Physical Review A

Maximum-entropy approach to critical phenomena in ground states of finite systems

Abstract

A scheme for detecting signatures of phase transitions associated with pure quantum states, from the knowledge of a limited set of expectation values, is introduced. An accurate prediction of critical regions in ground states of systems with a finite number of particles is obtained.

Ground-state wave functions and maximum entropy

N. Canosa, Angel Ricardo Plastino, R. Rossignoli

A modified version of the maximum-entropy principle is applied to distributions associated with special quantum states. In this way, it becomes feasible to make statistical inferences concerning the ground-state wave function and the associated potential from the sole knowledge of a few relevant mean values. The scheme is illustrated for the case of anharmonic and Morse potentials and yields excellent results.

Quantum phase transitions in finite systems

Clare Dunning, Katrina Hibberd, Jon Links

The aim of this work is to develop a technique for identifying quantum phase transitions which does not rely on the existence of a thermodynamic limit, for studies in finite systems. The approach we adopt exploits an exact mapping of the spectrum of a many-body integrable system, which admits an exact Bethe ansatz solution, into the quasi-exactly solvable spectrum of a one-particle Schrodinger operator. Bifurcations of the minima for the potential of the Schrodinger operator determine critical ground-state couplings. By considering the behaviour of certain ground-state correlation functions, these may be identified as quantum phase transitions in the many-body integrable system with finite particle number. We study two particular examples of bosonic Hamiltonians which admit second-order transitions, and discuss further applications.

Quantum information and quantum phase transitions in atom–molecule conversion systems

Zheng-Da Hu, Wei Zhong, Jicheng Wang +2 more

Quantum phase transition is a fundamental physical phenomenon in a quantum many-body system. This work aims to explore the quantum phase transition in an atom–molecule conversion system through quantum information tools. We show that the ground state of the system undergoes significant changes in the quantum critical region, with both atomic number fluctuation and the quantum information embedded in the ground state exhibiting drastic alterations. As the rescaled phase transition parameter increases, the atomic state sharply transits into the molecular state in the critical region. Even for finite total number, the phase transition point can be accurately predicted through finite-size scaling laws. Our study confirms that the finite-size scaling analysis based on quantum coherence and quantum Fisher information is a reliable method for studying critical phenomena in the atom–molecule system from a quantum information perspective.

Quantum Phase Transitions in a Finite System

A general procedure for studying finite-N effects in quantum phase transitions of finite systems is presented and applied to the critical-point dynamics of nuclei undergoing a shape-phase transition of second-order (continuous), and of first-order with an arbitrary barrier.

The Critical Point Entanglement and Chaos in the Dicke Model

Lina Bao, Feng Pan, Jing Lu +1 more

Ground state properties and level statistics of the Dicke model for a finite number of atoms are investigated based on a progressive diagonalization scheme (PDS). Particle number statistics, the entanglement measure and the Shannon information entropy at the resonance point in cases with a finite number of atoms as functions of the coupling parameter are calculated. It is shown that the entanglement measure defined in terms of the normalized von Neumann entropy of the reduced density matrix of the atoms reaches its maximum value at the critical point of the quantum phase transition where the system is most chaotic. Noticeable change in the Shannon information entropy near or at the critical point of the quantum phase transition is also observed. In addition, the quantum phase transition may be observed not only in the ground state mean photon number and the ground state atomic inversion as shown previously, but also in fluctuations of these two quantities in the ground state, especially in the atomic inversion fluctuation.
