Vibrational degrees of freedom in trapped-ion systems have recently been gaining attention as a quantum resource, beyond the role mediator for entangling operations on internal freedom, because large available Hilbert space. The vibrational modes can be represented harmonic oscillators and thus offer space with infinite dimension. Here we review recent theoretical experimental progress coherent...

copper smelting slags are hard materials. therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. copper smelting slags in the bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm. with this gri...

Abstract Motivated by a high demand, the research interest in personalized artificial tissues is steadily increasing. Combining knowledge of additive manufacturing and tissue engineering, field 3D bioprinting emerged. This work presents six-degree-of-freedom mechanically actuated extrusion bioprinter within sterile working environment. The system based on an off-the-shelf robot arm custom modul...

Electronic-vibrational dynamics in molecular systems that interact with an environment involve a large number of degrees of freedom and are therefore often described by means of open quantum system approaches. A popular approach is to include only the electronic degrees of freedom into the system part and to couple these to a non-Markovian bath of harmonic vibrational modes that is characterize...

We prepare metastable glassy states in a model glass former made of Lennard-Jones particles by sampling biased ensembles of trajectories with low dynamical activity. These trajectories form an inactive dynamical phase whose "fast" vibrational degrees of freedom are maintained at thermal equilibrium by contact with a heat bath, while the "slow" structural degrees of freedom are located in deep v...
