Loop expansion in Yang-Mills thermodynamics [PDF]
, 2006 We argue that a selfconsistent spatial coarse-graining, which involves interacting (anti)calorons of unit topological charge modulus, implies that real-time loop expansions of thermodynamical quantities in the deconfining phase of SU(2) and SU(3) Yang ...

Reconstruction of $f(T)$ gravity: Rip cosmology, finite-time future singularities and thermodynamics
, 2012 We demonstrate that there appear finite-time future singularities in $f(T)$ gravity with $T$ being the torsion scalar. We reconstruct a model of $f(T)$ gravity with realizing the finite-time future singularities.

Dynamics of energy transport and entropy production in ac-driven quantum electron systems [PDF]
, 2016 We analyze the time-resolved energy transport and the entropy production in ac-driven quantum coherent electron systems coupled to multiple reservoirs at finite temperature.

On the efficiency at maximum cooling power
, 2013 The efficiency at maximum power (EMP) of heat engines operating as generators is one corner stone of finite-time thermodynamics, the Curzon-Ahlborn efficiency $\eta_{\rm CA}$ being considered as a universal upper bound.

Quantum Confinement and Negative Heat Capacity [PDF]
, 2013 Thermodynamics dictates that the specific heat of a system is strictly non-negative. However, in finite classical systems there are well known theoretical and experimental cases where this rule is violated, in particular finite atomic clusters.

Geometric Optimisation of Quantum Thermodynamic Processes
Entropy, 2020 Differential geometry offers a powerful framework for optimising and characterising finite-time thermodynamic processes, both classical and quantum. Here, we start by a pedagogical introduction to the notion of thermodynamic length. We review and connect

Deflation at Turnaround for Oscillatory Cosmology [PDF]
, 2006 It is suggested that dark energy in a brane world can help reconcile an infinitely cyclic cosmology with the second law of thermodynamics. A cyclic cosmology is described, in which dark energy with constant equation of state leads to a turnaround at ...

The History and Perspectives of Efficiency at Maximum Power of the Carnot Engine
Entropy, 2017 Finite Time Thermodynamics is generally associated with the Curzon–Ahlborn approach to the Carnot cycle. Recently, previous publications on the subject were discovered, which prove that the history of Finite Time Thermodynamics started more than sixty ...

Finite-time thermodynamics for a single-level quantum dot [PDF]
EPL (Europhysics Letters), 2010 We investigate the finite time thermodynamics of a single-level fermion system interacting with a thermal reservoir through a tunneling junction. The optimal protocol to extract the maximum work from the system when moving the single energy level between an initial higher value and a final lower value in a finite time is calculated from a quantum ...
