Time‐dependent density matrix renormalization group method for quantum dynamics in complex systems

WIREs Computational Molecular Science, 2022
The simulations of spectroscopy and quantum dynamics are of vital importance to the understanding of the electronic processes in complex systems, including the radiative/radiationless electronic relaxation relevant for optical emission, charge/energy ...

Quantum field simulator for dynamics in curved spacetime

Nature, 2022
In most cosmological models, rapid expansion of space marks the first moments of the Universe and leads to the amplification of quantum fluctuations1. The description of subsequent dynamics and related questions in cosmology requires an understanding of ...

Probing many-body dynamics on a 51-atom quantum simulator

Nature, 2017
Controllable, coherent many-body systems can provide insights into the fundamental properties of quantum matter, enable the realization of new quantum phases and could ultimately lead to computational systems that outperform existing computers based on ...

Quantum dynamics of simultaneously measured non-commuting observables

Nature, 2016
In quantum mechanics, measurements cause wavefunction collapse that yields precise outcomes, whereas for non-commuting observables such as position and momentum Heisenberg’s uncertainty principle limits the intrinsic precision of a state.

Recent Advances in Quantum Dynamics of Bimolecular Reactions.

Annual review of physical chemistry (Print), 2016
In this review, we survey the latest advances in theoretical understanding of bimolecular reaction dynamics in the past decade. The remarkable recent progress in this field has been driven by more accurate and efficient ab initio electronic structure ...
