(A)Symmetric Complexity and the Quantum Mpemba Effect
Cameron Beetar, Jeff Murugan, Hendrik J. R. van Zyl
The Quantum Mpemba Effect (QME) -- the counter-intuitive phenomenon where states further from equilibrium can relax faster than those closer to it -- challenges standard expectatio…
From Symmetry to Structure: Gauge-Invariant Operators in Multi-Matrix Quantum Mechanics
Robert de Mello Koch, Minkyoo Kim, Hendrik J. R. Van Zyl
Recently the algebraic structure of gauge-invariant operators in multi-matrix quantum mechanics has been clarified: this space forms a module over a freely generated ring. The ring…
On Complexity and Duality
Jeff Murugan, Zayd Pandit, Hendrik J. R. van Zyl
We explore the relationship between complexity and duality in quantum systems, focusing on how local and non-local operators evolve under time evolution. We find that non-local ope…
Reconstructing the spacetime dual to a free matrix
Robert de Mello Koch, Pratik Roy, Hendrik J. R. Van Zyl
In this paper we consider the collective field theory description of the singlet sector of a free matrix field in 2+1 dimensions. This necessarily involves the study of -local c…
Emergent Yang-Mills theory
Robert de Mello Koch, Jia-Hui Huang, Minkyoo Kim +1
We study the spectrum of anomalous dimensions of operators dual to giant graviton branes. The operators considered belong to the su sector of super Yang-Mills t…
Structure constants of heavy operators in ABJM/ABJ Theory
Gaoli Chen, Robert de Mello Koch, Minkyoo Kim +1
Efficient and powerful approaches to the computation of correlation functions involving determinant, sub-determinant and permanent operators, as well as traces, have recently been…
Absorption of closed strings by giant gravitons
Gaoli Chen, Robert de Mello Koch, Minkyoo Kim +1
A new approach to the computation of correlation functions involving two determinant operators as well as one non-protected single trace operator has recently been developed by Jia…
Spectral Form Factor as an OTOC Averaged over the Heisenberg Group
Robert de Mello Koch, Jia-Hui Huang, Chen-Te Ma +1
We prove that in bosonic quantum mechanics the two-point spectral form factor can be obtained as an average of the two-point out-of-time ordered correlation function, with the aver…
