Inter-dimensional Degeneracies in van der Waals Clusters and Quantum Monte Carlo Computation of Rovibrational States
Quantum Monte Carlo estimates of the spectrum of rotationally invariant
states of noble gas clusters suggest inter-dimensional degeneracy in and
spacial dimensions. We derive this property by mapping the Schr\"odinger
eigenvalue problem onto an eigenvalue equation in which appears as a
continuous variable. We discuss implications for quantum Monte Carlo and
dimensional scaling methods
Soliton Solutions and Conservation Laws for a Self-interacting Scalar Field in Theory
We calculate soliton solutions to the scalar field equation of motion that
arises for the 4th-order extended Lagrangian ( theory) in quantum
field theory using the extended hyperbolic tangent and the sine-cosine methods.
Using the former technique, ten complex soliton waves are obtained; we
graphically represent three of these profiles using density plots. In the
latter case, two real soliton solutions are obtained, of which, we demonstrate
the wave profile for the positive case. Using the multiplier method, we
calculate conservation laws in -, -, and -dimensions producing three, six, and ten conservation laws respectively.
Lastly, we reflect on the application of conservation laws in particle physics
and phenomenology.Comment: 19 pages, 2 figure
Conservation Laws for a Thermal Reservoir Model in Open Quantum Systems
We construct Lie point symmetries, a closed-form solution and conservation
laws using a non-Noetherian approach for a specific case of the
Gorini-Kossakowski-Sudarshan-Lindblad equation that has been recast for the
study of non-relativistic free particles in a thermal reservoir environment.
Conservation laws are constructed subsequently using the Ibragimov method via a
solution to the adjoint form of the equation of motion via its corresponding
scalaing symmetry. A general computational framework for obtaining all
conserved vectors is exhibited some triplets of conserved quantities are
calculated in full.Comment: 11 page
