Dissipative Phase Transitions
نویسنده
چکیده
The transport properties of a quantum mechanical system coupled to an environment deviate sharply from those of the isolated system when the coupling exceeds a critical value. This effect is governed by a quantum phase transition, which takes place because the environment suppresses quantum fluctuations. This paper explains why dissipation leads to spontaneous symmetry breaking at T = 0, and how dissipative couplings stabilize superconductivity in Josephson junction arrays and nanowires.

Tunable quantum phase transitions in a resonant level coupled to two dissipative baths
We study tunneling through a resonant level connected to two dissipative bosonic baths: one is the resistive environment of the source and drain leads, while the second comes from coupling to potential fluctuations on a resistive gate. We show that several quantum phase transitions (QPT) occur in such a model, transitions which emulate those found in interacting systems such as Luttinger liquid...
متن کاملDissipation and spontaneous symmetry breaking in brain dynamics
We compare the predictions of the dissipative quantum model of brain with neurophysiological data collected from electroencephalograms resulting from high-density arrays fixed on the surfaces of primary sensory and limbic areas of trained rabbits and cats. Functional brain imaging in relation to behavior reveals the formation of coherent domains of synchronized neuronal oscillatory activity and...

متن کاملCortical aperiodic ‘ clock ’ enabling phase transitions at theta rates
Brains are open thermodynamic systems, continually dissipating metabolic energy as heat in constructing spatiotemporal patterns of neural activity. Here observations on patterns of cortical oscillations are described as Prigogine’s “dissipative structures” forming at conditionally stable operating points far from equilibrium. The approach is to locate experimentally a small-signal, near-linear ...
متن کاملUnconventional magnetism via optical pumping of interacting spin systems.
We consider strongly interacting systems of effective spins, subject to dissipative spin-flip processes associated with optical pumping. We predict the existence of novel magnetic phases in the steady state of this system, which emerge due to the competition between coherent and dissipative processes. Specifically, for strongly anisotropic spin-spin interactions, we find ferromagnetic, antiferr...
