D0-brane

Idea

The D-brane of dimension $0+1$ in type IIA string theory.

Properties

The worldline theory of a collection of D0-branes is supposed to be described by the BFSS matrix model.

Properties

Nonperturbative dynamics and M-theory

The non-perturbative limit of type IIA superstring theory is supposed to be M-theory compactified on a circle.

The degree-2 RR-field that the D0-brane is charged under, with local potential 1-form $A_1$ may be understood as the KK-field induced by this compactification, hence as one part of the field of gravity in 11-dimensional supergravity.

Under the duality between M-theory and type IIA string theory the M-wave becomes the black D0-brane under double dimensional reduction (Bergshoeff-Townsend 96).

One aspect of the M-theory conjecture is that type IIA string theory with a condensate of D0-branes behaves like a 10-dimensional theory that develops a further circular dimension of radius scaling with the density of D0-branes. (Banks-Fischler-Shenker-Susskind 97, Polchinski 99). See also (FSS 13, section 4.2).

Bound states

bound states/brane intersections involving D0-branes:

• D0-D2 brane bound state

• D0-D4 brane bound state

Relation to other branes

The electric-magnetic dual of the D0 is the D6-brane

electric-magnetic duality of D-branes/RR-fields in type II string theory:

electric charge	magnetic charge
D0-brane	D6-brane
D1-brane	D5-brane
