The fuzzy S^2 structure of M2-M5 systems in ABJM membrane theories
Horatiu Nastase, Constantinos Papageorgakis, Sanjaye Ramgoolam
We analyse the fluctuations of the ground-state/funnel solutions proposed to describe M2-M5 systems in the level-k mass-deformed/pure Chern-Simons-matter ABJM theory of multiple me…
Adding flavour to twistor strings
James Bedford, Constantinos Papageorgakis, Konstantinos Zoubos
Twistor string theory is known to describe a wide variety of field theories at tree-level and has proved extremely useful in making substantial progress in perturbative gauge theor…
On Time-dependent Collapsing Branes and Fuzzy Odd-dimensional Spheres
C. Papageorgakis, S. Ramgoolam
We study the time-dependent dynamics of a collection of N collapsing/expanding D0-branes in type IIA String Theory. We show that the fuzzy-S^3 and S^5 provide time-dependent soluti…
Noncommutative geometry, Quantum effects and DBI-scaling in the collapse of D0-D2 bound states
C. Papageorgakis, S. Ramgoolam, N. Toumbas
We study fluctuations of time-dependent fuzzy two-sphere solutions of the non-abelian DBI action of D0-branes, describing a bound state of a spherical D2-brane with N D0-branes. Th…
Large-small dualities between periodic collapsing/expanding branes and brane funnels
C. Papageorgakis, S. Ramgoolam
We consider space and time dependent fuzzy spheres arising in intersections in IIB string theory and collapsing D(2p)-branes in IIA string theory. In the case…
