Quantum first order phase transitions
The scaling theory of critical phenomena has been successfully extended for classical first order transitions even though the correlation length does not diverge in these transitions. In this paper we apply the scaling ideas to quantum first order transitions. The usefulness of this approach is illustrated treating the problems of a superconductor coupled to a gauge field and of a biquadratic H...
متن کاملQuantum phase transitions in spin systems and the high temperature limit of continuum quantum field theories
We study the finite temperature crossovers in the vicinity of a zero temperature quantum phase transition. The universal crossover functions are observables of a continuum quantum field theory. Particular attention is focussed on the high temperature limit of the continuum field theory, the socalled “quantum-critical” region. Basic features of crossovers are illustrated by a simple solvable mod...
متن کاملLocal Operators in Massive Quantum Field Theories
A fundamental problem in quantum theory is to establish a connection between its local description (quantum field theory) and measurable quantities (particle masses, scattering amplitudes). In elementary particle physics one relies mostly on approximation techniques due to the non-integrable structure of the interactions. In order to gain a deeper understanding of quantum theory in general thes...
متن کامل2 Phase Transitions in Quantum Field Theory
In this lecture at a school for condensed matter physicist, I begin with basic concepts and tools for investigating phase transitions in quantum field theory. The very different roles of global and gauge symmetries in phase transitions will be elucidated. Among the important applications of the basic theory the thermodynamics of the electroweak transition is treated in detail, and the implicati...
متن کاملΓ-convergence for Nonlocal Phase Transitions
We discuss the Γ-convergence, under the appropriate scaling, of the energy functional ‖u‖Hs(Ω) + ∫ Ω W (u) dx, with s ∈ (0, 1), where ‖u‖Hs(Ω) denotes the total contribution from Ω in the Hs norm of u, and W is a double-well potential. When s ∈ [1/2, 1), we show that the energy Γ-converges to the classical minimal surface functional – while, when s ∈ (0, 1/2), it is easy to see that the functio...
