A numerical method, based on the discrete lattice Boltzmann equation, is presented for solving the volume-averaged Navier-Stokes equations. With a mo…

Efficiency at maximum power (MP) output for an engine with a passive piston without mechanical controls between two reservoirs is theoretically studi…

We present a simple model for the development of shear layers between parallel flows in confining channels. Such flows are important across a wide ra…

The recent analysis of low-redshift supernovae (SN) has increased the apparent tension between the value of $H_0$ estimated from low and high redshif…

The standard resonance conditions for Bragg scattering as well as weakly nonlinear wave triads have been traditionally derived in the absence of any …

We study the existence and stability criteria for circular geodesics of spherically symmetric tidal charged black hole~(BH). We investigate in detail…

We proposed a non-hermitian PT-symmetric model for describing the light field of two cavities interacting through a 2D-chiral mirror. Analysing the time evolution of the system, we showed that the probability amplitude for the exchange of a photon f…

Inspired by a recently observed asymmetry in the transmission of circularly polarized light through a metamaterial, we present a non-hermitian PT-sym…

Relativistic thick ring models are constructed using previously found analytical Newtonian potential-density pairs for flat rings and toroidal struct…

Numerical simulations of the shallow water equations on rotating spheres produce mixtures of robust vortices and alternating zonal jets, as seen in t…

We propose the notion of $E_{2}$-quasi-exact solvability and apply this idea to find explicit solutions to the eigenvalue problem for a non-Hermitian…

An analytical solution for the flow field of a shear flow over a rectangular cavity containing a second immiscible fluid is derived. While flow of a …

Analytical expressions for the flow field as well as for the effective slip length of a shear flow over a surface with periodic rectangular grooves a…

The concept of leader--follower (or Stackelberg) equilibrium plays a central role in a number of real--world applications of game theory. While the c…

One of the principal mechanisms by which surfaces and interfaces affect microbial life is by perturbing the hydrodynamic flows generated by swimming.…

We study for the first time how a new class of stars could impact an ensemble of pulsars with known masses and spin-periods. These new compact object…

Radio pulsar polarization exhibits a number of complex phenomena that are classified into the realm of `beyond the rotating vector model' (RVM). It i…

The anomalous magnetic moment of the muon currently exhibits a discrepancy of about three standard deviations between the experimental value and rece…

The WHOT-QCD Collaboration is pushing forward a series of lattice studies of QCD at finite temperatures and densities using improved Wilson quarks. B…

The appearance of eruptive space plasma processes, e.g., in eruptive flares as observed in the solar atmosphere, is usually assumed to be caused by m…

We present results for the ground-state mass shifts of octet baryons due to the presence of a medium of pions or kaons from a lattice QCD calculation…
