The effect of Cu on phase stability and magnetic properties of τ-MnAl: A comparative study of Mn55-xAl45Cux and Mn55Al45-xCux (x = 0.0, 2.0, 2.5) alloys Open
The hard ferromagnetic τ-phase in Mn-Al material system continues to attract attention since it has potential to be developed as permanent magnet without the use of critical/expensive elements. However, this phase is metastable, requiring …

Energy dependence of intermittency for charged hadrons in Au+Au collisions at RHIC Open
Density fluctuations near the QCD critical point can be probed via an intermittency analysis in relativistic heavy-ion collisions. We report the first measurement of intermittency in Au+Au collisions at $\\sqrt{s{NN}}$ = 7.7-200 GeV measur…

Search for the chiral magnetic wave using anisotropic flow of identified particles at energies available at the BNL Relativistic Heavy Ion Collider Open
The chiral magnetic wave (CMW) has been theorized to propagate in the deconfined nuclear medium formed in high-energy heavy-ion collisions, and to cause a difference in elliptic flow (v2) between negatively and positively charged hadrons. …

Measurement of away-side broadening with self-subtraction of flow in Au+Au collisions at GeV * Open
High transverse momentum ( ) particle production is suppressed owing to the parton (jet) energy loss in the hot dense medium created in relativistic heavy-ion collisions. Redistribution of energy at low-to-modest has been difficult to meas…
