A Sotiropoulou (published as A. Sotiropoulou) is a Greek theoretical physicist who worked in the 1990s on deformed (q-)oscillator algebras, Lie-admissible formulations of quantum mechanics, and Santilli's isotopic and genotopic generalisations of relativity. Sotiropoulou published chiefly in collaboration with the Patras school of theoretical physics led by A. Jannussis, and with the Italian physicist R. Mignani.
Biography
Sotiropoulou's published work places her within the group of theoretical physicists centred on the Department of Physics of the University of Patras, Greece, and associated with A. Jannussis. Papers from this period appeared in mainstream journals such as Journal of Physics A: Mathematical and General and Modern Physics Letters A, as well as in the literature of the Institute for Basic Research and Hadronic Press circle at Palm Harbor, Florida, which promoted R. M. Santilli's hadronic mechanics.
Scientific contributions
Sotiropoulou's research addressed the algebraic foundations of quantum theory and their generalisations:
- Deformed oscillator algebras. With L. De Falco, A. Jannussis and R. Mignani, Sotiropoulou studied a q-boson oscillator algebra in which the deformation parameter q is allowed to be complex, publishing "q-Boson Oscillator Algebra with Complex Deformation Parameter" in Modern Physics Letters A 9 (1994), pp. 3331-3337.
- Quantum statistics of complex q-bosons. With P. Angelopoulou, S. Baskoutas, L. De Falco, A. Jannussis and R. Mignani, Sotiropoulou derived a real Planck distribution for a gas of q-bosons with complex deformation parameter, in "Real Planck distribution for a complex q-boson gas", Journal of Physics A: Mathematical and General 27 (1994), pp. L605-L609.
- Isotopic and genotopic relativity. With A. Jannussis, Sotiropoulou contributed "Isotopic and Genotopic Relativistic Theory" to the proceedings volume Frontiers of Fundamental Physics (edited by M. Barone and F. Selleri, Plenum Press, New York, 1994). The paper examines the isotopic and genotopic structure of relativistic theory through Santilli's isominkowskian spaces, in which the motion of particles and electromagnetic waves inside inhomogeneous and anisotropic physical media is represented by an altered space-time geometry. In the isotopic case the authors obtain a maximal speed of propagation of causal signals that is less than or equal to the speed of light in vacuum; in the genotopic case they introduce a Lie-admissible complex-time model giving complex interaction speeds and complex mass values. Using a small-distance derivative model they also derive a Lie-admissible form of the Wheeler-DeWitt equation and discuss the resulting asymmetry and inhomogeneity of space-time and the arrow of cosmological time.
- Quantum groups. With A. Jannussis, Sotiropoulou also investigated the connection between Lie-admissible and Lie-isotopic algebras and quantum groups, and the properties of the associated Heisenberg algebra representing position and momentum operators, in work presented at an international workshop on symmetry methods in physics held in memory of Professor Ya. A. Smorodinsky.
