We present low resolution optical spectroscopy for six cataclysmic variable candidates and the old nova V888Cen. We confirm the classification as cataclysmic variable for LB 9963 and FQMon, while the other four candidates turn out to be different type of stars. We discuss the individual spectra and pay special attention to the mass transfer rate and disc temperature and density of the three cat...

The main goal of the ALICE Muon spectrometer experiment is the measurement of heavy quark production in p+p, p+A and A+A collisions at LHC energies, via the muonic channel. Physics motivations and expected performances have been presented in this talk. 1. Physics motivations Heavy ion collisions (HIC) at relativistic energies are a privileged tool for creating very hot and dense matter in a lab...

An algorithm to characterize collective motion is presented, with the introduction of “collective Lyapunov exponent”, as the orbital instability at a macroscopic level. By applying the algorithm to a globally coupled map, existence of low-dimensional collective chaos is confirmed, where the scale of (high-dimensional) microscopic chaos is separated from the macroscopic motion, and the scale app...

The renormalisation group equation for N -point correlation functions can be interpreted in a geometrical manner as an equation for Lie transport of amplitudes in the space of couplings. The vector field generating the diffeomorphism has components given by the βfunctions of the theory. It is argued that this simple picture requires modification whenever any one of the points at which the ampli...

While the distribution of spin periods of High Mass X–ray Binaries (HMXBs) spans more than four orders of magnitude (69 ms – 25 min), the few known X–ray pulsars accreting from very low mass companions (< 1 M ⊙) have very similar periods between 5.4 and 8.7 s. These pulsars display also several other similarities and they are probably members of a subclass of Low Mass X–ray Binaries (LMXBs) wit...

We present two different representations of (1, 1)-knots and study some connections between them. The first representation is algebraic: every (1, 1)-knot is represented by an element of the pure mapping class group of the twice punctured torus PMCG2(T ). Moreover, there is a surjective map from the kernel of the natural homomorphism Ω : PMCG2(T ) → MCG(T ) ∼= SL(2, Z), which is a free group of...
