Properties of the scale factor measure

- R. Bousso, Ben Freivogel, I-Sheng Yang
- Physics
- 27 August 2008

We show that in expanding regions, the scale factor measure can be reformulated as a local measure: Observations are weighted by integrating their physical density along a geodesic that starts in the… Expand

Coherent cascade conjecture for collapsing solutions in global AdS

- Ben Freivogel, I-Sheng Yang
- Physics
- 14 December 2015

We analyze the gravitational dynamics of a classical scalar field coupled to gravity in asymptotically AdS spacetime, which leads to black hole formation on the shortest nonlinear time scale for some… Expand

Casting shadows on holographic reconstruction

How to Run Through Walls: Dynamics of Bubble and Soliton Collisions

- J. Giblin, L. Hui, Eugene A. Lim, I-Sheng Yang
- Physics
- 19 May 2010

It has recently been shown in high resolution numerical simulations that relativistic collisions of bubbles in the context of a multivacua potential may lead to the creation of bubbles in a new… Expand

Boltzmann babies in the proper time measure

- R. Bousso, Ben Freivogel, I-Sheng Yang
- Physics
- 20 December 2007

After commenting briefly on the role of the typicality assumption in science, we advocate a phenomenological approach to the cosmological measure problem. Like any other theory, a measure should be… Expand

Eternal inflation: the inside story

- R. Bousso, Ben Freivogel, I-Sheng Yang
- Physics
- 14 June 2006

Motivated by the lessons of black hole complementarity, we develop a causal patch description of eternal inflation. We argue that an observer cannot ascribe a semiclassical geometry to regions… Expand

Position space analysis of the AdS (in)stability problem

- Fotios V. Dimitrakopoulos, Ben Freivogel, M. Lippert, I-Sheng Yang
- Physics
- 7 October 2014

A bstractWe investigate whether arbitrarily small perturbations in global AdS space are generically unstable and collapse into black holes on the time scale set by gravitational interactions. We… Expand

Missing top of the AdS resonance structure

- I-Sheng Yang
- Physics
- 5 January 2015

We study a massless scalar field in AdS(d+1) with a nonlinear coupling phi(N) and not limited to spherical symmetry. The free-field-eigenstate spectrum is strongly resonant, and it is commonly… Expand

Binary systems as resonance detectors for gravitational waves

- L. Hui, S. McWilliams, I-Sheng Yang
- Physics
- 11 December 2012

Gravitational waves at suitable frequencies can resonantly interact with a binary system, inducing changes to its orbit. A stochastic gravitational-wave background causes the orbital elements of the… Expand
