We study the zero temperature superfluid-insulator transition for a two-dimensional model of interacting, lattice bosons in the presence of quenched disorder and particle-hole symmetry. We follow the approach of a recent series of papers by Altman, Kafri, Polkovnikov, and Refael, in which the strong disorder renormalization group is used to study disordered bosons in one dimension. Adapting this method to two dimensions, we study several different species of disorder and uncover universal… Expand
Superfluid–insulator transition in weakly interacting disordered Bose gases: a kernel polynomial approach
An iterative scheme based on the kernel polynomial method is devised for the efficient computation of the one-body density matrix of weakly interacting Bose gases within Bogoliubov theory. ThisExpand
Superfluid density and compressibility at the superfluid-Mott glass transition
Systems of disordered interacting bosons with particle-hole symmetry can undergo a quantum phase transition between the superfluid phase and the Mott glass phase which is a gapless incompressibleExpand
Interplay of interactions and disorder at the superfluid-insulator transition: A dirty two-dimensional quantum critical point
We study the stability of the Wilson-Fisher fixed point of the quantum O(2N) vector model to quenched disorder in the large-N limit. While a random mass is strongly relevant at the Gaussian fixedExpand
Quantum critical behavior of a three-dimensional superfluid-Mott glass transition
The superfluid to insulator quantum phase transition of a three-dimensional particle-hole symmetric system of disordered bosons is studied. To this end, a site-diluted quantum rotor Hamiltonian isExpand
Superuid-Mott glass quantum multicritical point on a percolating lattice
We employ large-scale Monte Carlo simulations to study a particle-hole symmetric site-diluted quantum rotor model in two dimensions. The ground state phase diagram of this system features twoExpand
Critical properties of the superfluid-bose-glass transition in two dimensions.
The probability distribution of the SF response P(lnρSF) displays striking differences across the transition: while it narrows with increasing system sizes L in the SF phase, it broadens in the BG regime, indicating an absence of self-averaging, and at the critical point P(lrSF+zlnL) is scale invariant.

Random-mass disorder in the critical Gross-Neveu-Yukawa models
An important yet largely unsolved problem in the statistical mechanics of disordered quantum systems is to understand how quenched disorder affects quantum phase transitions in systems of itinerantExpand
Disordered fermionic quantum critical points
We study the effect of quenched disorder on the semimetal-superconductor quantum phase transition in a model of two-dimensional Dirac semimetal with $N$ flavors of two-component Dirac fermions, usingExpand
Strong disorder renormalization group primer and the superfluid–insulator transition
This brief review introduces the method and application of real-space renormalization group to strongly disordered quantum systems. The focus is on recent applications of the strong disorderExpand
Dynamical Conductivity Across The Disorder-Tuned Superconductor-Insulator Transition
A quantum phase transition is a dramatic event marked by large spatial and temporal fluctuations, where one phase of matter with its ground state and tower of excitations reorganizes into aExpand
