Magnetic field induced quantum phase transitions in the two-impurity Anderson model

Conference Zhu, Lujun ; Zhu, Jian - Xin

In the two-impurity Anderson model, the inter-impurity spin exchange interaction favors a spin singlet state between two impurities leading to the localization of quasiparticles. We show that a local uniform magnetic field can delocalize the quasiparticies to restore the Kondo resonance. This transition is found to be continuous, accompanied by not only the divergence of the staggered (anti ferromagnetic) susceptibility, but also the divergence of the uniform spin susceptibility. This implies that the magnetic field induced quantum phase transitions in Kondo systems are in favor of the local critical type.

Magnetic-field-induced phase transition in a two-dimensional quantum magnet with plaquette distortion

Journal Article Val'kov, V. V., E-mail: vvv@iph.krasn.ru ; Mitskan, V A - Journal of Experimental and Theoretical Physics

Magnetic field effect on the structure of the ground state of a two-dimensional quantum Heisenberg magnet is analyzed. A plaquette representation is used to solve the self-consistent problem and calculate the collective excitation spectrum in a magnetic field. Conditions are found for quantum transition between non-magnetic and oblique antiferromagnetic phases. The change in the ground state of the system is associated with disappearance of the gap in the spin excitation spectrum. Effects of frustration and magnetic field on the spectrum are analyzed. A phase diagram of stable singlet and magnetically ordered phases is presented.

Quantum Phase Transition Induced by Magnetic Impurity

Journal Article Głodzik, Szczepan ; Ptok, Andrzej - Journal of Superconductivity and Novel Magnetism

The Yu–Shiba–Rusinov bound states can arise around magnetic impurities in conventional superconductors. Competition between screened and unscreened states can lead to the quantum phase transition. We discuss basic properties of this quantum phase transition in the case of the triangular lattice with on-site pairing. We show that the quantum phase transistion results from the change of the ground state of the system.

Theory of optical spectra in a magnetic field in doped semiconductor quantum wells: Impurity-induced broadening and transitions

Journal Article Lyo, S K - Physical Review (Section) B: Condensed Matter; (USA)

The effect of carrier-impurity interactions on luminescence- and excitation-spectroscopy line shapes and the Landau-level spectral density in a strong quantizing magnetic field is examined in modulation-doped semiconductor quantum wells. The line-shape function is obtained by summing the ladder diagrams,'' extending our previous one-rung'' approximation. Apart from yielding a line broadening, the carrier-impurity interaction is found to induce off-diagonal transitions (ODT) ({ital n}{r arrow}{ital n}{prime}; {ital n}{prime}{ne}{ital n}) between the Landau levels in the conduction and valence bands, breaking the usual {ital n}{r arrow}{ital n} selection rule. Here the first and second integers indicate the Landau quantum numbers in the conductionmore »« less

A quantum phase transition in a quantum external field: Superposing two magnetic phases

Journal Article Rams, Marek M. ; Zwolak, Michael ; Damski, Bogdan - Scientific Reports

We study an Ising chain undergoing a quantum phase transition in a quantum magnetic field. Such a field can be emulated by coupling the chain to a central spin initially in a superposition state. We show that – by adiabatically driving such a system – one can prepare a quantum superposition of any two ground states of the Ising chain. In particular, one can end up with the Ising chain in a superposition of ferromagnetic and paramagnetic phases – a scenario with no analogue in prior studies of quantum phase transitions. Remarkably, the resulting magnetization of the chain encodes themore »« less
