EROSÃO EM ÁREA RURAL NO MUNICÍPIO DE NOVA VENEZA (GO): ASPECTOS GEOMORFOLÓGICOS DA FAZENDA VARJÃO
A área de estudo está localizada na área rural do município de Nova Veneza (GO), onde a fazenda Varjão é pioneira na produção agrícola e na criação de gado. Esse estudo identificou os aspectos geomorfológicos da área em questão, tais aspectos demonstram uma suscetibilidade natural da área à processos erosivos, essa situação foi potencializada pela ação antrópica. A cobertura original foi retirada e em seu lugar implantaram pastagens e agricultura, favorecendo a ação da erosão

Digital Quantum Simulation with Rydberg Atoms
We discuss in detail the implementation of an open-system quantum simulator
with Rydberg states of neutral atoms held in an optical lattice. Our scheme
allows one to realize both coherent as well as dissipative dynamics of complex
spin models involving many-body interactions and constraints. The central
building block of the simulation scheme is constituted by a mesoscopic Rydberg
gate that permits the entanglement of several atoms in an efficient, robust and
quick protocol. In addition, optical pumping on ancillary atoms provides the
dissipative ingredient for engineering the coupling between the system and a
tailored environment. As an illustration, we discuss how the simulator enables
the simulation of coherent evolution of quantum spin models such as the
two-dimensional Heisenberg model and Kitaev's toric code, which involves
four-body spin interactions. We moreover show that in principle also the
simulation of lattice fermions can be achieved. As an example for controlled
dissipative dynamics, we discuss ground state cooling of frustration-free spin
Hamiltonians.Comment: submitted to special issue "Quantum Information with Neutral
