Semiclassical ordering in the large-N pyrochlore antiferromagnet
U. Hizi, Prashant Sharma, C. L. Henley
We study the semiclassical limit of the generalization of the pyrochlore lattice Heisenberg antiferromagnet by expanding about the saddlepoint in powers of a…
Anomalous spin transport in a two-channel-Kondo quantum dot device
Prashant Sharma
We study the response of a two-channel Kondo quantum dot device proposed by Y. Oreg and D. Goldhaber-Gordon [Phys. Rev. Lett. {\bf 90}, 136602 (2003)] to a spin-bias applied across…
The constraint of plasma power balance on runaway avoidance
Christopher J. McDevitt, Xian-Zhu Tang, Christopher J. Fontes +2
In a post-thermal-quench plasma, mitigated or unmitigated, the plasma power balance is mostly between collisional or Ohmic heating and plasma radiative cooling. In a plasma of atom…
Non-equilibrium tunneling into general quantum Hall edge states
Joel E. Moore, Prashant Sharma, Claudio Chamon
In this paper we formulate the theory of tunneling into general Abelian fractional quantum Hall edge states. In contrast to the simple Laughlin states, a number of charge transfer…
Real time error detection in metal arc welding process using Artificial Neural Netwroks
Prashant Sharma, Shaju K. Albert, S. Rajeswari
Quality assurance in production line demands reliable weld joints. Human made errors is a major cause of faulty production. Promptly Identifying errors in the weld while welding is…
Observation of fast current redistribution in an imploding plasma column
Christine Stollberg, Eyal Kroupp, Dimitry Mikitchuk +10
Spectroscopic measurements of the magnetic field evolution in a Z-pinch throughout stagnation and with particularly high spatial resolution reveal a sudden current redistribution f…
