Centralized design and production of the ultra-high vacuum and laser-stabilization systems for the AION ultra-cold strontium laboratories
, AVS Quantum Science, Vol: 6, ISSN: 2639-0213This paper outlines the centralized design and production of the ultra-high-vacuum sidearm and laser-stabilization systems for the AION Ultra-Cold Strontium Laboratories. Commissioning data on the residual gas and steady-state pressures in the sidearm chambers, on magnetic field quality, on laser stabilization, and on the loading rate for the 3D magneto-optical trap are presented. Streamlining the design and production of the sidearm and laser stabilization systems enabled the AION Collaboration to build and equip in parallel five state-of-the-art Ultra-Cold Strontium Laboratories within 24 months by leveraging key expertise in the collaboration. This approach could serve as a model for the development and construction of other cold atom experiments, such as atomic clock experiments and neutral atom quantum computing systems, by establishing dedicated design and production units at national laboratories.

Enhanced Production of Λ_{b}^{0} Baryons in High-Multiplicity pp Collisions at sqrt[s]=13 TeV.
, Phys Rev Lett, Vol: 132The production rate of Λ_{b}^{0} baryons relative to B^{0} mesons in pp collisions at a center-of-mass energy sqrt[s]=13 TeV is measured by the LHCb experiment. The ratio of Λ_{b}^{0} to B^{0} production cross sections shows a significant dependence on both the transverse momentum and the measured charged-particle multiplicity. At low multiplicity, the ratio measured at LHCb is consistent with the value measured in e^{+}e^{-} collisions, and increases by a factor of ∼2 with increasing multiplicity. At relatively low transverse momentum, the ratio of Λ_{b}^{0} to B^{0} cross sections is higher than what is measured in e^{+}e^{-} collisions, but converges with the e^{+}e^{-} ratio as the momentum increases. These results imply that the evolution of heavy b quarks into final-state hadrons is influenced by the density of the hadronic environment produced in the collision. Comparisons with several models and implications for the mechanisms enforcing quark confinement are discussed.

Exploring the exchange bias of Gd and MnPt: A combined structural and magnetic investigation
, Thin Solid Films, Vol: 790, ISSN: 0040-6090Magnetic manipulation in thin films is essential for modern technology. Extensive studies on exchange bias with antiferromagnetic materials and transition metals exist, but research on rare earth elements is limited. This study investigates the formation of the L10-MnPt phase and a ferromagnetic-like Gd phase on Si/SiO2 thin films. We observed thickness-dependent anisotropic magnetic fields in Gd thin films and thickness-dependent exchange bias in the heterojunctions. These findings enhance our understanding of the magnetic properties of MnPt, Gd and the multilayer heterostructure.

Magnetic, magnetocaloric and critical behavior studies in Heusler compounds Co<inf>2-x</inf>Cr<inf>1+x</inf>Al
, Journal of Magnetism and Magnetic Materials, Vol: 591, ISSN: 0304-8853The polycrystalline Co2-xCr1+xAl (x = 0, 0.2, 0.4, 0.6, 0.8) compounds have been prepared successfully using the arc-melting technique. Room temperature XRD patterns indicate that all compounds have Heusler compound-like fcc structure along with B2 disorder. With the increasing Cr concentration within the compounds, the value of the lattice parameter increases. All compounds undergo a second-order paramagnetic (PM) to ferromagnetic (FM) transition and the value of PM-FM transition temperature (TC) decreases from 328 K to 134 K with increasing Cr concentration. For all compounds, the experimentally obtained value of MS is quite lower than the value of MS calculated from the well-known Slater-Pauling rule and the values of MS also decrease with increasing Cr concentration within the compounds. The magnetic entropy changes (ΔSM) and relative cooling power (RCP) for the Co2-xCr1+xAl (x = 0, 0.2, 0.4, 0.6) compounds have been calculated. The maximum magnetic entropy change (-ΔSMmax) and RCP both decrease with increasing the Cr concentration within the compounds. The values of critical exponents β, γ, δ associated with the magnetic phase transition have been estimated using the various well-established methods such as modified Arrott plot, power-law, Kouvel-Fisher methods and critical isotherm analysis for the Co2-xCr1+xAl (x = 0, 0.2, 0.4, 0.6) compounds. The obtained values of critical exponents, β and γ, for all compounds, do not follow any conventional universality class. Except for Co2CrAl (x = 0), the obtained β values for the other compounds (Cr-doped compounds) are quite higher than the highest β value among all theoretical models (the highest β value is 0.5 which belongs to the mean-field model). The high value of β occurs due to the Cr doping on the Co site in the system which creates disorder in the system. β>0.5 for all compounds, which indicates the long-range ordering below TC.

Exploring complex magnetic phase transitions and magnetocaloric effect in the nanocrystalline Nd<inf>0.5</inf>Ca<inf>0.5</inf>MnO<inf>3</inf> compound
, Ceramics International, Vol: 50, Pages: 5594-5603, ISSN: 0272-8842In this article, we have investigated the temperature and magnetic field-induced complex magnetic phases and magnetocaloric properties of the nanocrystalline Nd0.5Ca0.5MnO3 (NCMO) compound in detail. The compound exhibits charge-ordered antiferromagnetic (CO-AFM) and charge-orbital-ordered antiferromagnetic (AFM) phases at TCO≃ 225 K and TN= 160 K respectively. At the intermediate temperature range, i.e. TN≤ T ≤ TCO, an unfamiliar magnetic state is present where the orbital ordering of manganese ions sets progressively. Both the short-range and zig-zag ordered ferromagnetic (FM) chains and an AFM phase coexist within this temperature window. The effect of magnetic field and temperature drastically modifies the fragile magnetic ground state and this change is also reflected in the magnetocaloric properties of the studied compound. At the low-temperature region, an inverse magnetocaloric effect (MCE) is noticed due to the kinetically arrested magnetic moments of the AFM phase. However, a conventional MCE is noticed in the high-temperature regime. The anomalous behavior of the MCE in the nanocrystalline NCMO compound is analyzed by considering the effect of the reduction of particle size and the meta-stable nature of the magnetic ground state. In addition, we have paid attention to the hysteretic losses associated with the first-order phase transition (FOPT) in order to estimate the magnetic cooling capacity for the material. These studies carry notable importance for the usefulness of nanocrystalline half-doped manganite compounds not only for basic scientific research purpose, but also having possible practical utilization in the magnetic refrigeration industries.
