Nonperturbative Stabilization of D-Instantons in the Bosonic IIB Matrix Model
Yu-An Chen, Hikaru Kawai, Henry Liao +1
We study the bosonic type IIB (IKKT) matrix model and the fate of the D-instanton positions , the diagonal components of the Hermitian matrices, whose one-loop effec…
Fermionic modes of D-instanton wormholes from broken local supersymmetry
H. Itoyama, Hikaru Kawai, Shoichi Kawamoto
In low-energy supergravity treatment of type IIB superstring on general D-instanton wormhole profiles in the bulk, we obtain non-vanishing scalar two-point functions in addition to…
General Actions of Extended Objects and Volume-Preserving Diffeomorphism
Pei-Ming Ho, Hikaru Kawai, Henry Liao
We consider actions that are general functions of the worldsheet/worldvolume metric and the induced metric for extended objects embedded in spacetime as Riemannian manifolds, areal…
General Relativity in IIB Matrix Model
Pei-Ming Ho, Hikaru Kawai, Harold C. Steinacker
The matrix models are non-perturbative formulations of string theory, from which many believe that spacetime arises. The matrix fluctuations around the spacetime thus created shoul…
UV Effects and Short-Lived Hawking Radiation: Alternative Resolution of Information Paradox
Pei-Ming Ho, Hikaru Kawai, Wei-Hsiang Shao
This chapter suggests an alternative solution to the black-hole information paradox by proposing that Hawking radiation ceases around the scrambling time due to trans-Planckian eff…
Stringy Spacetime Uncertainty Principle and a Modified Trans-Planckian Censorship Criterion
Robert Brandenberger, Pei-Ming Ho, Hikaru Kawai +1
We study the implications of the stringy space-time uncertainty relation (STUR) for inflationary cosmology. By demanding that no fluctuation modes that exit the Hubble radius are a…
