It has been conjectured that an extremum of the tachyon potential of a bosonic D-brane represents the vacuum without any D-brane, and that various tachyonic lump solutions represent D-branes of lower dimension. We show that the tree level effective action of p-adic string theory, the expression for which is known exactly, provides an explicit realisation of these conjectures.

A Review on Tachyon Condensation in Open String Field Theories (2001, unknown): “A comparison between the world-volume theory of the solitonic q-brane and that of the Dirichlet q-brane was made in [123], and the fluctuations around the lump solutions were investigated in [124].”
On p-adic mathematical physics (2006, methodology): “Nonlocal scalar field theory [18, 19] for p-adic strings has occurred to be very instructive toy model [44, 45] for truncated string field theory models [46].”
On Exact Tachyon Potential in Open String Field Theory (2000, result): “% of accuracy. This approximation has been further improved and indeed it seems that the value of f approaches −1 (though there is no obvious small parameter expansion in level truncation method). In [6] the case of the p-adic strings was discussed. It was shown that the old results on the eﬀective ”
Effective tachyon dynamics in superstring theory (2000, background): “The p-adic string models [2], defined with a choice of prime number, describe tachyon dynamics with infinitely many spacetime derivatives and correctly show the dissappearance of on-shell dynamics at the stable vacuum.”
String Field Theory Around the Tachyon Vacuum (2000, methodology): “[φ] will be momentum independent and the higher order terms will have exponential dependence on the 13 momenta. This resembles the action of the p-adic string theory expanded around the tachyon vacuum[68, 35] after a momentum dependent rescaling of the tachyon ﬁeld. As in p-adic string theory we sha”

Classical solutions in string field theory around the tachyon vacuum (2001, background): “(This is precisely what happens in the case of p-adic string theory [29, 30, 31], background independent open string field theory [32, 33, 34, 35, 36, 37, 38, 39, 40], as well as non-commutative solitons [41, 42, 43].”
Boundary CFT construction of D-branes in vacuum string field theory (2001, methodology): “1) is very similar in spirit to the action of p-adic string theory [63, 64, 65].”
