Developments on the Jordan-Schwinger construction and contraction for the
R. Kullock
The contraction and Jordan-Schwinger construction connect the and the heisenberg algebra, going in oposite directions. This persists in the q-deformed cases, but in a sligh…
On the physics of the hydrogen atom
P. G. Castro, R. Kullock
In this work we investigate the -deformation of the dynamical symmetry of the hydrogen atom using the theory of the quantum group . We derive the energy spectru…
Snyder Noncommutativity and Pseudo-Hermitian Hamiltonians from a Jordanian Twist
P. G. Castro, R. Kullock, F. Toppan
Nonrelativistic quantum mechanics and conformal quantum mechanics are deformed through a Jordanian twist. The deformed space coordinates satisfy the Snyder noncommutativity. The re…
Noncommutative oscillators from a Hopf algebra twist deformation. A first principles derivation
P. G. Castro, B. Chakraborty, R. Kullock +1
Noncommutative oscillators are first-quantized through an abelian Drinfel'd twist deformation of a Hopf algebra and its action on a module. Several important and subtle issues maki…
Virtual Processes and Superradiance in Spin-Boson Models
M. Aparicio Alcalde, R. Kullock, N. F. Svaiter
We consider spin-boson models composed by a single bosonic mode and an ensemble of identical two-level atoms. The situation where the coupling between the bosonic mode and the…
