Tomographically reconstructed master equations for any open quantum dynamics [PDF]

Quantum, 2017
Memory effects in open quantum dynamics are often incorporated in the equation of motion through a superoperator known as the memory kernel, which encodes how past states affect future dynamics.

Quantum jumps are more quantum than quantum diffusion

New Journal of Physics, 2014
It was recently argued (Wiseman and Gambetta 2012 Phys. Rev. Lett. http://dx.doi.org/10.1103/PhysRevLett.108.220402 108 http://dx.doi.org/10.1103/PhysRevLett.108.220402 ) that the stochastic dynamics (jumps or diffusion) of an open quantum system are not

Glassy quantum dynamics in translation invariant fracton models [PDF]

, 2017
We investigate relaxation in the recently discovered ``fracton'' models and discover that these models naturally host glassy quantum dynamics in the absence of quenched disorder. We begin with a discussion of ``type I'' fracton models, in the taxonomy of

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

Advanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Integrable crosscap states in gl $$ \mathfrak{gl} $$ (N) spin chains

Journal of High Energy Physics, 2022
We study the integrable crosscap states of the integrable quantum spin chains and we classify them for the gl $$ \mathfrak{gl} $$ (N) symmetric models. We also give a derivation for the exact overlaps between the integrable crosscap states and the Bethe ...
