Bethe Ansatz for Yangian Invariants: Towards Super Yang-Mills Scattering Amplitudes

Rouven Frassek, Nils Kanning, Yumi Ko +1

We propose that Baxter's Z-invariant six-vertex model at the rational gl(2) point on a planar but in general not rectangular lattice provides a way to study Yangian invariants. The…

Coherent states, 6j symbols and properties of the next to leading order asymptotic expansions

Wojciech Kaminski, Sebastian Steinhaus

We present the first complete derivation of the well-known asymptotic expansion of the SU(2) 6j symbol using a coherent state approach, in particular we succeed in computing the de…

Melons are branched polymers

Razvan Gurau, James P. Ryan

Melonic graphs constitute the family of graphs arising at leading order in the 1/N expansion of tensor models. They were shown to lead to a continuum phase, reminiscent of branched…

Quantization maps, algebra representation and non-commutative Fourier transform for Lie groups

Carlos Guedes, Daniele Oriti, Matti Raasakka

The phase space given by the cotangent bundle of a Lie group appears in the context of several models for physical systems. A representation for the quantum system in terms of non-…

Solutions of the Klein-Gordon equation in an infinite square-well potential with a moving wall

Michael Koehn

Employing a transformation to hyperbolic space, we derive in a simple way exact solutions for the Klein-Gordon equation in an infinite square-well potential with one boundary movin…
