Schwinger-Dyson approach to light pseudoscalars
Dubravko Klabucar, Dalibor Kekez
We review briefly some of the successes of Schwinger-Dyson (SD) approach to the physics of quarks and hadrons, primarily light pseudoscalar mesons including eta and eta'. The main…
Phenomenological Schwinger-Dyson approach to eta-eta' mass matrix
Dalibor Kekez, Dubravko Klabucar
It is reviewed pedagogically how a very successful description of the eta-eta' mass matrix can be achieved in the consistently coupled Schwinger-Dyson and Bethe-Salpeter approach i…
Changes in the Hurst exponent of heartbeat intervals during physical activities
M. Martinis, A. Knežević, G. Krstačić +1
The fractal scaling properties of the heartbeat time series are studied in a controlled ergometric regime using the Hurst rescaled range R/S analysis. The long-time "memory effect"…
Is there chaos in the electron microscope?
D. Kunstelj, M. Martinis, A. Knežević
High-temperature superconductor has been investigated by the high-resolution electron microscope (HREM) and the photodensitometric technique in order…
Time Operator for a Quantum Singular Oscillator
M. Martinis, V. Mikuta
The problem of existence of a self-adjoint time operator conjugate to a Hamiltonian with SU(1,1) dynamical symmetry is investigated. In the space spanned by the eigenstates of the…
Quantum Computers, Discrete Space, and Entanglement
Mladen Pavicic
We consider algebras underlying Hilbert spaces used by quantum information algorithms. We show how one can arrive at equations on such algebras which define n-dimensional Hilbert s…
