A Lattice Chiral Boson Theory in d
Michael DeMarco, Ethan Lake, Xiao-Gang Wen
Chiral field theories describe large classes of matter, from the edges of Quantum Hall systems to the electroweak sector of the Standard Model, but defining them on the lattice has…
Quantum Information Science and Technology for Nuclear Physics. Input into U.S. Long-Range Planning, 2023
Douglas Beck, Joseph Carlson, Zohreh Davoudi +98
In preparation for the 2023 NSAC Long Range Plan (LRP), members of the Nuclear Science community gathered to discuss the current state of, and plans for further leveraging opportun…
Chiral Phases on the Lattice
Michael Austin DeMarco
While chiral quantum field theories (QFTs) describe a wide range of physical systems, from the standard model to topological quantum matter, the realization of chiral QFTs on a lat…
Topological Mott Insulators and Discontinuous -Terms
Michael A. DeMarco, Ethan Lake, Xiao-Gang Wen
We introduce a lattice field theory that describes the transition between a superfluid (SF) and a bosonic topological Mott Insulator (tMI) -- a symmetry protected topologica…
A Commuting Projector Model with a Non-zero Quantized Hall conductance
Michael DeMarco, Xiao-Gang Wen
By ungauging a recently discovered lattice rotor model for Chern-Simons theory, we create an exactly soluble path integral on spacetime lattice for Symmetry Protected Topo…
Lattice realization of compact Chern-Simons theory with exact 1-symmetries
Michael DeMarco, Xiao-Gang Wen
We propose a bosonic rotor model on a three dimensional space-time lattice. With the inclusion of a Maxwell term, we show that the low-energy semi-classical behavior of our…
A Single Right-Moving Free Fermion Mode on an Ultra-Local d Spacetime Lattice
Michael DeMarco, Xiao-Gang Wen
Defining a Chiral Fermion Theory on a lattice has presented an ongoing challenge both in Condensed Matter physics and in Lattice Gauge Theory. In this paper, we demonstrate that a…
A Novel Non-Perturbative Lattice Regularization of an Anomaly-Free Chiral Gauge Theory
Michael DeMarco, Xiao-Gang Wen
We present a numerical treatment of a novel non-perturbative lattice regularization of a Chiral Gauge Theory. Our approach follows recent proposals that exploit the…
Angular spin-orbit coupling in cold atoms
Michael DeMarco, Han Pu
We propose coupling two internal atomic states using a pair of Raman beams operated in Laguerre-Gaussian laser modes with unequal phase windings. This generates a coupling between…
Collapse of the hyperfine magnetic field at the Ru site in ferromagnetic rare earth intermetallics
D. Coffey, M. DeMarco, P. C. Ho +6
The Mössbauer Effect(ME) is frequently used to investigate magnetically ordered systems. One usually assumes that the magnetic order induces a hyperfine magnetic field, $B_{hyperfi…
