A three-level system attached to three thermal baths is manipulated be a microscopic device integrating valve, refrigerator, an amplifier, and thermometer in the quantum regime, via tuning inner coupling strength of temperatures external baths. We discuss role as well steady-state coherence these functions using Redfield master equation under partial secular approximation. high-sensitive for lo...

OBJECTIVE Balneotherapy (or spa therapy, mineral baths) for patients with arthritis is one of the oldest forms of therapy. We assessed effectiveness of balneotherapy for patients with osteoarthritis (OA). METHODS We performed a broad search strategy to retrieve eligible studies, selecting randomized controlled trials comparing balneotherapy with any intervention or with no intervention. Two a...

Quantum simulation involves engineering devices to implement different Hamiltonians and measuring their quantized spectra study quantum many-body systems. Recent developments in topological photonics have shown the possibility of studying novel phenomena by controlling properties such devices. Here, using coupled arrays up 16 high Q silicon nanocavities, we experimentally realize photonic baths...

Practical implementations of quantum technology are limited by unavoidable effects of decoherence and dissipation. With achieved experimental control for individual atoms and photons, more complex platforms composed by several units can be assembled enabling distinctive forms of dissipation and decoherence, in independent heat baths or collectively into a common bath, with dramatic consequences...

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...
