A reality proof in PT-symmetric quantum mechanics
Patrick Dorey, Clare Dunning, Roberto Tateo
We review the proof of a conjecture concerning the reality of the spectra of certain PT-symmetric quantum mechanical systems, obtained via a connection between the theories of ordi…
Differential equations and the Bethe ansatz
P. Dorey, C. Dunning, A. Millican-Slater +1
We review some surprising links which have been discovered in the last few years between the theory of certain ordinary differential equations, and particular integrable lattice mo…
Finite lattice Bethe ansatz systems and the Heun equation
Patrick Dorey, Junji Suzuki, Roberto Tateo
We study the P"oschl-Teller equation in complex domain and deduce infinite families of TQ and Bethe ansatz equations, classified by four integers. In all these models the form of T…
Thermodynamic Bethe ansatz for the AII sigma-models
Andrei Babichenko, Roberto Tateo
We derive thermodynamic Bethe ansatz equations describing the vacuum energy of the SU(2N)/Sp(N) nonlinear sigma model on a cylinder geometry. The starting points are the recently-p…
