Fuzzy gauge theory for quantum computers
Andrei Alexandru, Paulo F. Bedaque, Andrea Carosso +3
Continuous gauge theories, because of their bosonic degrees of freedom, have an infinite-dimensional local Hilbert space. Encoding these degrees of freedom on qubit-based hardware…
Magnetic polarizability of a charged pion from four-point functions in lattice QCD
Frank X. Lee, Walter Wilcox, Andrei Alexandru +1
Electromagnetic dipole polarizabilities are fundamental properties of a hadron that represent its resistance to deformation under external fields. For a charged hadron, the presenc…
Separation of Infrared and Bulk in Thermal QCD
Xiao-Lan Meng, Peng Sun, Andrei Alexandru +4
A new thermal regime of QCD, featuring decoupled scale-invariant infrared glue, has been proposed to exist both in pure-glue (N=0) and ``real-world" (N=2+1 at physical quar…
Nucleon Electric Dipole Moment from the Term with Lattice Chiral Fermions
Jian Liang, Andrei Alexandru, Terrence Draper +4
We calculate the nucleon electric dipole moment (EDM) from the term with overlap fermions on three domain wall lattices with different sea pion masses at lattice spacing 0.11 f…
Charged pion electric polarizability from four-point functions in lattice QCD
Frank X. Lee, Andrei Alexandru, Chris Culver +1
Polarizabilities reveal valuable information on the internal structure of hadrons in terms of charge and current distributions. For neutral hadrons, the standard approach is the ba…
On the Infinite Variance Problem in Fermion Models
Andrei Alexandru, Paulo Bedaque, Andrea Carosso +1
Monte Carlo calculations of fermionic systems with continuous auxiliary fields frequently suffer from a diverging variance. If a system has the infinite variance problem, one canno…
