Quantization of the AdS3 superparticle on OSP(1|2)2/SL(2,R)

Nuclear Physics B, 2017
We analyze AdS3 superparticle dynamics on the coset OSP(1|2)×OSP(1|2)/SL(2,R). The system is quantized in canonical coordinates obtained by gauge invariant Hamiltonian reduction.

Canonical domains for coadjoint orbits

Journal of the London Mathematical Society, 2023
AbstractThis paper describes two real analytic symplectomorphisms defined on appropriate dense open subsets of any coadjoint orbit of a compact semisimple Lie algebra. The first symplectomorphism sends the open dense subset to a bounded subset of a standard cotangent bundle.

Superconformal blocks from Wilson lines with loop corrections

Journal of High Energy Physics, 2018
We compute the N=1 $$ \mathcal{N}=1 $$ superconformal blocks from the networks of open Wilson lines in the osp(1|2) Chern-Simons theory in the expansion of large central charge c.

Spectral theory and nonlinear problems Théorie spectrale et problèmes non-linéaires [PDF]

Surveys in Mathematics and its Applications, 2010
We present a Lie algebra theoretical schema leading to integrable systems, based on the Kostant-Kirillov coadjoint action. Many problems on Kostant-Kirillov coadjoint orbits in subalgebras of infinite dimensional Lie algebras (Kac-Moody Lie algebras)

Geometric actions for Lower Spin Gravity

Journal of High Energy Physics
We perform the Hamiltonian reduction of Lower Spin Gravity, the simplest bulk dual for a Warped Conformal Field Theory (WCFT), consisting in an SL(2) × U(1) Chern-Simons model.

Compact Coadjoint Orbits

, 2003
I give an answer to the question ``Which groups have compact coadjoint orbits?''. Whilst I thought that the answer, which is straightforward, must be in the literature, I was unable to find it. This note aims to rectify this. It is also a plea: If the result is already published then I would like to be told the reference.

Strict quantization of coadjoint orbits [PDF]

Journal of Mathematical Physics, 1998
A strict quantization of a compact symplectic manifold S on a subset I⊆R, containing 0 as an accumulation point, is defined as a continuous field of C*-algebras {Aℏ}ℏ∈I, with A0=C0(S), and a set of continuous cross sections {Q(f)}f∈C∞(S) for which Q0(f)=f.

Vacuum block thermalization in semi-classical 2d CFT

Journal of High Energy Physics, 2019
The universal nature of black hole collapse in asymptotically AdS3 gravitational theories suggests that its holographic dual process, thermalization, should similarly be fixed by the universal features of 2d CFT with large central charge c.

Fluid Implicit Particles on Coadjoint Orbits

ACM Transactions on Graphics
We propose Coadjoint Orbit FLIP (CO-FLIP), a high order accurate, structure preserving fluid simulation method in the hybrid Eulerian-Lagrangian framework. We start with a Hamiltonian formulation of the incompressible Euler Equations, and then, using a local, explicit, and high order divergence free interpolation, construct a modified Hamiltonian ...
