Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

Quantum simulators are controllable quantum systems that can be used to simulate other
quantum systems. Being able to tackle problems that are intractable on classical computers …

Traversal of a symmetry-breaking phase transition at finite rates can lead to causally
separated regions with incompatible symmetries and the formation of defects at their …

The control of internal and motional quantum degrees of freedom of laser-cooled trapped
ions has been subject to intense theoretical and experimental research for about three …

We address on general quantum-statistical grounds the problem of optimal detection of the
Unruh-Hawking effect. We show that the effect signatures are magnified up to potentially …

The nonequilibrium dynamics of an ion chain in a highly anisotropic trap is studied when the
transverse trap frequency is quenched across the value at which the chain undergoes a …

Measuring heat flow through nanoscale devices poses formidable practical difficulties as
there is no “ampere meter” for heat. We propose to overcome this problem in a chain of …

We consider the number distribution of topological defects resulting from the finite-time
crossing of a continuous phase transition and identify signatures of universality beyond the …

A string of trapped ions at zero temperature exhibits a structural phase transition to a zigzag
structure, tuned by reducing the transverse trap potential or the interparticle distance. The …

Ion Coulomb crystals, formed by atomic ions at low temperatures in radiofrequency and
Penning ion traps, are structures that have remarkable properties and many applications …
