Chirping a two-photon transition in a multistate ladder RID C-2713-2008 RID A-7617-2010
(American Physical Society, 2007)
We consider a two-photon transition in a specific ladder system driven by a chirped laser pulse. In the weak field limit, we find that the excited state probability amplitude arises due to interference of multiple quantum ...
Role of noise operators on two-photon correlations in an extended coherent Raman medium
(American Physical Society, 2007)
An extended medium driven in a double Raman configuration generates Stokes and anti-Stokes fields that are described by coupled parametric oscillator equations with solutions that depend on input boundary operators and ...
Vacuum energy and repulsive Casimir forces in quantum star graphs
(American Physical Society, 2007)
Casimir pistons are models in which finite Casimir forces can be calculated without any suspect renormalizations. It has been suggested that such forces are always attractive, but we present several counterexamples, notably ...
