Helical dynamo growth at modest versus extreme magnetic Reynolds numbers
Hongzhe Zhou, Eric Blackman
Understanding large-scale magnetic field growth in astrophysical objects is a persistent challenge. We tackle the long-standing question of how much helical large-scale dynamo grow…
Exploring the electromagnetic properties of the and molecular states
Fu-Lai Wang, Si-Qiang Luo, Hong-Yan Zhou +2
This paper presents a systematic investigation of the electromagnetic properties of the hidden-charm molecular pentaquarks within the constituent quark model. Specifically, it focu…
Probing the electromagnetic properties of the -type doubly charmed molecular pentaquarks
Hong-Yan Zhou, Fu-Lai Wang, Zhan-Wei Liu +1
In this work, we discuss the electromagnetic properties of the -wave -type doubly charmed molecular pentaquarks, which have close relation to their inner struc…
Batchelor, Saffman, and Kazantsev spectra in galactic small-scale dynamos
Axel Brandenburg, Hongzhe Zhou, Ramkishor Sharma
The magnetic fields in galaxy clusters and probably also in the interstellar medium are believed to be generated by a small-scale dynamo. Theoretically, during its kinematic stage,…
Scaling of the Hosking integral in decaying magnetically-dominated turbulence
Hongzhe Zhou, Ramkishor Sharma, Axel Brandenburg
The Saffman helicity invariant of Hosking and Schekochihin (2021, PRX 11, 041005), which we here call the Hosking integral, has emerged as an important quantity that may govern the…
On the shear-current effect: toward understanding why theories and simulations have mutually and separately conflicted
Hongzhe Zhou, Eric G. Blackman
The shear-current effect (SCE) of mean-field dynamo theory refers to the combination of a shear flow and a turbulent coefficient with a favorable negative sign for exponen…
Influence of inhomogeneous stochasticity on the falsifiability of mean-field theories and examples from accretion disc modeling
Hongzhe Zhou, Eric G. Blackman
Despite spatial and temporal fluctuations in turbulent astrophysical systems, mean-field theories can be used to describe their secular evolution. However, observations taken over…
Generalized quenching of large-scale magnetic dynamos in anisotropic flows
Hongzhe Zhou, Eric G. Blackman
The buildup of small-scale magnetic helicity which accompanies the oppositely signed growth on large scales is central to conventional dynamical quenching theories of mean-field dy…
Calculating turbulent transport tensors by averaging single plume dynamics and application to dynamos
Hongzhe Zhou, Eric G. Blackman
Transport coefficients in turbulence are comprised of correlation functions between turbulent fluctuations and efficient methods to calculate them are desirable. For example, in me…
Derivation and precision of mean field electrodynamics with mesoscale fluctuations
Hongzhe Zhou, Eric G. Blackman, Luke Chamandy
Mean field electrodynamics (MFE) facilitates practical modeling of secular, large scale properties of astrophysical or laboratory systems with fluctuations.Practitioners commonly a…
Some consequences of shear on galactic dynamos with helicity fluxes
Hongzhe Zhou, Eric G. Blackman
Galactic dynamo models sustained by supernova (SN) driven turbulence and differential rotation have revealed that the sustenance of large scale fields requires a flux of small scal…
