Geometric Aspects of Quantum Entanglement

<strong>Seminar of the School of Physical Sciences -------------------------------------------------</strong> Title : <strong>Geometric Aspects of Quantum Entanglement</strong> Speaker: <strong>Jyotirmoy Bhattacharya</strong> (Durham University, Durham) Date: <strong>September 17, 2015 </strong> <strong>Abstract: </strong>We will present a brief introduction to the basic concepts behind the gauge-gravity duality. In this context, we will go on to describe how the notion of entanglement entropy in quantum field theory, acquires a geometrical interpretation. Using such geometric techniques, we will explore some interesting properties of entanglement entropy, which has close resemblance with thermodynamics laws. We will then speculate on how these properties may be helpful to recast gravitational dynamics as an effective dynamics of quantum entanglement, via the gauge-gravity duality.
