A Tale of Three. Tensionless strings and vacuum structure
Arjun Bagchi, Aritra Banerjee, Shankhadeep Chakrabortty +2
Within the premise of canonical quantisation, we re-examine the quantum structure of bosonic tensionless string theory. In the classical theory, the worldsheet metric degenerates a…
Local quantum energy conditions in non-Lorentz-invariant quantum field theories
Daniel Grumiller, Pulastya Parekh, Max Riegler
We provide the first example of local quantum energy conditions in quantum field theories that are not Lorentz invariant. We focus on field theories in two dimensions with infinite…
The tensionless path from closed to open strings
Arjun Bagchi, Aritra Banerjee, Pulastya Parekh
We reconsider the tensionless limit on bosonic closed string theory, where the 3d Bondi-Metzner-Sachs (BMS) algebra appears as symmetries on the worldsheet, as opposed to two copie…
Exotic Origins of Tensionless Superstrings
Arjun Bagchi, Aritra Banerjee, Shankhadeep Chakrabortty +1
A new type of tensionless superstring theory, called the Inhomogeneous tensionless superstring, has been recently introduced. This is characterised by a residual symmetry algebra o…
