Three-point correlators of stress tensors in maximally-supersymmetric conformal theories in d = 3 and d = 6
(Elsevier, 2000)We consider free superconformal theories of N = 8 scalar multiplet in d = 3 and (2, 0) tensor multiplet in d = 6 and compute 2-point and 3-point correlators of their stress tensors. The results for the 2-point and the ... -
Three-point Green function of the stress-energy tensor in the AdS/CFT correspondence
(Institute of Physics, 1999)We compute the three-point function of the stress-energy tensor in d-dimensional conformal field theory CFT from AdSd11 gravity. For d54 the coefficients of the three linearly independent conformally covariant forms ... -
Toward the excited meson spectrum of dynamical QCD
(2010)We present a detailed description of the extraction of the highly excited isovector meson spectrum on dynamical anisotropic lattices using a new quark-field construction algorithm and a large variational basis of operators. ... -
Towards Excited Radiative Transitions in Charmonium
(Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2019)In this thesis lattice QCD is utilised to investigate the spectrum of charmonium and charmed mesons with the aim of working towards investigating radiative transitions between excited states in the charmonium spectrum. ... -
Towards Integrability of Topological Strings I: Three Froms on Calabi-
(2004)The precise relation between Kodaira-Spencer path integra l and a particular wave function in seven dimensional quadratic field theory is esta blished. The special properties of three-forms in 6d, as well as Hitchin?s ... -
TT deformations of non-relativistic models
(2021)The light-cone gauge approach to TT¯¯¯¯ deformed models is used to derive the TT¯¯¯¯ deformed matrix nonlinear Schrödinger equation, the Landau-Lifshitz equation, and the Gardner equation. Properties of one-soliton solutions ... -
Tuning anisotropies for dynamical gauge configurations
(SISSA, 2005)We present methods and results for the tuning of quark and gluon anisotropies for improved actions in Nf = 2 QCD. -
Tuning for criticality: A new hypothesis for sleep
(MIT, 2009)We propose that the critical function of sleep is to prevent uncontrolled neuronal feedback while allowing rapid responses and prolonged retention of short-term memories. Through learning, the brain is tuned to react ... -
Two-dimensional gauge theories and quantum integrable systems
(2008)In this paper the relation between 2d topological gauge theo ries and Bethe Ansatz equations is reviewed. 1 In addition we present some new results and clarifications. W e hope the relations discussed here are ... -
Uniform light-cone gauge for strings in AdS(5) x s**5: Solving SU(1|1) sector.
(2006)We introduce a uniform light-cone gauge for strings propagating in AdS5 ?S5 space-time. We use the gauge to analyze strings from the su(1|1) sector, and show that the reduced model is described by a quadratic action for ... -
Universally reversible JC*-triples and operator spaces
(2013)We prove that the vast majority of JC*-triples satisfy the condition of universal reversibility. Our characterisation is that a JC*-triple is universally reversible if and only if it has no triple homomorphisms onto Hilbert ... -
Virasoro amplitude from the S(N) R**24 orbifold sigma model
(Springer, 1998)Four tachyon scattering amplitude is derived from the SNR24 orbifold sigma model in the large N limit. The closed string interaction is described by a vertex which is a bosonic analog of the supersymmetric one, recently ... -
Water waves and Integrability
(Royal Society, 2007)The Euler?s equations describe the motion of inviscid fluid. In the case of shallow water, when a perturbative asymtotic expansion of the Euler?s equations is taken (to a certain order of smallness of the scale parameters), ... -

Weyl's theorem and tensor products: a counterexample.
(Elsevier, 2011)Approximately fifty percent of Weyl's theorem fails to transfer from Hilbert space operators to their tensor product. As a biproduct we find that the product of circles in the complex plane is a limacon. -
The worldsheet low-energy limit of the AdS_4 x CP^3 superstring
(Elsevier, 2010)We consider the AdS_4 x CP^3 superstring sigma-model in the background of the ?spinning string? classical solution, which possesses two Noether spins. In the limit when one of the spins is infinite there are massless ...
