A Note on Classical Solution of Chaplygin-gas as D-brane
Naohisa Ogawa
The classical solution of bosonic d-brane in (d+1,1) space-time is studied. We work with light-cone gauge and reduce the problem into Chaplygin gas problem. The static equation is…
A Note on the scale symmetry and Noether current
Naohisa Ogawa
Usually we consider the symmetry of action as the symmetry of the theory, however, in the Keplar problem the scaling symmetry existing in equa tion of motion is not the ones for ac…
A Note on Gauge Principle and Spontaneous Symmetry Breaking in Classical Particle Mechanics
Naohisa Ogawa
The U(1) gauge field is usually induced from the gauge principle, that is, the extension of global U(1) phase transformation for matter field. However the phase itself is realized…
Embedding of Relativistic Particles and Spinor Natural-Frame
Naohisa Ogawa
Embedding of Klein-Gordon and Dirac particle onto Riemannian submanifold in higher dimensional Minkowski space is given by using Hamiltonian BRST formalism. Up to the ordering and…
Geometrically Induced Gauge Structure on Manifolds Embedded in a Higher Dimensional Space
Kanji Fujii, N. Ogawa, S. Uchiyama +1
We explain in a context different from that of Maraner the formalism for describing motion of a particle, under the influence of a confining potential, in a neighbourhood of an n-d…
Equivalence between Schwinger and Dirac schemes of quantization
N. Ogawa, K. Fujii, H. Miyazaki +2
This paper introduces the modified version of Schwinger's quantization method, in which the information on constraints and the choice of gauge conditions are included implicitly in…
Pedagogical Introduction to Hamiltonian BRST formalism
Naohisa Ogawa
Hamiltonian BRST formalism (FV formalism) includes many auxiliary fields without explanation. Its path-integration has a simple form by using BRST charge, but its construction is q…
Quantum Mechanical Embedding of Spinning Particle and Induced Spin-connection
Naohisa Ogawa
This paper introduces the way of the embedding of spinning particle quantum mechanically. Schrödinger equation on its submanifold obtains the gauge field as spin connection, and it…
