    Physical Basis for Minimal Time-Energy Uncertainty Relation.Y. S. Kim & Marilyn E. Noz - 1979 - Foundations of Physics 9 (5-6):375-387.
    A physical basis for the minimal time-energy uncertainty relation is formulated from basic high-energy hadronic properties such as the resonance mass spectrum, the form factor behavior, and the peculiarities of Feynman's parton picture. It is shown that the covariant oscillator formalism combines covariantly this time-energy uncertainty relation with Heisenberg's space-momentum uncertainty relation. A pictorial method is developed to describe the spacetime distribution of the localized probability density.

    Correspondence Between the Classical and Quantum Canonical Transformation Groups From an Operator Formulation of the Wigner Function.Leehwa Yeh & Y. S. Kim - 1994 - Foundations of Physics 24 (6):873-884.
    An explicit expression of the “Wigner operator” is derived, such that the Wigner function of a quantum state is equal to the expectation value of this operator with respect to the same state. This Wigner operator leads to a representation-independent procedure for establishing the correspondence between the inhomogeneous symplectic group applicable to linear canonical transformations in classical mechanics and the Weyl-metaplectic group governing the symmetry of unitary transformations in quantum mechanics.

    Standing Waves in the Lorentz-Covariant World.Y. S. Kim & Marilyn E. Noz - 2005 - Foundations of Physics 35 (7):1289-1305.
    When Einstein formulated his special relativity, he developed his dynamics for point particles. Of course, many valiant efforts have been made to extend his relativity to rigid bodies, but this subject is forgotten in history. This is largely because of the emergence of quantum mechanics with wave-particle duality. Instead of Lorentz-boosting rigid bodies, we now boost waves and have to deal with Lorentz transformations of waves. We now have some nderstanding of plane waves or running waves in the covariant picture, (...)

    Lorentz Deformation and the Jet Phenomenon.Y. S. Kim, Marilyn E. Noz & S. H. Oh - 1979 - Foundations of Physics 9 (11-12):947-954.
    It is shown that the Lorentz-deformation property discussed in previous papers is consistent with the hadronic jet phenomenon in high-energy production processes.

    Physical Principles in Quantum Field Theory and in Covariant Harmonic Oscillator Formalism.D. Han, Y. S. Kim & Marilyn E. Noz - 1981 - Foundations of Physics 11 (11-12):895-905.
    It is shown that both covariant harmonic oscillator formalism and quantum field theory are based on common physical principles which include Poincaré covariance, Heisenberg's space-momentum uncertainty relation, and Dirac's “C-number” time-energy uncertainty relation. It is shown in particular that the oscillator wave functions are derivable from the physical principles which are used in the derivation of the Klein-Nishina formula.

    Lorentz Deformation and the Jet Phenomenon. II. Explanation of the Nearly Constant Average Jet Transverse Momentum.S. H. Oh, Y. S. Kim & Marilyn E. Noz - 1980 - Foundations of Physics 10 (7-8):635-639.
    It is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.
