Cavity assisted measurements of heat and work in optical lattices
... Although the two-point measurement is the most common definition of work in the quan- tum community, having the advantage of fulfill- ing the first law and the Jarzynski equality [21], it is not the only one. In fact it ...

Pfaffian like ground states for bosonic atoms and molecules in one dimensional optical lattices
... such 1D non-Abelian states must be braided in order to compute. This could be achieved by combining 1D systems into a 2D network as previously proposed in the case of Majorana fermions [42]. Understanding how to build ...

Particle statistics and lossy dynamics of ultracold atoms in optical lattices
... In the past few years, there has been rapid progress in the characterization and control of dissipative dynam- ics for ultracold atoms in optical lattices. While these systems are most known for the ...

Interactions and collisions of discrete breathers in two-species Bose-Einstein condensates in optical lattices
... So far most of the work has concentrated on the existence of two-species solitons and their stability [24–32]. Without a lattice potential, two-component (symbiotic) solitons were found with attractive interspecies ...

Dynamical disentangling and cooling of atoms in bilayer optical lattices
... The first milestone in this direction would be the sim- plified preparation of quantum magnetic ordering driven by super-exchange processes, which is challenging due to the small energy gaps involved [15–17]. Seminal ...

Stationary and traveling solitons via local dissipations in Bose-Einstein condensates in ring optical lattices
... For completeness we show that localized structures can also be obtained via localized dissipations by starting from a homogeneous distribution of atoms across the optical lat- tice with random phases in analogy ...

Nonequilibrium dynamics of bosonic atoms in optical lattices : decoherence of many-body states due to spontaneous emission
... We compute the time dependence of characteristic correla- tion functions based on both perturbation theory calculations and a time-dependent calculation of the dissipative many-body dynamics. The time-dependent dynamics ...

Dynamical crystal creation with polar molecules or Rydberg atoms in optical lattices
... Abstract. We investigate the dynamical formation of crystalline states with systems of polar molecules or Rydberg atoms loaded into a deep optical lattice. External fields in these systems can be used to couple ...

Adiabatic Preparation of Many-Body States in Optical Lattices
... The final Hamiltonian (1) for the AF states has a con- tinuum of (ungapped) excitations, which will always re- sult in some excitations for a finite preparation time. We analyze this imperfection in a three dimensional ...
