Neutral positronium a charged particle
2010/11/30
Positronium is the atom-like bound state of an electron and its antiparticle the positron – and therefore has no net electrical charge. But physicists in the UK are scratching their heads after findin...
An alternative approach to exact wave functions for time-dependent coupled oscillator model of charged particle in variable magnetic field
time-dependent coupled oscillator model charged particle variable magnetic field
2010/11/4
A general treatment of the quantal time-dependent coupled oscillators in presence of the variable magnetic field is presented. The treatment is based on the use of an alternative canonical transforma...
Time-dependent coupled oscillator model for charged particle motion in the presence of a time varyingmagnetic field
charged particle motion unitary transformation
2010/11/4
The dynamics of time-dependent coupled oscillator model for the charged particle motion subjected to a time-dependent external magnetic field is investigated. We used canonical transformation approach...
Charged Particle--Image Interaction Near a Conducting Surface
Bohm-Pines Transformation Image Charge Plasmons
2010/4/12
The interaction of a bulk electron with conducting surfaces is studied by means of the Bohm-Pines transformation in the second quantization formalism. The effective interaction potentials are obtained...
