RG studies of scalar-field models of long-range interactions
Alfio M. Bonanno, S. R. Haridev, Gaurav Narain
In this work we studies the long-range interactions in non-gravitational field theories and their behaviour in the deep infrared. To model such effects, we consider a nonlocal scal…
Bulk-boundary dictionary for a non local bulk field
Nirmalya Kajuri, Gaurav Narain
AdS/CFT correspondence gives us a bulk-boundary dictionary between CFT operators and local fields in the bulk. Can a bulk-boundary dictionary exist for a non local bulk field? In t…
Non-locality effect on the entanglement entropy in deSitter
Gaurav Narain, Hai-Qing Zhang
We investigate the effect of infrared non-locality on the entanglement between two causally separated open-charts in the deSitter space-time. Inspired by the work of Maldacena and…
Entanglement entropy of non-local theories in AdS
Gaurav Narain, Nirmalya Kajuri
We investigate the effect of non-locality on entanglement entropy in anti-de Sitter space-time. We compute entanglement entropy of a nonlocal field theory in anti-de Sitter space-t…
Non-local scalar field on deSitter and its infrared behaviour
Gaurav Narain, Nirmalya Kajuri
We investigate free non-local massless and massive scalar field on deSitter (dS) space-time. We compute the propagator for the non-local scalar field for the corresponding theories…
Non-locality and late-time cosmic acceleration from an ultraviolet complete theory
Gaurav Narain, Tianjun Li
A local phenomenological model that reduces to a non-local gravitational theory giving dark energy is proposed. The non-local gravity action is known to fit the data as well as …
