Motivation • NR-CFT possess Schrodinger symmetry, NR version of conformal symmetry, and gravity duals were proposed. • Correct gravity dual solutions should geometrically realize a natural nonrelativistic limit taken in the field theory. • An example is the flow solution from AdS solution in UV to Schrodinger solution in IR • Can we find the geometric realization of this Holographic RG flow?
Nonrelativistic limit of field theory • (2+1) dimensional CFT with mass deformation. • Decompose relativistic fields into nonrelativistic particles and anti-particles. • Discards all anti-particles. • Restore and take the limit . • NR energy is redefined as

Schrodinger solution • Schrodinger symmetry is an extension of Galilean symmetry with particle number, dilatation, special conformal symmetry. • Geometric realization of Schrodinger algebra • Invariant under Schrodinger symmetry • Dilatation • Particle number symmetry • Focus on 5-dimensional Schrodinger solution. • Dual theory is (2+1)dim NR-CFT with U(1) global symmetry. • This U(1) global symmetry is identified as the shift of
Gravity Ansatz • A consistent KK truncation of D=11 supergravity. • : dual 1-form of Reeb vector where . • shift is dual to U(1) global rotation. • Choose : Skew-whiffing • Anti-M2 branes at the tip of 8-dimensional cone. • Asymptotic to : as • Far infrared : as : Kahler 2-form of Kahler-Einstein base .

Summary • Mass-deformed CFT has a natural nonrelativistic limit. • We studied the geometric realization of those limit. • We found a very simple class of the flow solutions from in UV to in IR. • We identified UV mass parameters in the dual mass-deformed CFT. • self-dual 4-form flux drives the flow.
