: Gas discharge plasmas are low-temperature nonequilibrium plasmas that have a wide range of scientific and technological applications. The particle-in-cell/Monte Carlo collision (PIC/MCC) method is a reliable approach for numerical analyses and simulations of such plasmas. In this study, we first provide a detailed description of the basics of this method. We then verify the programme code that we developed in Fortran by benchmarking the code against a widely referred reference study simulating a radiofrequency capacitively coupled plasma (RFCCP) in helium for various discharge conditions. We show that the results of the present study are in good agreement with that of the reference benchmark study. We also demonstrate that although PIC/MCC is a computationally demanding method, it is still possible to conduct some one-dimensional plasma simulations with standard personal computers within hours, thanks to recent advancements in computing technologies. More rigorous and especially high-dimensional problems, however, require acceleration and parallelization strategies.

The field of quantum resource theory (QRT) has emerged as an invaluable framework for the examination of small and strongly correlated quantum systems, surpassing the boundaries imposed by traditional statistical treatments. The fundamental objective of general QRTs is to characterize these systems by precisely quantifying the level of control attainable to an experimenter. In this review article, we refrain from providing an exhaustive summary of the extensive literature on QRT. Rather, our focus centers on a specific sub-literature founded upon the theory of majorization. The primary aim is to augment our comprehension of genuine quantum phenomena manifested across diverse technological applications and incite investigations into novel resource theories encompassing multiple types of resources. Consequently, we emphasize the underlying similarities shared by various resources, including bipartite quantum entanglement, quantum coherence, and superposition, alongside informational, thermal, and generalized nonequilibrium resources.

: In this paper, we generalize the shortcuts to adiabacity for the quantum Rabi model by simultaneously modulating its two components, namely, the two-level system and the cavity mode. This will eliminate the counterrotating terms which in turn helps to simulate the Rabi model by the Jaynes-Cummings model without requiring a largely detuned light-matter coupling. We focus on the low-frequency modulations since it is easy to realize them experimentally. The results show that these modulations can significantly shorten the evaluation time, generate much larger entanglement cat states, and robust against imperfection of time evaluation and dissipation.

The requirement to boost the resolution of nanopore-based biosequencing devices necessitates the integration of novel biosensing techniques with reduced sensitivity to background noise. In this article, we probe the signatures of translocating polymers in magnetic fields induced by ionic currents through membrane nanopores. Within the framework of a previously introduced charge transport theory, we evaluate the magnetic field signals generated by voltage- and pressure-driven DNA translocation events in monovalent salt solutions. Our formalism reveals that in voltage-driven transport, the translocating polymer suppresses the induced magnetic field via the steric blockage of the ion current through the mid-pore. In the case of pressure-driven transport, the magnetic field reduction by translocation originates from the negative electrokinetic contribution of the anionic DNA surface charges to the streaming current predominantly composed of salt cations. The magnitude of the corresponding field signals is located in the nano-Tesla range covered by the resolution of the magnetoelectric sensors able to detect magnetic fields down to the pico-Tesla range. This suggests that the integration of magnetic field detection techniques into the current biosequencing approaches can complement efficiently the conventional biosensing strategies employing ionic current readouts with high susceptibility to background noise.

: The exotic neutral current introduces new interactions beyond standard model (BSM) which consist of all possible four-fermion nonderivative Lorentz structures: scalar (S), pseudoscalar (P), vector (V), axial-vector (A), and tensor (T). In this work, we investigate the prediction of this model via the coherent elastic neutrino-nucleus scattering (CE ν NS). The differential cross section spectrum of CE ν NS for three nuclei in regards to experiment advancement are calculated in the framework of this model independent proposal using recent obtained bound. We present the ratio of this exotic model with the SM for various threshold energies. Significant bound is shown lie in the lower threshold case. The contributions from exotic neutral current interactions can considerably increase the rate of production relative to the SM case.

It has been established that the Coulomb interactions can transform the electron gas into a viscous fluid. This fluid is realized in a number of platforms, including graphene and two-dimensional semiconductor heterostructures. The defining characteristic of the electron fluid is the formation of layers of charge carriers that are in local thermodynamic equilibrium, as in classical fluids. In the presence of nonuniformities, whirlpools and nontrivial flow profiles are formed, which have been directly imaged in recent experiments. In this paper, we theoretically study the response of the electron fluid to localized magnetic fields. We find that the electric current is suppressed by viscous vortices in regions where magnetic field is sharply varying, causing strong transport signatures. Experimentally, our considerations are relevant since local magnetic fields can be applied to the system through implanting adatoms or embedding micromagnets in the top-gate. Our theory is essential for the characterization and future applications of electron fluids in hydrodynamic spin transport.
