The Resolved Elliptic Genus and the D1-D5 CFT
Marcel R. R. Hughes, Masaki Shigemori
This paper is a follow-up to the short paper arXiv:2509.19425, greatly expanding the discussion with examples and providing derivations and justifications of results presented ther…
Black Hole Entropy from String Entanglement
Soichiro Mori, Tadakatsu Sakai, Masaki Shigemori
We discuss the notion of string entanglement in string theory, which aims to study entanglement between worldsheet Hilbert spaces rather than entanglement between spacetime Hilbert…
A New Supersymmetry Index for the D1-D5 CFT
Marcel R. R. Hughes, Masaki Shigemori
We propose a new supersymmetry index for the D1-D5 CFT for , relevant to the AdS/CFT correspondence. In a novel formulation of symmetric orbifold CFTs based on the Sch…
Conformal field theory on -deformed space and correlators from dynamical coordinate transformations
Shinji Hirano, Masaki Shigemori
We study the map between two descriptions of the deformation of conformal field theory (CFT): One is the defining description as a deformation of CFT by the -o…
Exact Non-Abelian Supertubes
Ryo Nemoto, Masaki Shigemori
Supertubes are supersymmetric configurations in string theory in which branes are extending along a closed curve. For a supertube of codimension two, its dipole charge is character…
Superstrata on Orbifolded Backgrounds
Masaki Shigemori
Some microstates of the Strominger-Vafa black hole are represented by smooth horizonless geometries called superstrata. The standard superstrata are deformations of ${\rm AdS}_3\ti…
Interpolating between multi-center microstate geometries
Masaki Shigemori
We study interpolation between two multi-center microstate geometries in 4d/5d that represent Lunin-Mathur geometries with circular profiles. The interpolating solution is a Lunin-…
Deformation of Stress-Tensor Correlators from Random Geometry
Shinji Hirano, Tatsuki Nakajima, Masaki Shigemori
We study stress-tensor correlators in the -deformed conformal field theories in two dimensions. Using the random geometry approach to the deformation, we devel…
Counting Superstrata
Masaki Shigemori
We count the number of regular supersymmetric solutions in supergravity, called superstrata, that represent non-linear completion of linear fluctuations around empty AdS_3 x S^3. T…
Asymptotically-flat supergravity solutions deep inside the black-hole regime
Iosif Bena, Stefano Giusto, Emil J. Martinec +4
We construct an infinite family of smooth asymptotically-flat supergravity solutions that have the same charges and angular momenta as general supersymmetric D1-D5-P black holes, b…
Non-Abelian Supertubes
Jose J. Fernandez-Melgarejo, Minkyu Park, Masaki Shigemori
A supertube is a supersymmetric configuration in string theory which occurs when a pair of branes spontaneously polarizes and generates a new dipole charge extended along a closed…
Smooth horizonless geometries deep inside the black-hole regime
Iosif Bena, Stefano Giusto, Emil J. Martinec +4
We construct the first family of horizonless supergravity solutions that have the same mass, charges and angular momenta as general supersymmetric rotating D1-D5-P black holes in f…
Codimension-2 Solutions in Five-Dimensional Supergravity
Minkyu Park, Masaki Shigemori
We study a new class of supersymmetric solutions in five-dimensional supergravity representing multi-center configurations of codimension-2 branes along arbitrary curves. Codimensi…
ABJ Theory in the Higher Spin Limit
Shinji Hirano, Masazumi Honda, Kazumi Okuyama +1
We study the conjecture made by Chang, Minwalla, Sharma, and Yin on the duality between the N=6 Vasiliev higher spin theory on AdS_4 and the N=6 Chern-Simons-matter theory, so-call…
Black-Hole Entropy from Supergravity Superstrata States
Iosif Bena, Masaki Shigemori, Nicholas P. Warner
There are, by now, several arguments that superstrata, which represent D1-D5-P bound states that depend upon arbitrary functions of two variables and that preserve four supersymmet…
ABJ Wilson loops and Seiberg Duality
Shinji Hirano, Keita Nii, Masaki Shigemori
We study supersymmetric Wilson loops in the supersymmetric Chern-Simons-matter (CSM) theory, the ABJ theory, at finite , and…
Classifying Supersymmetric Solutions in 3D Maximal Supergravity
Jan de Boer, Daniel R. Mayerson, Masaki Shigemori
String theory contains various extended objects. Among those, objects of codimension two (such as the D7-brane) are particularly interesting. Codimension two objects carry non-Abel…
Perturbative 3-charge microstate geometries in six dimensions
Masaki Shigemori
We construct a set of supersymmetric geometries that represent regular microstates of the D1-D5-P 3-charge system, using the solution generating technique of hep-th/0311092. These…
The Partition Function of ABJ Theory
Hidetoshi Awata, Shinji Hirano, Masaki Shigemori
We study the partition function of the N=6 supersymmetric U(N_1)_k x U(N_2)_{-k} Chern-Simons-matter (CSM) theory, also known as the ABJ theory. For this purpose, we first compute…
Exotic Branes in String Theory
Jan de Boer, Masaki Shigemori
Besides the familiar D-branes, string theory contains a vast number of other non-perturbative objects. While a complete classification is lacking, many of these objects are related…

Iosif Bena, Stefano Giusto, Masaki Shigemori +1
The equations underlying all supersymmetric solutions of six-dimensional minimal ungauged supergravity coupled to an anti-self-dual tensor multiplet have been known for quite a whi…
Double, Double Supertube Bubble
Iosif Bena, Jan de Boer, Masaki Shigemori +1
We argue that there exists a new class of completely smooth 1/8-BPS, three-charge bound state configurations that depend upon arbitrary functions of two variables. These configurat…
Holographic Thermalization
Vijay Balasubramanian, Alice Bernamonti, Jan de Boer +7
Using the AdS/CFT correspondence, we probe the scale-dependence of thermalization in strongly coupled field theories following a quench, via calculations of two-point functions, Wi…
Exotic branes and non-geometric backgrounds
Jan de Boer, Masaki Shigemori
When string/M-theory is compactified to lower dimensions, the U-duality symmetry predicts so-called exotic branes whose higher dimensional origin cannot be explained by the standar…
