Description
Interest in entanglement entropy and its generalization Renyi entropy is growing due to its applications in a variety of fields in physics, from quantum computation and phase transitions to black hole physics and holography. In this talk I will discuss the effects of a small finite temperature on both measures of entanglement. The primary focus will be on calculating corrections for a free fermion on an n-sphere. Via conformal maps and a Boltzmann expansion of the density matrix, the corrections can be related to a specific two point function on a conical space. This work expands on previous work in Refs. arXiv:1407.1358 and arXiv:1411.6505.
