Can the zero-point energy of the quantized harmonic oscillator be lower? Possible implications for the physics of "dark energy" and "dark matter"
H. A. Kastrup
Replacing the canonical pair q and p of the harmonic oscillator (HO) by the locally and symplectically equivalent pair angle phi and action variable I implies a qualitative change…
Wigner functions for the pair angle and orbital angular momentum: Possible applications in quantum information
H. A. Kastrup
The framework of Wigner functions for the canonical pair angle and orbital angular momentum, derived and analyzed in 2 recent papers [H. A. Kastrup, Phys.Rev. A 94, 062113(2016) an…
Wigner functions for angle and orbital angular momentum: Operators and dynamics
H. A. Kastrup
Recently a paper on the construction of consistent Wigner functions for cylindrical phase spaces S^1 x R, i.e. for the canonical pair angle and angular momentum, was presented (arX…
Wigner Functions for the Pair Angle and Orbital Angular Momentum
H. A. Kastrup
The problem of constructing physically and mathematically well-defined Wigner functions for the canonical pair angle and angular momentum is solved. While a key element for the con…
On the Advancements of Conformal Transformations and their Associated Symmetries in Geometry and Theoretical Physics
H. A. Kastrup
The historical developments of conformal transformations and symmetries are sketched: Their origin from stereographic projections of the globe, their blossoming in two dimensions w…
A New Look at the Quantum Mechanics of the Harmonic Oscillator
H. A. Kastrup
Classically the Harmonic Oscillator (HO) is the generic example for the use of angle and action variables phi in R mod 2 pi and I > 0. But the symplectic transformation (ϕ,I) to (q…
