The One-loop Open Superstring Massless Five-point Amplitude with the Non-Minimal Pure Spinor Formalism

Carlos R. Mafra, Christian Stahn

We compute the massless five-point amplitude of open superstrings using the non-minimal pure spinor formalism and obtain a simple kinematic factor in pure spinor superspace, which…

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…

Non-commutative Supersymmetric Quantum Mechanics

Ashok Das, H. Falomir, J. Gamboa +1

General non-commutative supersymmetric quantum mechanics models in two and three dimensions are constructed and some two and three dimensional examples are explicitly studied. The…

Thermal instability in a gravity-like scalar theory

F. T. Brandt, Ashok Das, J. Frenkel

We study the question of stability of the ground state of a scalar theory which is a generalization of the phi^3 theory and has some similarity to gravity with a cosmological const…

Proper acceleration, geometric tachyon and dynamics of a fundamental string near D branes

Ashok Das, Sudhakar Panda, Shibaji Roy

We present a detailed analysis of our recent observation that the origin of the geometric tachyon, which arises when a D-brane propagates in the vicinity of a stack of coinciden…

A Relativistic Wave Equation for the Skyrmion

S. G. Rajeev

We propose a relativistically invariant wave equation for the Skyrme soliton. It is a differential equation on the space which is invariant under the Lorentz gr…
