GUP Corrections to the Jaynes-Cummings Model
Kabir Khanna, Saurya Das
The Generalized Uncertainty Principle (GUP) is a modification of Heisenberg's Uncertainty Principle predicted by several theories of quantum gravity. In this work, we compute GUP c…
On the quantum origin of potentials
Saurya Das, Sourav Sur
The dynamics of a quantum particle is governed by its wavefunction, which in turn is determined by the classical potential to which it is subjected. However the wavefunction itself…
Generalized ladder operators for the perturbed harmonic oscillator
Pasquale Bosso, Saurya Das
In this paper, we construct corrections to the raising and lowering (i.e. ladder) operators for a quantum harmonic oscillator subjected to a polynomial type perturbation of any deg…
Relativistic particle in a box: Klein-Gordon vs Dirac Equations
Pedro Alberto, Saurya Das, Elias C. Vagenas
The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a corne…
Relativistic particle in a three-dimensional box
Pedro Alberto, Saurya Das, Elias C. Vagenas
We generalize the work of Alberto, Fiolhais and Gil and solve the problem of a Dirac particle confined in a 3-dimensional box. The non-relativistic and ultra-relativistic limits ar…
Rapid Data Search using Adiabatic Quantum Computation
Daria Ahrensmeier, Saurya Das, Randy Kobes +2
We show that by a suitable choice of time-dependent Hamiltonian, the search for a marked item in an unstructured database can be achieved in unit time, using Adiabatic Quantum Comp…
