1 Determining eigenstates and thermal states on a quantum computer using quantum imaginary time evolution 2019-11-12             

HTML   |   详细信息   |  

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0704-4

The quantum imaginary time evolution and Lanczos algorithms offer a resource-efficient way to compute ground or excited states of target Hamiltonians on quantum computers. This offers promise for quantum simulation on near-term noisy devices.

2 Imaging emergent heavy Dirac fermions of a topological Kondo insulator 2019-11-12

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0700-8

High-energy-resolution spectroscopic measurements performed on the Kondo insulator SmB6 reveal the presence of correlation-driven heavy surface states—the heavy Dirac fermions—and shed light on the search for the correlated topological materials.

3 The energy cost and optimal design for synchronization of coupled molecular oscillators 2019-11-12             

HTML   |   详细信息   |  

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0701-7

The energy cost for the synchronization of biochemical oscillators is determined under general conditions. This framework reveals a relationship between the KaiC ATPase activity and the synchronization of the KaiC hexamers.

4 Light-induced charge density wave in LaTe3 2019-11-12             

HTML   |   详细信息   |  

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0705-3

Short pulses of light shift the balance between two competing charge density wave phases, allowing the weaker one to manifest transiently while suppressing the stronger one. This shows that competing phases can be tuned in a non-equilibrium setting.

5 Cooling with imaginary time 2019-11-12             

HTML   |   详细信息   |  

Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0709-z

Finding ground states of given Hamiltonians is crucial for quantum simulation — a promising application of quantum computers. An algorithm now finds these states using minimal resources, making it implementable in near-term noisy devices.

6 Order! Order!! 2019-11-05             

HTML   |   详细信息   |  

Nature Physics, Published online: 04 November 2019; doi:10.1038/s41567-019-0714-2

The ferromagnetism of iron has been known for millennia. Now a rotational form of spontaneous crystallographic ordering has been discovered. This touches upon fundamental questions about the relation between symmetry, structure and order in matter.

7 Leibniz’s principle of indistinguishability 2019-11-05

Nature Physics, Published online: 04 November 2019; doi:10.1038/s41567-019-0711-5

Leibniz’s principle of indistinguishability

8 Observation of a ferro-rotational order coupled with second-order nonlinear optical fields 2019-11-05             

HTML   |   详细信息   |  

Nature Physics, Published online: 04 November 2019; doi:10.1038/s41567-019-0695-1

The authors use optical spectroscopy to show that RbFe(MoO4)2 hosts a ferro-rotational phase. This is the final form of ferroic order to be observed.

9 Transient wave function twist 2019-11-05             

HTML   |   详细信息   |  

Nature Physics, Published online: 04 November 2019; doi:10.1038/s41567-019-0708-0

An experiment using ultrafast light pulses demonstrates how to induce a transient chiral electron state in a trivial semimetal.

10 A supreme achievement 2019-11-05             

HTML   |   详细信息   |  

Nature Physics, Published online: 04 November 2019; doi:10.1038/s41567-019-0721-3

The demonstration of a quantum computational advantage is a milestone worth celebrating.
