Journal of Statistical Mechanics: Theory and Experiment

Journal of Statistical Mechanics: Theory and Experiment (JSTAT) is a peer-reviewed physics journal published by IOP Publishing on behalf of SISSA Medialab, the publishing company of the International School for Advanced Studies in Trieste. Created in 2004 as an electronic-only title, it covers statistical physics in its widest sense and recorded a 2025 Journal Impact Factor of 1.9.《统计力学杂志（理论与实验）》（JSTAT）是一份同行评议物理期刊，由 IOP Publishing 代表里雅斯特国际高等研究学院的出版机构 SISSA Medialab 出版。该刊 2004 年以纯电子版形式创刊，覆盖最广义的统计物理，2025 年期刊影响因子为 1.9。

Scope

• Statistical physics sets the remit, and the editors read the field broadly enough to include mathematics, biology and computer science whenever a collective or probabilistic argument carries the paper.统计物理界定了收稿范围，编辑对领域的理解相当宽泛，只要论文以集体行为或概率论证为核心，数学、生物与计算机科学的稿件都在视野之内。
• Quantum statistical physics forms the largest single block, taking in quantum spin systems, entanglement entropy, quantum quenches and the thermalisation of isolated many-body systems.量子统计物理是最大的一个板块，涉及量子自旋系统与纠缠熵，也讨论量子淬火以及孤立多体系统的热化。
• Exactly solved models and integrable systems remain a signature strength, with papers on lattice models, Bethe ansatz solutions, conformal field theory and integrable quantum chains.可精确求解的模型与可积系统一直是该刊的招牌，涵盖格点模型与 Bethe 拟设解，也涉及共形场论与可积量子链。
• Classical statistical mechanics covers the equilibrium thermodynamics of fluids, lattice gases, interface models and the rigorous theory of phase transitions.经典统计力学部分讨论流体的平衡热力学与格点气体，也处理界面模型以及相变的严格理论。
• Nonequilibrium behaviour is treated at length, from driven diffusive systems and fluctuation theorems to anomalous transport, ageing and slow relaxation in glassy matter.非平衡行为得到充分讨论，从驱动扩散系统与涨落定理，到反常输运、老化以及玻璃态物质中的慢弛豫。
• Disordered systems attract steady traffic, including spin glasses, random matrices, percolation, replica methods and the statistical mechanics of random constraint satisfaction.无序系统吸引稳定的投稿，包括自旋玻璃与随机矩阵，也接纳渗流、复本方法以及随机约束满足问题的统计力学。
• Critical phenomena and the renormalisation group appear both through field-theoretic calculations and through high-precision simulation of universal amplitude ratios and critical exponents.临界现象与重整化群既通过场论计算处理，也借助普适振幅比与临界指数的高精度模拟来研究。
• Interdisciplinary statistical mechanics has grown into a distinct stream, covering complex networks, opinion dynamics, urban and financial data, and the statistics of ranking and search.跨学科统计力学已发展成独立的方向，覆盖复杂网络与舆论动力学，也处理城市与金融数据，以及排序与搜索的统计规律。
• Biological modelling and information theory sit together in the scope, with work on gene regulation, neural coding, collective animal behaviour, evolution and inference from noisy data.生物建模与信息论在收稿范围中并列，涉及基因调控与神经编码，也讨论动物集群行为、演化以及从含噪数据中做推断的工作。
• Computational methodology is welcome in its own right, and Monte Carlo algorithms, cluster updates, tensor-network contractions and machine-learning ansätze appear regularly.计算方法本身也受到欢迎，Monte Carlo 算法与集团更新经常出现，张量网络收缩与机器学习拟设同样不少。
• Experiment earns explicit room in the title and in practice, especially granular media, colloidal suspensions, active matter, cold atoms and fluid turbulence.实验在刊名与实践中都占有明确位置，颗粒物质与胶体悬浮液尤为常见，活性物质、冷原子与流体湍流同样不少。
• Mathematical physics papers are accepted when a statistical-mechanical question drives them, for instance large-deviation principles, stochastic geometry or the scaling limits of interacting particle systems.若统计力学问题构成主线，数学物理论文也会被接受，例如大偏差原理、随机几何或相互作用粒子系统的标度极限。
• Statistical inference and machine learning have moved close to the core, with phase transitions in learning, message passing and the thermodynamics of training treated as statistical-mechanical problems.统计推断与机器学习已靠近核心，学习中的相变、消息传递以及训练过程的热力学被当作统计力学问题处理。

History

• The journal was created in 2004 by the International School for Advanced Studies and IOP Publishing, and it has appeared under that joint arrangement ever since.该刊 2004 年由国际高等研究学院与 IOP Publishing 共同创办，此后一直沿用这一合作安排。
• The launch followed the pattern of two sister titles run from the same Trieste office, the Journal of High Energy Physics (1997) and the Journal of Cosmology and Astroparticle Physics (2003).创刊沿用了同一编辑部两份姊妹刊的做法，即 1997 年创办的《高能物理杂志》与 2003 年创办的《宇宙学与天体粒子物理杂志》。
• No print run was ever planned, so the title carries a single electronic ISSN, 1742-5468, and every article exists only in digital form.该刊从未计划印刷版，只申请了一个电子 ISSN，即 1742-5468，所有文章仅以数字形式存在。
• Editorial handling stayed with SISSA in Trieste while production, hosting and subscription administration moved to IOP in Bristol.编辑事务留在的里雅斯特的 SISSA，制作、托管与订阅管理则交由布里斯托的 IOP 承担。
• The imprint now states that the journal is published on behalf of SISSA Medialab, the school's own publishing company, rather than the school itself.现行版本说明写明，该刊由 SISSA 自设的出版公司 SISSA Medialab 委托出版，署名主体为该公司。
• One volume corresponds to one calendar year, and citations use an article number instead of a page range, for example J. Stat. Mech. (2024) 113203.一卷对应一个日历年，引用时使用文章编号而非页码，例如 J. Stat. Mech. (2024) 113203。
• Publication is continuous. Accepted manuscripts are posted individually and later gathered into the monthly issues of the running volume, so nothing waits for a full issue to be compiled.出版过程是连续的。录用稿件逐篇上线，随后归入当年卷的月度期次，没有稿件需要等到整期凑齐。
• From the first volume the promised turnaround has been counted in weeks, with accepted papers typeset and posted soon after acceptance.从第一卷起，承诺的处理周期就以周计，录用论文在接收后不久即完成排版并上线。
• Special issues have been a fixture, usually organised around a workshop or a focused theme proposed to the editorial board.特刊是长期保留的栏目，通常围绕某次研讨会或提交编委会的专题构想组织。
• Topical review articles were added later, giving the field long survey pieces alongside the shorter research papers that make up most of each issue.专题综述文章在后来加入，为领域提供篇幅较长的综述，与构成每期主体的短篇研究论文并存。
• Because the archive was born digital, the whole run from 2004 is available through IOPscience, with no scanned backfile and no gaps in the record.由于档案自始即为数字形式，2004 年以来的全部内容都可在 IOPscience 上查阅，没有扫描的过刊，也没有记录缺口。
• Access is mixed. Most papers sit behind a subscription, authors may pay to make an individual article open access, and the gold share reached 34.6 percent in the 2025 data.访问模式是混合的。多数论文位于订阅墙后，作者可付费使单篇文章开放获取，2025 年数据中的金色开放获取比例为 34.6%。
• Impact factors have drifted downward in the present decade, from 2.234 in 2022 to 2.2 in 2023 and 1.9 in both 2024 and 2025.影响因子在本十年缓慢下行，2022 年为 2.234，2023 年为 2.2，2024 年与 2025 年均为 1.9。
• The 2025 five-year impact factor stands at 2.1, the Journal Citation Indicator at 0.63, and the title publishes roughly 225 articles a year with a cited half-life of 11.4 years.2025 年的五年影响因子为 2.1，期刊引文指标为 0.63，年发文约 225 篇，被引半衰期为 11.4 年。
• In the 2025 Journal Citation Reports it ranks 114 of 172 in Mechanics and 24 of 61 in Physics, Mathematical.在 2025 年期刊引证报告中，该刊在力学类 172 种期刊中列第 114 位，在数学物理类 61 种期刊中列第 24 位。

• The panel is deliberately international, with members drawn from institutions in Italy, France, the United States and Israel.编委构成具有明显的国际分布，成员来自意大利、法国、美国与以色列的机构。
• Prospective authors submit through the SISSA editorial office, and a manuscript reaches the director whose panel matches the subject before any referee is approached.作者经 SISSA 编辑部投稿，稿件在送审之前先到达学科对口的小组负责人手中。
• Refereeing follows the usual single-blind practice of physics journals. Reports stay confidential and the referees know who wrote the paper.审稿遵循物理期刊常见的单盲做法。审稿报告保密，审稿人知晓作者身份。
• Desk decisions come quickly when a manuscript looks better suited to a specialised condensed-matter or mathematics title.若稿件更适合专门的凝聚态或数学期刊，编辑会迅速作出拒稿决定。
• Special issues are steered by guest editors who work with the relevant scientific director, and the call for papers is posted on the journal site.特刊由客座编辑在相关科学主任的配合下主持，征稿通知发布在期刊网站上。
• Authors who are unsure of the fit can write to the editorial office, although the reply is advisory and does not replace peer review.对收稿范围没有把握的作者可以致信编辑部，答复仅供参考，不能替代同行评议。
• The board keeps a working balance between permanent scientific directors and ad hoc referees, so that a submission on an unusual topic still reaches an expert reader.编委会在常任科学主任与临时审稿人之间保持平衡，使冷门主题的稿件也能送到行家手中。
