Canonical vs. Grand Canonical Ensemble for Bosonic Gases under Harmonic Confinement [PDF]

open access: yesEntropy
We analyze the general relation between canonical and grand canonical ensembles in the thermodynamic limit. We begin our discussion by deriving, with an alternative approach, some standard results first obtained by Kac and coworkers in the late 1970s ...

Titration in Canonical and Grand-Canonical Ensembles

open access: yesThe Journal of Physical Chemistry B, 2023
We discuss problems associated with the notion of pH in heterogeneous systems. For homogeneous systems, standardization protocols lead to a well defined quantity, which although different from Sørensen's original idea of pH, is well reproducible and has become accepted as the measure of the ``hydrogen potential".

Microscopic interpretation of generalized entropy

open access: yesPhysics Letters B, 2023
Generalized entropy, that has been recently proposed, puts all the known and apparently different entropies like The Tsallis, the Rényi, the Barrow, the Kaniadakis, the Sharma-Mittal and the loop quantum gravity entropy within a single umbrella. However,

Grand canonical ensemble of weighted networks [PDF]

open access: yesPhysical Review E, 2019
The cornerstone of statistical mechanics of complex networks is the idea that the links, and not the nodes, are the effective particles of the system. Here we formulate a mapping between weighted networks and lattice gasses, making the conceptual step forward of interpreting weighted links as particles with a generalised coordinate.

Thermodynamics of structure-forming systems

open access: yesNature Communications, 2021
Structure-forming systems, such as chemical reaction networks, are usually described with the grand-canonical ensemble, but this may be inaccurate for small-sized systems.

Atomistic learning in the electronically grand-canonical ensemble

open access: yesnpj Computational Materials, 2023
A strategy is presented for the machine-learning emulation of electronic structure calculations carried out in the electronically grand-canonical ensemble.

On the Thermodynamics of Particles Obeying Monotone Statistics

open access: yesEntropy, 2023
The aim of the present paper is to provide a preliminary investigation of the thermodynamics of particles obeying monotone statistics. To render the potential physical applications realistic, we propose a modified scheme called block-monotone, based on a

Fluctuations in heavy ion collisions and global conservation effects [PDF]

open access: yesEPJ Web of Conferences, 2023
Subensemble is a type of statistical ensemble which is the generalization of grand canonical and canonical ensembles. The subensemble acceptance method (SAM) provides general formulas to correct the cumulants of distributions in heavy-ion collisions for ...

Stability and Hawking-Page-like phase transition of phantom AdS black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this work, we investigate the thermodynamic stability and phase structure of AdS black holes with either a Maxwell field (where we revisit past studies) or a phantom field.

Phase transition and heat engine efficiency of phantom AdS black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Phase transition and heat engine efficiency of phantom AdS black holes are investigated with peculiar properties found. In the non-extended phase space, we probe the possibility of T–S criticality in both the canonical ensemble and grand-canonical ...
