Motion of a Test Particle in the Transverse space of Dp-Branes
Anindita Bhattacharjee, Ashok Das, Levi Greenwood +1
We investigate the motion of a test particle in higher dimensions due to the presence of extended sources like D-branes by studying the motion in the transverse space of the bra…
An alternative construction of the positive inner product for pseudo-Hermitian Hamiltonians: Examples
Ashok Das, L. Greenwood
This paper builds on our earlier proposal for construction of a positive inner product for pseudo-Hermitian Hamiltonians and we give several examples to clarify our method. We show…
An alternative construction of the positive inner product in non-Hermitian quantum mechanics
Ashok Das, L. Greenwood
Within the context of non-Hermitian quantum mechanics, we use the generators of eigenvectors of the Hamiltonian to construct a unitary inner product space. Such models have been of…
The structure of supersymmetry in symmetric quantum mechanics
D. Bazeia, Ashok Das, L. Greenwood +1
The structure of supersymmetry is analyzed systematically in symmetric quantum mechanical theories. We give a detailed description of supersymmetric systems associated…
