Quantum Complexity Dynamics for Disjoint Subsystems
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +2
Quantum complexity has emerged as a natural probe of chaos, thermalization, and the black hole interior on timescales long after local observables have equilibrated. However, its t…
Sharp Transitions for Subsystem Complexity
Yale Fan, Nicholas Hunter-Jones, Andreas Karch +1
The circuit complexity of time-evolved pure quantum states grows linearly in time for an exponentially long time. This behavior has been proven in certain models, is conjectured to…
Models of quantum complexity growth
Fernando G. S. L. Brandão, Wissam Chemissany, Nicholas Hunter-Jones +2
The concept of quantum complexity has far-reaching implications spanning theoretical computer science, quantum many-body physics, and high energy physics. The quantum complexity of…
Spectral decoupling in many-body quantum chaos
Jordan Cotler, Nicholas Hunter-Jones
We argue that in a large class of disordered quantum many-body systems, the late time dynamics of time-dependent correlation functions is captured by random matrix theory, specific…
Chaos and random matrices in supersymmetric SYK
Nicholas Hunter-Jones, Junyu Liu
We use random matrix theory to explore late-time chaos in supersymmetric quantum mechanical systems. Motivated by the recent study of supersymmetric SYK models and their random mat…
On thermalization in the SYK and supersymmetric SYK models
Nicholas Hunter-Jones, Junyu Liu, Yehao Zhou
The eigenstate thermalization hypothesis is a compelling conjecture which strives to explain the apparent thermal behavior of generic observables in closed quantum systems. Althoug…
Chaos, Complexity, and Random Matrices
Jordan Cotler, Nicholas Hunter-Jones, Junyu Liu +1
Chaos and complexity entail an entropic and computational obstruction to describing a system, and thus are intrinsically difficult to characterize. In this paper, we consider time…
Consistency Conditions for an AdS/MERA Correspondence
Ning Bao, ChunJun Cao, Sean M. Carroll +4
The Multi-scale Entanglement Renormalization Ansatz (MERA) is a tensor network that provides an efficient way of variationally estimating the ground state of a critical quantum sys…
