Bose-glass phases in disordered quantum magnets.

چکیده
In disordered spin systems with antiferromagnetic Heisenberg exchange, transitions into and out of a magnetic-field-induced ordered phase pass through unique regimes. Using quantum Monte Carlo simulations to study the zero-temperature behavior, these intermediate regions are determined to be Bose-glass phases. The localization of field-induced triplons causes a finite compressibility and, hence, glassiness in the disordered phase.

Probing the Bose-Glass–Superfluid Transition using Quantum Quenches of Disorder
We probe the transition between superfluid and Bose glass phases using quantum quenches of disorder in an ultracold atomic lattice gas that realizes the disordered Bose-Hubbard model. Measurements of excitations generated by the quench exhibit threshold behavior in the disorder strength indicative of a phase transition. Ab-initio quantum Monte Carlo simulations confirm that the appearance of ex...
متن کاملLuttinger-Liquid Physics and Bose-Einstein Condensation in Quantum Magnets
The phase diagram of quasi-1D arrays of quantum spins in temperature and magnetic field is particularly rich: quantum disordered, quantum critical, spin Luttinger-liquid, BEC, and classically saturated phases can in principle be studied [1-3]. However, model materials are rare, where these phases can be explored experimentally with the exception of the novel metal-organic compound (C5H12N)2CuBr...
متن کاملMetastable states in disordered Ising magnets in mean-field approximation
The mechanism of appearance of exponentially large number of metastable states in magnetic phases of disordered Ising magnets with short-range random exchange is suggested. It is based on the assumption that transitions into inhomogeneous magnetic phases results from the condensation of macroscopically large number of sparse delocalized modes near the localization threshold. The properties of m...
متن کاملUsing entanglement to discern phases in the disordered one-dimensional Bose-Hubbard model
We perform a matrix-product-state–based density matrix renormalisation group analysis of the phases for the disordered one-dimensional Bose-Hubbard model. For particle densities N/L = 1, 1/2 and 2 we show that it is possible to obtain a full phase diagram using only the entanglement properties, which come for free when performing an update. We confirm the presence of Mott insulating, superfluid...
متن کاملDisordered Quantum Solids
Due to the peculiar non-fermi liquid of one dimensional systems, disorder has particularly strong effects. We show that such systems belong to the more general class of disordered quantum solids. We discuss the physics of such disordered interacting systems and the methods that allows to treat them. In addition to, by now standard renormalization group methods, We explain how a simple variation...
