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 …

This review presents the effective temperature notion as defined from the deviations from the
equilibrium fluctuation–dissipation theorem in out-of-equilibrium systems with slow …

Membraneless compartments, also known as condensates, provide chemically distinct
environments and thus spatially organize the cell. A well-studied example of condensates is …

A paradigm shift in quantum thermometry is proposed. To date, thermometry has relied on
local estimation, which is useful to reduce statistical fluctuations once the temperature is very …

We consider the problem of estimating the temperature T of a very cold equilibrium sample.
The temperature estimates are drawn from measurements performed on a quantum …

It is known that temperature estimates of macroscopic systems in equilibrium are most
precise when their energy fluctuations are large. However, for nanoscale systems deviations …

The postulational basis of classical thermodynamics has been expanded to incorporate
equilibrium fluctuations. The main additional elements of the proposed thermodynamic …

Single-qubit thermometry presents the simplest tool to measure the temperature of thermal
baths with reduced invasivity. At thermal equilibrium, the temperature uncertainty is linked to …

We review two definitions of temperature in statistical mechanics, ${{T} _ {\text {B}}} $ and
${{T} _ {\text {G}}} $, corresponding to two possible definitions of entropy, ${{S} _ {\text {B}}} …

We present a joint theoretical and experimental analysis of thermorefractive noise in high-
quality-factor (Q), small-mode-volume (V) optical microcavities. Analogous to well-studied …
