Abstract We prove the quantum Zeno effect in open systems whose evolution, governed by dynamical semigroups, is repeatedly and frequently interrupted action of a operation. For case semigroup with bounded generator, our analysis leads to refinement existing results extends them larger class operations. also existence novel strong limit for operations which certain spectral gap assumption, all p...

Many quantitative approaches to the dynamical scrambling of information in quantum systems involve study out-of-time-ordered correlators (OTOCs). In this paper, we introduce an algebraic OTOC ($\mathcal{A}$-OTOC) that allows us generalized subsystems under channels. For closed systems, framework was recently employed unify information-theoretic notions operator entanglement, coherence-generatin...

Abstract We generalize time-evolving matrix product operators method to nonequilibrium quantum transport problems. The current is obtained via numerical differentiation of the generating functional which represented as a tensor network. approach numerically exact and non-Markovian effects are fully taken into account. In process, part heat that flows out from bath system other baths, rest store...

Controlling the temperature of nanoscale quantum systems is becoming increasingly important in efforts to develop thermal devices such as heat valves, engines, and refrigerators explore fundamental concepts thermodynamics. In practice, however, it challenging generate arbitrary time-dependent temperatures, similarly what has been achieved for electronic voltage pulses. To overcome this problem,...

Abstract. Discrete Global Grid Systems (DGGS) are spatial reference systems that use a hierarchical tessellation of cells to partition and address the globe provide alternative data format indexing methods as compared traditional vector raster data. In order effectively DGGS, functional software needs be available indexed into DGGS. We compare APIs 5 main open-source DGGS implementations – Uber...
