Quantum fluctuations in quantum lattice-systems with continuous symmetry
We discuss conditions for the absence of spontaneous breakdown of continuous symmetries in quantum lattice systems at T = 0. Our analysis is based on Pitaevskii and Stringari’s idea that the uncertainty relation can be employed to show quantum fluctuations. For the one-dimensional systems, it is shown that the ground state is invariant under the continuous transformation if a certain uniform su...
متن کاملThermal fluctuations in quantized chaotic systems
We consider a quantum system with N degrees of freedom which is classically chaotic. When N is large, and both h̄ and the quantum energy uncertainty ∆E are small, quantum chaos theory can be used to demonstrate the following results: (1) given a generic observable A, the infinite time average A of the quantum expectation value 〈A(t)〉 is independent of all aspects of the initial state other than ...
متن کاملDynamical Quantum Phase Transitions in Systems with Continuous Symmetry Breaking
Interacting many-body systems that are driven far away from equilibrium can exhibit phase transitions between dynamically emerging quantum phases, which manifest as singularities in the Loschmidt echo. Whether and under which conditions such dynamical transitions occur in higher-dimensional systems with spontaneously broken continuous symmetries is largely elusive thus far. Here, we study the d...
متن کاملFluctuations in membranes with reduced symmetry
2014 We discuss the effects of in-plane ordering of amphiphilic membranes on the statistics of their shape fluctuations. Effects of flexoand ferroelectricity as well as of several kinds of orientational order are considered. We close by a discussion of the fluctuations of a membrane immersed in an anisotropic fluid. J. Phys. France 50 (1989) 1557-1571 15 JUIN 1989, Classification Physics Abstra...
متن کاملLattice Systems with a Continuous Symmetry II . Decay of Correlations
We consider perturbations of a massless Gaussian lattice field on Z, d ̂ 3, which preserves the continuous symmetry of the Hamiltonian, e.g., It is known that for all T > 0 the correlation functions in this model do not decay exponentially. We derive a power law upper bound for all (truncated) correlation functions. Our method is based on a combination of the log concavity inequalities of Brasca...
