“…In table I we list the saturation properties like the saturation density (ρ 0 ), binding energy per particle (e 0 ), nuclear incompressibility (K 0 ), symmetry energy coefficient (J 0 ) and the slope parameter (L 0 ) of the chosen hadronic model. The symmetry energy coefficient (J 0 ) and the slope parameter (L 0 ) of the chosen hadronic model are quite consistent with the recent findings of [55] obtained from the correlation between them and the neutron skin thickness of 208 Pb (R 208 skin ) as measured by the PREX-II experiment. The binding energy per particle (e 0 ) and the saturation density (ρ 0 ) also satisfy the experimental constraints [68].…”

We compute the hybrid star (HS) properties with the help of Maxwell construction. For the purpose we choose a fixed hadronic model and four different forms of MIT bag model for the quark phase. We investigate thoroughly the effects of the different parameters of the bag model on the speed of sound in HS matter and the structural properties of HSs in the light of the various recent constraints on them from astrophysical observations. We also examine the importance of each parameter involved in these four forms of bag model in the context appearance of special points (SPs) in the mass-radius (M − R) variation of HSs. We find that among all these parameters the bag pressure play the most significant role in the emergence of the SPs in the M − R dependence of HSs.

“…where the sum is over ω = 2π n/T for integer n, and the overline represents complex conjugation (149,196,219,324). When the material is passive, the work must be nonpositive for all possible cycles, which implies that M ijkℓ (ω) (viewed as a linear operator on rank two tensors, for instance, using the matrix representation of Sections 2.1.1 and 3.2.1) must be positive semidefinite for all frequencies ω (325-327).…”

Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is not the case. These materials display additional linear response coefficients known as odd viscosity and odd elasticity. We first introduce odd viscosity and odd elasticity from a continuum perspective, with an emphasis on their rich phenomenology, including transverse responses, modified dislocation dynamics, and topological waves. We then provide an overview of systems that display odd viscosity and odd elasticity. These systems range from quantum fluids and astrophysical gases to active and driven matter. Finally, we comment on microscopic mechanisms by which odd viscosity and odd elasticity arise.

“…In our recent paper, we used the variational principle of the Onsager-Machlup integral to describe the stochastic dynamics of a micromachine with odd elasticity [15]. Furthermore, the concept of odd viscoelasticity [16] and odd diffusion tensor have also been reported [17].…”

We investigate the statistical properties of fluctuations in active systems that are governed by non-symmetric responses. Both an underdamped Langevin system with an odd resistance tensor and an overdamped Langevin system with an odd elastic tensor are studied. For a system in thermal equilibrium, the time-correlation functions should satisfy time-reversal symmetry and the anti-symmetric parts of the correlation functions should vanish. For the odd Langevin systems, however, we find that the anti-symmetric parts of the time-correlation functions can exist and that they are proportional to either the odd resistance coefficient or the odd elastic constant. This means that the time-reversal invariance of the correlation functions is broken due to the presence of odd responses in active systems. Using the short-time asymptotic expressions of the time-correlation functions, one can estimate an odd elastic constant of an active material such as an enzyme or a motor protein.
