This paper is devoted to studying the impact of thermal fluctuations on thermodynamics of rotating as well as charged anti-de Sitter black holes with the Newman–Unti–Tamburino(NUT)parameter.To this end,we derive the analytic expression of thermodynamic variables,namely the Hawking temperature,volume,angular velocity,and entropy within the limits of extended phase space.These variables meet the first law of thermodynamics as well as the Smarr relation in the presence of new NUT charge.To analyze the effects of quantum fluctuations,we derive the exact expression of corrected entropy,which yields modification in other thermodynamical equations of state.The local stability and phase transition of the considered black hole are also examined through specific heat.It is found that the NUT parameter increases the stability of small black holes,while the logarithmic corrections induce instability in the system.

Chinese Physics B 2011年第2期20卷 104-109页

作者： Wang Xiu-Mei He Ji-Zhou Liang Hong-Ni Department of Physics Nanchang University Nanchang 330031 China CALLS Information Service Center of Jiangxi Province Nanchang University Nanchang 330031 China

This paper establishes a model of a nonlinear diode refrigerator consisting of two diodes switched in the opposite directions and located in two heat reservoirs with different temperatures. Based on the theory of thermal fluctuations, the expressions of the heat flux absorbed from the heat reservoirs are derived. After the heat leak between the two reservoirs is considered, the cooling rate and the coefficient of performance are obtained analytically. The influence of the heat leak and the temperature ratio on the performance characteristics of the refrigerator is analysed in detail.

A Hybrid Immersed Boundary/Coarse-Graining Method for Modeling Inextensible Semi-Flexible Filaments in thermally Fluctuating Fluids Dedicated to Professor Karl Stark Pister for his 95th birthday

Computer Modeling in Engineering & Sciences 2021年第12期129卷 1243-1258页

作者： Magdalini Ntetsika Panayiotis Papadopoulos Department of Mechanical Engineering University of CaliforniaBerkeleyCA94720-1740USA

A new and computationally efficient version of the immersed boundary method,which is combined with the coarse-graining method,is introduced for modeling inextensible filaments immersed in low-Reynolds number flows.This is used to represent actin biopolymers,which are constituent elements of the cytoskeleton,a complex network-like structure that plays a fundamental role in shape morphology.An extension of the traditional immersed boundary method to include a stochastic stress tensor is also proposed in order to model the thermal fluctuations in the fluid at smaller scales.By way of validation,the response of a single,massless,inextensible semiflexible filament immersed in a thermally fluctuating fluid is obtained using the suggested numerical scheme and the resulting time-averaged contraction of the filament is compared to the theoretical value obtained from the worm-like chain model.
