Chiral Ising Gross-Neveu criticality of a single Dirac cone: A quantum Monte Carlo study
S. Mojtaba Tabatabaei, Amir-Reza Negari, Joseph Maciejko +1
We perform large-scale quantum Monte Carlo simulations of SLAC fermions on a two-dimensional square lattice at half filling with a single Dirac cone with spinor components an…
Automorphic Bloch theorems for hyperbolic lattices
Joseph Maciejko, Steven Rayan
Hyperbolic lattices are a new form of synthetic quantum matter in which particles effectively hop on a discrete tessellation of 2D hyperbolic space, a non-Euclidean space of unifor…
Surface Bogoliubov-Dirac cones and helical Majorana hinge modes in superconducting Dirac semimetals
Majid Kheirkhah, Zheng-Yang Zhuang, Joseph Maciejko +1
In the presence of certain symmetries, three-dimensional Dirac semimetals can harbor not only surface Fermi arcs, but also surface Dirac cones. Motivated by the experimental observ…
Strong-coupling corrections to hard domain walls in superfluid 3He-B
M. J. Rudd, P. Senarath Yapa, A. J. Shook +2
Domain walls in superfluid 3He-B have gained renewed interest in light of experimental progress on confining helium in nanofabricated geometries. Here, we study the effect of stron…
Crystallography of Hyperbolic Lattices
Igor Boettcher, Alexey V. Gorshkov, Alicia J. Kollár +3
Hyperbolic lattices are a revolutionary platform for tabletop simulations of holography and quantum physics in curved space and facilitate efficient quantum error correcting codes.…
Triangular pair density wave in confined superfluid He
Pramodh Senarath Yapa, Rufus Boyack, Joseph Maciejko
Recent advances in experiment and theory suggest that superfluid He under planar confinement may form a pair density wave (PDW) whereby superfluid and crystalline orders coexis…
LaN Structural and Topological Transitions Driven by Temperature and Pressure
Wei-Chih Chen, Chia-Min Lin, Joseph Maciejko +1
We study lanthanum mononitride LaN by first-principles calculations. The commonly reported rock-salt structure of symmetry for rare-earth monopnictides is found dynami…
Symmetry-breaking effects of instantons in parton gauge theories
G. Shankar, Joseph Maciejko
Compact quantum electrodynamics (CQED) with Dirac fermionic matter provides an adequate framework for elucidating the universal low-energy physics of a wide variety of (2+1)D s…
