Symmetry-enhanced discontinuous phase transition in a two-dimensional quantum magnet
A phase transition often implies symmetry breaking in the system. However, an unconventional first-order phase transition is predicted, where higher-order symmetry than that of the underlying Hamiltonian emerges exactly at the phase boundary.

🌡 Temperature in and out of equilibrium: a review of concepts, tools and attempts
https://arxiv.org/pdf/1711.03770
A. Puglisi, A. Sarracino, A. Vulpiani
(Submitted on 10 Nov 2017)
Abstract:
We review the general aspects of the concept of temperature in equilibrium and non-equilibrium statistical mechanics. Although temperature is an old and well-established notion, it still presents controversial facets. After a short historical survey of the key role of temperature in thermodynamics and statistical mechanics, we tackle a series of issues which have been recently reconsidered. In particular, we discuss different definitions and their relevance for energy fluctuations. The interest in such a topic has been triggered by the recent observation of negative temperatures in condensed matter experiments. Moreover, the ability to manipulate systems at the micro and nano-scale urges to understand and clarify some aspects related to the statistical properties of small systems (as the issue of temperature's "fluctuations"). We also discuss the notion of temperature in a dynamical context, within the theory of linear response for Hamiltonian systems at equilibrium and stochastic models with detailed balance, and the generalised fluctuation-response relations, which provide a hint for an extension of the definition of temperature in far-from-equilibrium systems. To conclude we consider non-Hamiltonian systems, such as granular materials, turbulence and active matter, where a general theoretical framework is still lacking.

So, How Do You Get a Job? | Institute for Mathematics and its Applications
I was late. I only decided to find a job in industry in the 4th year of my graduate study even though I never had a job outside of academia. The one question that I kept asking was: how do you get a job? It was scary because I did't know what to do. But I…
🔸What does it mean to be central in a complex network? Nobody knows, b/c there are many distinct ways of being central. Our recent work, led by our great @GiuliaTtt, attacks the problem from a #stats perspective: the most central node is the median of the network.
