Sharp bounds for higher Steklov-Dirichlet eigenvalues on domains with spherical holes
Sagar Basak, Anisa Chorwadwala, Sheela Verma
We consider mixed Steklov-Dirichlet eigenvalue problem on smooth bounded domains in Riemannian manifolds. Under certain symmetry assumptions on multiconnected domains in $\mathbb{R…
Evidence for Conical Magnetic Structure in M-type BaFe12O19 Hexaferrite: A Combined Single-Crystal XMCD and Neutron Diffraction Study
Keshav Kumar, Shrawan K. Mishra, Sanjay Singh +5
The magnetic ground state of BaFe12O19 (BFO) was investigated using X-ray absorption at 1.2 K and 1.5 K, respectively. The XMCD measurements on single-crystals of BFO in grazing in…
Evidence for coexistence of spin-glass and ferrimagnetic phases in BaFe12O19 due to basal plane freezing
Keshav Kumar, Shrawan Kumar Mishra, Ivan Baev +2
We present here the results of low-temperature magnetization and X-ray magnetic circular dichroism studies on single crystals of BaFe12O19 which reveal for the first time the emerg…
Non-trivial saddles in microscopic description of black holes
Pranav Kumar, Swapnamay Mondal
Non-trivial gravitational saddles have played a key role in the island proposal for the black hole information paradox. It is worth asking if non-trivial saddles exist in microscop…
Identified charged-hadron production in Al, HeAu, and CuAu collisions at GeV and in UU collisions at GeV
PHENIX Collaboration, N. J. Abdulameer, U. Acharya +477
The PHENIX experiment has performed a systematic study of identified charged-hadron (, , , ) production at midrapidity in Al, HeAu, CuAu c…
Expanding neutrino oscillation parameter measurements in NOvA using a Bayesian approach
NOvA Collaboration, M. A. Acero, B. Acharya +196
NOvA is a long-baseline neutrino oscillation experiment that measures oscillations in charged-current (disappearance) and (appearance)…
