| Research Abstract |
We construct a numerical tachyon vacuum solution with the highest accuracy in the world. As a result, we clarify that an identity-based solution can be regarded as the tachyon vacuum solution. In addition, we consider quantum effects in string field theories by using numerical and analytic methods. We show that a quantum effect should be vanished by some cancelation at the tachyon vacuum.
