Transplanckian Dispersion Relation and Entanglement Entropy of Blackhole
Darwin Chang, Chong-Sun Chu, Feng-Li Lin
The quantum correction to the entanglement entropy of the event horizon is plagued by the UV divergence due to the infinitely blue-shifted near horizon modes. The resolution of thi…

String interactions and discrete symmetries of the pp-wave background
Chong-Sun Chu, Michela Petrini, Rodolfo Russo +1
Free string theory on the plane-wave background displays a discrete Z2 symmetry exchanging the two transverse SO(4) rotation groups. This symmetry should be respected also at the i…
