NEUTRINOLESS DOUBLE BETA DECAY: AN EXTREME CHALLENGE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Neutrino-less Double Beta Decay is the only known way to possibly resolve the nature of neutrino mass. The chances to cover the mass region predicted by the inverted hierarchy require a step forward in detector capability. ... -
NEUTRINOS AS COSMIC MESSENGERS IN THE ERA OF ICECUBE, ANTARES AND KM3NET
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Using neutrinos as cosmic messengers for observation of non-thermal processes in the Universe is a highly attractive and promising vision, which has been pursued in various neutrino telescope projects for more than two ... -
NEUTRINOS FROM ICARUS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Liquid Argon Time Projection Chambers are very promising detectors for neutrino and astroparticle physics due to their high granularity, good energy resolution and 3D imaging, allowing for a precise event reconstruction. ... -
NEW CONCEPT OF SOLVABILITY IN QUANTUM MECHANICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In quite a few recent quantum models one is allowed to make a given Hamiltonian H self-adjoint only after an ad hoc generalization of Hermitian conjugation, H†→H‡:= Θ −1H†Θ wherethe suitable operator Θ is called Hilbert-space ... -
Non-Hermitian Star-shaped Quantum Graphs
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)A compact review is given, and a few new numerical results are added to the recent studies of the q-pointed one-dimensional star-shaped quantum graphs. These graphs are assumed endowedwith certain specific, manifestly ... -
NON-THERMAL EMISSION FROM CATACLYSMIC VARIABLES: IMPLICATIONS ON ASTROPARTICLE PHYSICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation. It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, ... -
NOTE ON VERMA BASES FOR REPRESENTATIONS OF SIMPLE LIE ALGEBRAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We discuss the construction of the Verma basis of the enveloping algebra and of finite dimensional representations of the Lie algebra An. We give an alternate proof of so-called Verma inequalities to the one given in [1] ... -
Nuclear Fusion Effects Induced in Intense Laser-Generated Plasmas
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Deutered polyethylene (CD2)n thin and thick targets were irradiated in high vacuum by infrared laser pulses at 1015W/cm2 intensity. The high laser energy transferred to the polymer generates plasma, expanding in vacuum at ... -
On an Algorithm for Multiperiodic Words
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We consider an algorithm by Tijdeman and Zamboni constructing a word of length k thathas periods p1, . . . , pr, and the richest possible alphabet. We show that this algorithm can be easilystated and its correctness briefly ... -
ON RENORMALIZATION OF POISSON–LIE T-PLURAL SIGMA MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Covariance of the one-loop renormalization group equations with respect to Poisson–Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson–Lie sigma models with ... -
On Some Statistical Properties of GRBs with Measured Redshifts Having Peaks in Optical Light Curves
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We studied the subset of optical light curves of gamma-ray bursts with measured redshifts and well-sampled R band data that have clearly detected peaks. Among 43 such events, 11 are promptoptical peaks (P), coincident with ... -
On the Solvability of Some Partial Differential Inequality
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The Dulac criterion is a classical method for ruling out the existence of periodic solutions in planar differential equations. In this paper the applicability and therefore reversibility of this criterionis under consideration. -
OPERA HIGHLIGHTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The OPERA experiment is a long baseline neutrino oscillation experiment aimed at observing the νμ → ντ neutrino oscillation in the CERN neutrino to Gran Sasso beamline in the appearance mode by detecting the τ-decay. Here ... -
OUR GALACTIC CENTER – THE NEAREST BURNING DISK
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This short presentation will update my more than 25 years long attempts at understandingthe actions of the Central Engine at our Galactic Center. -
Particle Dynamics in the RMP Ergodic Layer under the Influence of Edge Plasma Turbulence
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The complex processes in edge tokamak plasma are affected (among others) both by resonant magnetic perturbation (RMP) and by plasma turbulence. RMP is nowadays considered to be a candidate for the mitigation of the ... -
