Speaker: Marc Schulz
Subject: Confinement effects in Cobalt Niobate

In my presentation, I will talk about confinement effects in one-dimensional quantum systems. As a start, I will review the features of the inelastic neutron scattering data on CoNb2O6[1] realizing the predictions of Ref.[2]. After this review, I'll introduce the effective model to explain the experimental findings and present its solution as performed in Ref. [3] (and references therein). If time allows, I will mention also other approaches including e.g. TEBD [4].
