Directed Percolation Criticality in Eternal Inflation
Justin Khoury, Sam S. C. Wong
False-vacuum eternal inflation can be described as a random walk on the network of vacua of the string landscape. In this paper we show that the problem can be mapped naturally to…
Non-linearities in the tidal Love numbers of black holes
Valerio De Luca, Justin Khoury, Sam S. C. Wong
Tidal Love numbers describe the linear response of a compact object under the presence of external tidal perturbations, and they are found to vanish exactly for black holes within…
Implications of the Weak Gravity Conjecture for Tidal Love Numbers of Black Holes
Valerio De Luca, Justin Khoury, Sam S. C. Wong
The Weak Gravity Conjecture indicates that extremal black holes in the low energy effective field theory should be able to decay. This criterion gives rise to non-trivial constrain…
Soft theorems for boosts and other time symmetries
Lam Hui, Austin Joyce, Ilia Komissarov +3
We derive soft theorems for theories in which time symmetries -- symmetries that involve the transformation of time, an example of which are Lorentz boosts -- are spontaneously bro…
Stability of Hairy Black Holes in Shift-Symmetric Scalar-Tensor Theories via the Effective Field Theory Approach
Justin Khoury, Toshifumi Noumi, Mark Trodden +1
Shift-symmetric Horndeski theories admit an interesting class of Schwarzschild-de Sitter black hole solutions exhibiting time-dependent scalar hair. The properties of these solutio…
Bayesian Reasoning in Eternal Inflation: A Solution to the Measure Problem
Justin Khoury, Sam S. C. Wong
Probabilities in eternal inflation are traditionally defined as limiting frequency distributions, but a unique and unambiguous probability measure remains elusive. In this paper, w…
Early-Time Measure in Eternal Inflation
Justin Khoury, Sam S. C. Wong
In a situation like eternal inflation, where our data is replicated at infinitely-many other space-time events, it is necessary to make a prior assumption about our location to ext…
Confinement on and Double-String Collapse
Mathew W. Bub, Erich Poppitz, Samuel S. Y. Wong
We study confining strings in supersymmetric Yang-Mills theory in the semiclassical regime on . Static quarks are expe…
Existence and Instability of Novel Hairy Black Holes in Shift-symmetric Horndeski Theories
Justin Khoury, Mark Trodden, Sam S. C. Wong
Shift-symmetric Horndeski theories admit an interesting class of Schwarzschild black hole solutions exhibiting time-dependent scalar hair. By making use of Lemaître coordinates, we…
Domain walls and deconfinement: a semiclassical picture of discrete anomaly inflow
Andrew A. Cox, Erich Poppitz, Samuel S. Y. Wong
We study the physics of quark deconfinement on domain walls in four-dimensional supersymmetric SU(N) Yang-Mills theory, compactified on a small circle with supersymmetric boundary…
Black Hole Hair from Scalar Dark Matter
Lam Hui, Daniel Kabat, Xinyu Li +2
We show that a black hole surrounded by scalar dark matter develops scalar hair. This is the generalization of a phenomenon pointed out by Jacobson, that a minimally coupled scalar…
Inflationary soft theorems revisited: A generalized consistency relation
Lam Hui, Austin Joyce, Sam S. C. Wong
We reconsider the derivation of soft theorems associated with nonlinearly-realized symmetries in cosmology. Utilizing the path integral, we derive a generalized consistency relatio…
Baryon Number Violating Scatterings in Laboratories
S. -H. Henry Tye, Sam S. C. Wong
Earlier estimates have argued that the baryon number violating scattering cross-section in the laboratory is exponentially small so it will never be observed, even for incoming 2-p…
Linking Light Scalar Modes with A Small Positive Cosmological Constant in String Theory
S. -H. Henry Tye, Sam S. C. Wong
Based on the studies in Type IIB string theory phenomenology, we conjecture that a good fraction of the meta-stable de Sitter vacua in the cosmic stringy landscape tend to have a v…
Holographic non-Gaussianities in general single-field inflation
Hiroshi Isono, Toshifumi Noumi, Gary Shiu +2
We use holographic techniques to compute inflationary non-Gaussianities for general single-field inflation, including models with a non-trivial sound speed. In this holographic app…
The Chern-Simons Number as a Dynamical Variable
S. -H. Henry Tye, Sam S. C. Wong
In the standard electroweak theory that describes nature, the Chern-Simons number associated with the vacua as well as the unstable sphaleron solutions play a crucial role in the b…
Bloch Wave Function for the Periodic Sphaleron Potential and Unsuppressed Baryon and Lepton Number Violating Processes
S. -H. Henry Tye, Sam S. C. Wong
For the periodic sphaleron potential in the electroweak theory, we find the one-dimensional time-independent Schrödinger equation with the Chern-Simons number as the coordinate, co…
Helical Inflation and Cosmic Strings
S. -H. Henry Tye, Sam S. C. Wong
Recent BICEP2 detection of low-multipole B-mode polarization anisotropy in the cosmic microwave background radiation supports the inflationary universe scenario and suggests a larg…
Statistical Distribution of the Vacuum Energy Density in Racetrack Kähler Uplift Models in String Theory
Yoske Sumitomo, S. -H. Henry Tye, Sam S. C. Wong
We study a racetrack model in the presence of the leading alpha'-correction in flux compactification in Type IIB string theory, for the purpose of getting conceivable de-Sitter vac…
