Adiabatic pumping and transport in the Sierpinski-Hofstadter model
Saswat Sarangi, Anne E. B. Nielsen
Topological phases have been reported on self-similar structures in the presence of a perpendicular magnetic field. Here, we present an understanding of these phases from a perspec…
Effect of coordination on topological phases on self-similar structures
Saswat Sarangi, Anne E. B. Nielsen
Topologically non-trivial phases have recently been reported on self-similar structures. Here, we investigate the effect of local structure, specifically the role of the coordinati…
Conifolds and Tunneling in the String Landscape
Pontus Ahlqvist, Brian R. Greene, David Kagan +3
We investigate flux vacua on a variety of one-parameter Calabi-Yau compactifications, and find many examples that are connected through continuous monodromy transformations. For th…
A Wrinkle in Coleman - De Luccia
Adam R. Brown, Saswat Sarangi, Benjamin Shlaer +1
Stringy effects on vacuum transitions are shown to include surprisingly large decay rates through very high potential barriers. This simple, yet counter-intuitive result will drast…
Vacuum Sampling in the Landscape during Inflation
Hooman Davoudiasl, Sash Sarangi, Gary Shiu
We consider the phenomenological consequences of sampling multiple vacua during inflation motivated by an enormous landscape. A generic consequence of this sampling is the formatio…
A Note on the Quantum Creation of Universes
Saswat Sarangi, S. -H. Henry Tye
We elucidate the nature of the correction to the Hartle-Hawking wavefunction presented in hep-th/ and hep-th/. The correction comes from the quantum fluctuation o…
