_ {AdS}/\lstr)^ 2< 1$ in terms of" non-critical little string theory". We review …

A defect in AdS3/CFT2 duality

EJ Martinec - Journal of High Energy Physics, 2022 - Springer
A bstract AdS 3 string theory in the stringy regime k=(R AdS/ℓ s) 2< 1 provides a laboratory
for the study of holography in which both sides of AdS/CFT duality are under fairly good …

A note on integrability loss in fuzzball geometries

M Emelin, S Massai - Fortschritte der Physik, 2023 - Wiley Online Library
The dynamics of certain string configurations in a class of fivebrane supertube backgrounds
is studied. In the decoupling limit of the fivebranes, these solutions are known to admit an …

D-branes in N= 2 Liouville theory and its mirror

D Israël, A Pakman, J Troost - Nuclear Physics B, 2005 - Elsevier
We study D-branes in the mirror pair N= 2 Liouville/supersymmetric SL (2, R)/U (1) coset
superconformal field theories. We build D0-, D1-and D2-branes, on the basis of the …

Little string amplitudes (and the unreasonable effectiveness of 6D SYM)

CM Chang, YH Lin, SH Shao, Y Wang, X Yin - Journal of High Energy …, 2014 - Springer
A bstract We study tree level scattering amplitudes of four massless states in the double
scaled little string theory, and compare them to perturbative loop amplitudes in six …
