European Physical Journal C: Particles and Fields, 2023 In this paper, via employing the uniformly modified form of the generalized off-shell Helmholtz free energy, we investigate the topological numbers for the four-dimensional neutral Lorentzian Taub–NUT, Taub–NUT–AdS and Kerr–NUT spacetimes, and find that ...

Effect of the Minimal Length on Bose-Einstein Condensation in the Relativistic Ideal Bose Gas
, 2014 Based on the generalized uncertainty principle (GUP), the critical temperature and the Helmholtz free energy of Bose-Einstein condensation (BEC) in the relativistic ideal Bose gas are investigated. At the non-relativistic limit and the ultra-relativistic

Extended thermodynamic analysis of a charged Horndeski black hole
Physics Letters BWe perform the thermodynamic analysis of a charged Horndeski black hole (CHB) with mass m and charge q obtained from the Einstein-Horndeski-Maxwell theory. There are two solution branches: one is for the CHB and the other is for the naked singularity (NS)

Effect of electric and magnetic field on thermal property of two dimensional harmonic oscillator
Results in Physics, 2023 The energy spectrum of a 2D quantum harmonic oscillator confined by a hard wall circular cavity of size r0 in the presence of static electric and the magnetic field is computed numerically using the Bessel function basis set and the linear variational ...

Study of stability of relativistic ideal Bose-Einstein condensates
, 2012 A relativistic complex scalar boson field at finite temperature $T$ is examined below its critical Bose-Einstein condensation temperature. It is shown that at the same $T$ the state with antibosons has higher entropy, lower Helmholtz free energy and ...

Linking Phase Transitions and Quantum Entanglement at Arbitrary Temperature
, 2018 In this work, we establish a general theory of phase transitions and quantum entanglement in the equilibrium state at arbitrary temperatures. First, we derived a set of universal functional relations between the matrix elements of two-body reduced ...

Energetics of the distribution of cell wall in wood based on an eigenvalue analysis
Journal of Wood Science, 2020 Wood is a highly heterogeneous material characterized by a number of properties that vary significantly among samples. Even in woods of the same density, substantial differences in properties show up depending on the distribution pattern of their cell ...

Determination of Hydrogen’s Thermophysical Properties Using a Statistical Thermodynamic Method
Applied Sciences, 2023 Accurate determination of the thermophysical properties of hydrogen is a crucial issue in hydrogen system design. By developing computational programs, a statistical thermodynamic model based on fundamental equations of state was implemented to determine
