We investigate the influence of a Markovian environment on the dynamics of interacting spinful fermionic atoms in a lattice. To explore the physical phenomena occurring at short times, we develop a method based on a slave-spin representation of fermions that is amenable to the investigation of the dynamics of dissipative systems. We apply this approach to two different dissipative couplings that can occur in current experiments: a coupling via the local density and a coupling via the local double occupancy. We complement our study based on this method, with results obtained using the adiabatic elimination technique and with an exact study of a two-site model. We uncover that the decoherence is slowed down by increasing either the interaction strength or the dissipative coupling (the Zeno effect). We also find, for the coupling to the local double occupancy, that the final steady state can sustain single-particle coherence. © 2014 American Physical Society.

While people are watching the Olympic Games, building managers will be watching their energy dashboards. Energy management software company Pulse Energy on Friday showed off an energy-monitoring system developed to make the Olympic Games in Vancouver more efficient. The software gives facilities managers a real-time readout of energy consumption at different venues. By tracking that data, building managers can make adjustments to save energy, such as turning off equipment that's not in use. The information is also available online at VenueEnergyTracker.com. The reporting system presents how much energy use and greenhouse gas emissions were avoided by the steps Olympic Game organizers have already taken, according to Pulse Energy. Building managers at the seven venues can compare how they stack up against other buildings. Pulse Energy says its software, which is used by businesses and other organizations, can save between 5 and 25 percent annually on energy bills.

There are probably more than a dozen cities that I know of competing to be known as the world's greenest or more energy-efficient or cleanest. I don't really care which one of them wins, because any focus on recalibrating community programs and development with an eye toward being kinder to the earth is a good thing in my mind. Understandably, the high-tech companies focused most on green tech -- notably Cisco and IBM -- have been rallying around these communities with the hope that their tools for better energy management, water conservation, smart transportation and such are the ones adopted by some of the highest profile projects. So, in that spirit, chalk one up for Cisco, which has cozied up to Canada's fair city of Vancouver, which has a declared goal of becoming the greenest city in the world by 2020. Cisco, along with Pulse Energy, are about to start working on several different green tech pilot projects in Vancouver, including an initiative to improve energy efficiency in commercial and government buildings, an effort to provide residents with home energy management technologies, and a plan to build out a green data center at the University of British Columbia. The parties involved are still working through who will lead what when it comes to pilot project accountability. Or, frankly, what it will cost. But you can bet this will be high-profile as things unfold.

Vancouver's Pulse Energy announced today what could be the next evolution of energy efficiency in California. Working in collaboration with Pacific Gas and Electric Company (PG&E), Pulse Energy will launch an emerging technologies pilot called Business Energy Reports. The focus of this pilot is to help the utility’s small and medium business (SMB) customers reduce energy waste by giving them new insight into their energy consumption, according to the company. The Business Energy Reports pilot will mail targeted energy insights to 15,000 SMBs this fall. The analysis is provided by Pulse Check, energy software built specifically for the needs of SMBs, grounded in behavioural research into how such organizations can optimize their operations. Every customer in the PG&E pilot will receive a report customized for their business, with customized recommendations relevant to their usage and industry, Pulse says. PG&E’s business customers will join Pulse Check users at utilities across North America and Europe.
