Avoiding fractional powers over the natural numbers

Lara Pudwell, Eric Rowland

We study the lexicographically least infinite $a / b$ -power-free word on the alphabet of non-negative integers. Frequently this word is a fixed point of a uniform morphism, or closel…

Scattering states of a vortex in the proximity-induced superconducting state at the interface of a topological insulator and an s-wave superconductor

Adam C. Durst

We consider an isolated vortex in the two-dimensional proximity-induced superconducting state formed at the interface of a three-dimensional strong topological insulator (TI) and a…

Entanglement Temperature and Perturbed AdS $_{3}$ Geometry

G. C. Levine, B. Caravan

In analogy to the first law of thermodynamics, the increase in entanglement entropy $δ S$ of a conformal field theory (CFT) is proportional to the increase in energy, $δ E$ , of the s…

Bosonization, cocycles, and the D1-D5 CFT on the covering surface

Benjamin A. Burrington, Amanda W. Peet, Ida G. Zadeh

We consider the D1-D5 CFT near the orbifold point, specifically the computation of correlators involving twist sector fields using covering surface techniques. As is well known, ce…

The Destruction of the Circumstellar Ring of SN 1987A

Claes Fransson, Josefin Larsson, Katia Migotto +23

We present imaging and spectroscopic observations with HST and VLT of the ring of SN 1987A from 1994 to 2014. After an almost exponential increase of the shocked emission from the…

Periodicity in the $p$ -adic valuation of a polynomial

Luis A. Medina, Victor H. Moll, Eric Rowland

For a prime $p$ and an integer $x$ , the $p$ -adic valuation of $x$ is denoted by $ν_{p} (x)$ . For a polynomial $Q$ with integer coefficients, the sequence of valuations $ν_{p} (Q (n))$ …

Scaling of Entanglement Entropy for the Heisenberg Model on Clusters Joined by Point Contacts

Barry A. Friedman, Gregory C. Levine

The scaling of entanglement entropy for the nearest neighbor antiferromagnetic Heisenberg spin model is studied computationally for clusters joined by a single bond. Bisecting the…

Mapping High-velocity H-alpha and Lyman-alpha Emission from Supernova 1987A

Kevin France, Richard McCray, Claes Fransson +12

We present new {\it Hubble Space Telescope} images of high-velocity H- $α$ and Lyman- $α$ emission in the outer debris of SN~1987A. The H- $α$ images are dominated by emission from hy…
