Residual Stress in Additive Manufactured Nickel Alloy 625 Parts

Author(s)
Lindsey B. Bass, Justin L Milner, Thomas Gnaupel-Herold, Shawn P. Moylan
One of the key barriers to widespread adoption of additive manufacturing (AM) for metal parts is the build-up of residual stresses. In the laser-based powder...

Perpetual emulation threshold of PT-symmetric Hamiltonians

Author(s)
Ian B. Spielman, Clive Emary, Dimitris Trypogeorgos, Ana Vald?s-Curiel
We describe a technique to emulate a two-level PT-symmetric spin Hamiltonian, replete with gain and loss, using only the unitary dynamics of a larger quantum...
