Circuit Complexity in Topological Quantum Field Theory
Josiah Couch, Yale Fan, Sanjit Shashi
Quantum circuit complexity has played a central role in recent advances in holography and many-body physics. Within quantum field theory, it has typically been studied in a Lorentz…
Complexity of Mixed States in QFT and Holography
Elena Caceres, Shira Chapman, Josiah D. Couch +3
We study the complexity of Gaussian mixed states in a free scalar field theory using the 'purification complexity'. The latter is defined as the lowest value of the circuit complex…
Holographic Purification Complexity
Elena Cáceres, Josiah Couch, Stefan Eccles +1
We study holographic subregion complexity, and its possible connection to purification complexity suggested recently by Agón et al. In particular, we study the conjecture that subr…
Holographic Complexity and Volume
Josiah Couch, Stefan Eccles, Ted Jacobson +1
The previously proposed "Complexity=Volume" or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black ho…
Holographic complexity and non-commutative gauge theory
Josiah Couch, Stefan Eccles, Willy Fischler +1
We study the holographic complexity of noncommutative field theories. The four-dimensional noncommutative super Yang-Mills theory with Moyal algebra along two of th…
Noether charge, black hole volume, and complexity
Josiah Couch, Willy Fischler, Phuc H. Nguyen
In this paper, we study the physical significance of the thermodynamic volumes of AdS black holes using the Noether charge formalism of Iyer and Wald. After applying this formalism…
