More on Effective Potentials for Revolving D-Branes

Satoshi Iso, Noriaki Kitazawa, Hikaru Ohta +1

We continue to investigate the effective potential between a pair of D $p$ -branes revolving around each other by using the technique of $partial modular transformation$ deve…

Revisiting weak measurement in light of thermodynamics

Daiki Ueda, Hikaru Ohta, Sumito Yokoo

We investigate a weak measurement described by a von Neumann type interaction $A^\otimes p^^{2}$ , where $A^$ is a system observable and $p^^{2}$ is a measurement po…

Dynamics of Revolving D-Branes at Short Distances

Satoshi Iso, Noriaki Kitazawa, Hikaru Ohta +1

We study the behavior of the effective potential between revolving D $p$ -branes at all ranges of the distance $r$ , interpolating $r ≫ l_{s}$ and $r ≪ l_{s}$ ( $l_{s}$ is the string len…

Effective Potential for Revolving D-branes

Satoshi Iso, Hikaru Ohta, Takao Suyama

We quantize an open string stretched between D0-branes revolving around each other. The worldsheet theory is analyzed in a rotating coordinate system in which the worldsheet fields…
