Shortcuts to Adiabaticity
Quantum adiabatic processes--that keep constant the populations in the instantaneous eigenbasis of a time-dependent Hamiltonian--are very useful to prepare and manipulate states, but take typically a…
Classical and Quantum Shortcuts to Adiabaticity for Scale-Invariant Driving
A natural nonequilibrium process that takes a system from one equilibrium state to another in a short time always involves dissipation. But, it's actually possible in quantum control to design and…
Shortcuts to adiabaticity by counterdiabatic driving.
The evolution of a system induced by counterdiabatic driving mimics the adiabatic dynamics without the requirement of slow driving. Engineering it involves diagonalizing the instantaneous Hamiltonian…
Universality of Phase Transition Dynamics: Topological Defects from Symmetry Breaking
In the course of a nonequilibrium continuous phase transition, the dynamics ceases to be adiabatic in the vicinity of the critical point as a result of the critical slowing down (the divergence of…
Time in Quantum Mechanics - Vol. 2
TLDR
Thorough and lucid, this book is written as an introductory guide for newcomers to the subject and is also useful as a reference for the expert.
Scrambling the spectral form factor: Unitarity constraints and exact results
Quantum speed limits set an upper bound to the rate at which a quantum system can evolve, and as such can be used to analyze the scrambling of information. To this end, we consider the survival…
Shortcuts to adiabaticity in a time-dependent box
A method is proposed to drive an ultrafast non-adiabatic dynamics of an ultracold gas trapped in a time-dependent box potential. The resulting state is free from spurious excitations associated with…
Universal Statistics of Topological Defects Formed in a Quantum Phase Transition.
When a quantum phase transition is crossed in finite time, critical slowing down leads to the breakdown of adiabatic dynamics and the formation of topological defects. The average density of defects…
Synthesis and structural characterization of ZnxFe3−xO4 ferrite nanoparticles obtained by an electrochemical method
A series of zinc ferrite nanoparticles were synthesized following a single-step electrochemical method in aqueous medium. This strategy allowed the control of both the size and chemical composition…
2D particles forming a nanostructured shell: A step forward cool NIR reflectivity for CoAl2O4 pigments
Abstract Blue CoAl 2 O 4 are inorganic pigments with impressive optical effects and a high chemical stability. However, this spinel type structure has two main drawbacks: cobalt is scarce and…
