Abstract We study D = 11 supergravity solutions which are dual to one-dimensional superconformal defects in d = 3 SCFTs. We consider defects in ABJM theory with monodromy for U(1)4 ⊂ SO(8) global symmetry, as well as in 𝒩 = 2 mABJM SCFT, which a

Abstract We study type IIB supergravity solutions that are dual to two-dimensional superconformal defects in d = 4 SCFTs which preserve N $$ \mathcal{N} $$ = (0, 2) supersymmetry. We consider solutions dual to defects in N $$ \mathcal{N} $$ = 4 SYM t

Abstract We construct a new class of supersymmetric AdS3 × Y 7 solutions of type IIB supergravity, where Y 7 is an S 5 fibration over a spindle, which are dual to d = 2, N $$ \mathcal{N} $$ = (0, 2) SCFTs. The solutions are constructed in a sub-trun

Abstract We construct a continuous one parameter family of AdS4 × S 1 × S 5 S-fold solutions of type IIB string theory which have nontrivial SL(2, ℤ) monodromy in the S 1 direction. The solutions span a subset of a conformal manifold that contain

Abstract We construct infinite new classes of AdS4 × S 1 × S 5 solutions of type IIB string theory which have non-trivial SL(2, ℤ) monodromy along the S 1 direction. The solutions are supersymmetric and holographically dual, generically, to N $$

Abstract We construct new families of deformed supersymmetric field theories which break space-time symmetries but preserve half of the original supersymmetry. We do this by writing deformations as couplings to background multiplets. In many cases it

Abstract We construct gravitational solutions that holographically describe two different d = 4 SCFTs joined together at a co-dimension one, planar RG interface and preserving d = 3 superconformal symmetry. The RG interface joins N $$ \mathcal{N} $$

Abstract We study mass deformations of N $$ \mathcal{N} $$ = 4, d = 4 SYM theory that are spatially modulated in one spatial dimension and preserve some residual supersymmetry. We focus on generalisations of N $$ \mathcal{N} $$ = 1∗ theories and sh

Abstract Missed fractures are the most common diagnostic error in emergency departments and can lead to treatment delays and long-term disability. Here we show through a multi-site study that a deep-learning system can accurately identify fractures t

Abstract We consider real mass and FI deformations of ABJM theory preserving supersymmetry in the large N limit, and compare with holographic results. On the field theory side, the problems amounts to a spectral problem of a non-Hermitian Hamiltonian
