A braided Yang–Baxter algebra in a theory of two coupled lattice quantum KdV: algebraic properties and ABA representations
A generalization of the Yang–Baxter algebra is found in quantizing the monodromy matrix of two (m)KdV equations discretized on a space lattice. This braided Yang–Baxter equation still ensures that the transfer matrix generates operators in involution which form the Cartan sub-algebra of the braided quantum group. Representations diagonalizing these operators are described through relying on an easy generalization of algebraic Bethe ansatz techniques. The conjecture that this monodromy matrix algebra leads, in the cylinder continuum limit, to a perturbed minimal conformal field theory description is analysed and supported.

Non-linear integral equations in N = 4 SYM ∗
We survey and discuss the applications of the non-linear integral equation in the framework of the Bethe Ansatz type equations which are conjectured to give the eigenvalues of the dilatation operator in N = 4 SYM. Moreover, an original idea (different from that of [1]) to derive a non-linear integral equation is briefly depicted in Section 4.

CVD diamond films as photon detectors
Abstract We present an overview of our research on Chemical Vapour Deposited (CVD) diamond films as photon detectors. Samples are grown in our laboratories using three different methods: microwave plasma enhanced CVD (MWPECVD), DC glow discharge CVD (DCGDCVD) and hot filament CVD (HFCVD). We present the photoelectrical properties of these samples having contacts in planar and sandwich configuration, taking into account the roles of material microstructure and electrical configuration. Their photoresponse has been measured in the whole visible–near UV spectral range with the aim to characterize their UV selectivity and to evaluate their gap-state density.
