The norm-1-property of a quantum observable
T. Heinonen, P. Lahti, J. -P. Pellonpaa +2
A normalized positive operator measure has the norm-1-property if $\no{E(X)}=1$ whenever . This property reflects the fact that the measurement outcome p…
UBVRI photopolarimetry of the long period eclipsing AM Herculis binary V1309
S. Katajainen, V. Piirola, G. Ramsay +6
We report simultaneous UBVRI photo-polarimetric observations of the long period (7.98 h) AM Her binary V1309 Ori. The length and shape of the eclipse ingress and egress varies from…
Cosmic vacuum and large-scale perturbations in the concordant model
Arthur D. Chernin
The evolution of cosmological large-scale perturbations is described in terms of the concordant model based on the recent discovery of cosmic vacuum. It is demonstrated that the pr…
Coexistence and Joint Measurability in Quantum Mechanics
Pekka Lahti
This talk is a survey of the question of joint measurability of coexistent observables and its is based on the monograph Operational Quantum Physics [1] and on the papers [2,3,4].
Vortex nucleation in Bose-Einstein condensates in time-dependent traps
Emil Lundh, J. -P. Martikainen, Kalle-Antti Suominen
Vortex nucleation in a Bose-Einstein condensate subject to a stirring potential is studied numerically using the zero-temperature, two-dimensional Gross-Pitaevskii equation. It is…
Two-fluid matter-quintessence FLRW models: energy transfer and the equation of state of the universe
A. Gromov, Yu. Baryshev, P. Teerikorpi
Recent observations support the view that the universe is described by a FLRW model with , , and at the present epoch. There are…
