Primordial black holes in non-linear perturbation theory [PDF]
, 2009 PhDThe thesis begins with a study of the origin of non-linear cosmological fluctuations. In particular, a class of models of multiple field inflation are considered, with specific reference to those cases in which the non-Gaussian correlation functions

Bound states of spinning black holes in five dimensions [PDF]
, 2017 We find and study supergravity BPS bound states of five-dimensional spinning black holes in asymptotically flat spacetime. These solutions follow from multi-string solutions in six-dimensional minimal supergravity and can be uplifted to F-theory or M ...

Black hole attractors and the entropy function in four- and five-dimensional N=2 supergravity [PDF]
, 2007 Extremal black holes in theories of gravity coupled to abelian gauge fields and neutral scalars, such as those arising in the low-energy description of compactifications of string theory on Calabi-Yau manifolds, exhibit the attractor phenomenon: on the ...

Impacts of Fermi Level Pinning at Hole‐Selective Contacts in CdSeTe/CdTe Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.Experimental measurements and SCAPS simulations consistently demonstrate dark–light J–V non‐superposition in CdSeTe/CdTe solar cells. The results indicate that donor‐like interface states at the ZnTe/CdTe contact pin the Fermi level, thereby producing a parasitic built‐in voltage that accounts for the observed non‐superposition (take‐off) behavior ...

Index saddle for supersymmetric F1-P black ring
Journal of High Energy PhysicsWe construct the index saddle for the supersymmetric F1-P black ring. Our construction proceeds by taking a supersymmetric limit of a non-supersymmetric doubly spinning F1-P black ring.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Higher-Derivative Corrected Black Holes: Perturbative Stability and Absorption Cross-Section in Heterotic String Theory [PDF]
, 2006 This work addresses spherically symmetric, static black holes in higher-derivative stringy gravity. We focus on the curvature-squared correction to the Einstein-Hilbert action, present in both heterotic and bosonic string theory.

From black strings to fundamental strings: non-uniformity and phase transitions
Journal of High Energy PhysicsWe discuss the transition between black strings and fundamental strings in the presence of a compact dimension, S z 1 $$ {\mathbbm{S}}_z^1 $$ . In particular, we study the Horowitz-Polchinski effective field theory in ℝ d × S z 1 $$ {\mathbb{R}}^d\times {
