    On a family of nonlinear difference equations of the fifth order solvable in closed form by Stevo Stević, Bratislav Iričanin, Witold Kosmala

    Published 2023-07-01
    “…We present some closed-form formulas for the general solution to the family of difference equations $ x_{n+1} = \Phi^{-1}\left(\Phi(x_{n-1})\frac{{\alpha} \Phi(x_{n-2})+{\beta} \Phi(x_{n-4})}{{\gamma} \Phi(x_{n-2})+{\delta} \Phi(x_{n-4})}\right), $ for $ n\in{\mathbb N}_0 $ where the initial values $ x_{-j} $, $ j = \overline{0, 4} $ and the parameters $ {\alpha}, {\beta}, {\gamma} $ and $ {\delta} $ are real numbers satisfying the conditions $ {\alpha}^2+{\beta}^2\ne 0, $ $ {\gamma}^2+{\delta}^2\ne 0 $ and $ \Phi $ is a function which is a homeomorphism of the real line such that $ \Phi(0) = 0, $ generalizing in a natural way some closed-form formulas to the general solutions to some very special cases of the family of difference equations which have been presented recently in the literature. …”

    Scale Invariance in the Lowest Landau Level by Hofmann, Johannes, Zwerger, Wilhelm

    Published 2023-06-01
    “…Moreover, we show that for contact interactions $\sim g_2 \delta ^{(2)}(\mathbf{x})$, which are scale invariant at the classical level, the non-commutativity of the guiding center coordinates gives rise to a quantum anomaly in the commutator $i [\hat{H}_{\mathrm{LLL}}, \hat{D}_R] = (2 + \ell \partial _\ell ) \hat{H}_{\mathrm{LLL}}$ with the dilatation operator $\hat{D}_R$ in the LLL, which replaces the trace anomaly in the absence of a magnetic field. …”
