Within the special issue “Classical and quantum plasmas: matter under extreme conditions” a series of papers are included that were presented at the international workshop “Plasma Physics and Astrophysics up to 2020 and beyond”. This meeting was held on October 7th–8th 2019 at the Physics Department of the Università della Calabria in Rende (Italy) and was organised by the Physics Department “Astrophysics, Geophysics and Plasma Group” in connection with the celebration of Pierluigi Veltri’s 70th birthday. The goal of this interdisciplinary workshop was to review some of the main achievements in plasma physics in the last five decades from laboratory to space and astrophysical plasmas and to discuss future developments. It was attended by experimentalists, theoreticians and by scientists involved in numerical plasma modelling with the aim of promoting the exchange of ideas and collaborations between different communities working on plasma physics in different contexts. The participants discussed fundamental physics aspects of fluid and plasma turbulence, of magnetic field line reconnection, of shock wave dynamics and of kinetic and nonlinear plasma phenomena highlighting new results and novel approaches, as well as exchanging ideas between different branches of plasma physics.

在特刊“经典和量子等离子体：极端条件下的物质”中，包括了一系列论文，这些论文在国际研讨会“直到2020年及以后的等离子体物理和天体物理学”上发表。此次会议于2019年10月7日至8日在意大利伦德卡拉布里亚大学的物理系举行，由物理系“天体物理学，地球物理学和等离子小组”组织，以庆祝Pierluigi Veltri诞辰70周年。这个跨学科讲习班的目的是回顾从实验室到太空和天体物理等离子在过去五年中在等离子体物理学中的一些主要成就，并讨论未来的发展。实验家参加了 理论家和参与数值等离子体建模的科学家，目的是促进在不同背景下从事等离子体物理研究的不同社区之间的思想交流和合作。与会者讨论了流体和等离子体湍流，磁场线重新连接，冲击波动力学以及动力学和非线性等离子体现象的基本物理方面，着重介绍了新的结果和新颖的方法，以及在等离子体物理的不同分支之间交换了思想。
