Random-mass disorder in the critical Gross-Neveu-Yukawa models
Hennadii Yerzhakov, Joseph Maciejko
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 sys…
Hyperbolic band theory
Joseph Maciejko, Steven Rayan
The notions of Bloch wave, crystal momentum, and energy bands are commonly regarded as unique features of crystalline materials with commutative translation symmetries. Motivated b…
Antiferromagnetic transitions of Dirac fermions in three dimensions
Yiqun Huang, Huaiming Guo, Joseph Maciejko +2
We use determinant quantum Monte Carlo (DQMC) simulations to study the role of electron-electron interactions on three-dimensional (3D) Dirac fermions based on the -flux model o…
Quantum phase transitions in Dirac fermion systems
Rufus Boyack, Hennadii Yerzhakov, Joseph Maciejko
A key problem in the field of quantum criticality is to understand the nature of quantum phase transitions in systems of interacting itinerant fermions, motivated by experiments on…
Critical properties of the valence-bond-solid transition in lattice quantum electrodynamics
Nikolai Zerf, Rufus Boyack, Peter Marquard +2
Elucidating the phase diagram of lattice gauge theories with fermionic matter in 2+1 dimensions has become a problem of considerable interest in recent years, motivated by physical…
