3D Ising criticality with Platonic lattice superconducting qubits
Liyang Sui, Hong-Hao Song, Sainan Huai +13
The three-dimensional (3D) Ising model is a foundational model in statistical physics and critical phenomena, yet its analytical intractability has long impeded the precise determi…
Electronic Band Structure of Silicon Determined via a Variational Adiabatic Eigensolver: Theory and Experiment
Xingrui Liu, Liyang Sui, Tianqi Cai +11
This work addresses the critical challenge of excited-state preparation for semiconductor band structure calculations. We introduce a variational adiabatic eigensolver (VAE) protoc…
Thermal Pseudo-Entropy
Pawel Caputa, Bowen Chen, Tadashi Takayanagi +1
In this work, we develop a generalisation of the thermal entropy to complex inverse temperatures, which we call the thermal pseudo-entropy. We show that this quantity represents th…
Spread Complexity Rate as Proper Momentum
Pawel Caputa, Bowen Chen, Ross W. McDonald +2
We demonstrate a precise relation between the rate of complexity of quantum states excited by local operators in two-dimensional conformal field theories and the radial momentum of…
