Conformal Symmetry, Rindler Space and The AdS/CFT Correspondence
Prasant Samantray, T. Padmanabhan
Field theories in black hole spacetimes undergo dimensional reduction near horizon (in the Rindler limit) to two dimensional conformal field theories. We investigate this enhanceme…
Structural Aspects Of Gravitational Dynamics And The Emergent Perspective Of Gravity
T. Padmanabhan
I describe several conceptual aspects of a particular paradigm which treats the field equations of gravity as emergent. These aspects are related to the features of classical gravi…
Complex Effective Path: A Semi-Classical Probe of Quantum Effects
Suprit Singh, T. Padmanabhan
We discuss the notion of an effective, average, quantum mechanical path which is a solution of the dynamical equations obtained by extremizing the quantum effective action. Since t…
Zero-point length from string fluctuations
Michele Fontanini, Euro Spallucci, T. Padmanabhan
One of the leading candidates for quantum gravity, viz. string theory, has the following features incorporated in it. (i) The full spacetime is higher dimensional, with (possibly)…
A Viable Cosmology with a Scalar Field Coupled to the Trace of the Stress-Tensor
M. Sami, T. Padmanabhan
We study the cosmological evolution of a scalar field that couples to the trace of energy momentum tensor of all the fields (including itself). In the case of a shallow…
Can the clustered dark matter and the smooth dark energy arise from the same scalar field ?
T. Padmanabhan, T. Roy Choudhury
Cosmological observations suggest the existence of two different kinds of energy densities dominating at small ( Mpc) and large ( Mpc) scales. The dar…
