Marika's research interests include all aspects of string theory, gravitational physics and quantum field theory. In recent years much of her work has been focused on holographic dualities and their implications. Holography relates gravitational theories to theories without gravity in one less dimension and represents a completely new understanding of both gravity and the dual non-gravitational theories. Marika's work on holography encompasses both foundational issues (the holographic dictionary between gravity and gauge theory physics) and applications of holography to black hole physics, phenomenology and condensed matter systems.
On the foundational side, a primary goal in gravity/gauge theory dualities is to understand the precise holographic relationship between all gravity and gauge theory quantities. In a series of works Marika has established holographic dictionaries for spacetimes with various asymptotics, including those with running dilatons, Schrodinger geometries and Kaluza-Klein compactifications. More recently exploring to what extent a fluid/gravity correspondence can be established for vacuum Einstein solutions.
Turning now to implications of holography, gravity/gauge theory dualities are profoundly important in understanding black hole physics. Together with Kostas Skenderis, Marika showed that holography supports the idea that black hole microstates can be described by horizon-free, non-singular (but generically stringy) geometries. The black hole microstate proposal has the potential to shed new light on longstanding issues in black hole physics, such as the information loss paradox. Applied holography is becoming an interesting new tool for exploring strongly interacting systems, especially in condensed matter. Marika's works on non-relativistic holography are very relevant for understanding cold atom systems and superconductors, and the methodology of Kaluza-Klein holography is being used to develop more sophisticated models of d-wave superconductors.
