Review on novel methods for lattice gauge theories

MC Banuls, K Cichy - Reports on Progress in Physics, 2020 - iopscience.iop.org
Formulating gauge theories on a lattice offers a genuinely non-perturbative way of studying
quantum field theories, and has led to impressive achievements. In particular, it significantly …

Weak commutation relations and eigenvalue statistics for products of rectangular random matrices

JR Ipsen, M Kieburg - Physical Review E, 2014 - APS
We study the joint probability density of the eigenvalues of a product of rectangular real,
complex, or quaternion random matrices in a unified way. The random matrices are …

Singular values of the Dirac operator in dense QCD-like theories

T Kanazawa, T Wettig, N Yamamoto - Journal of High Energy Physics, 2011 - Springer
A bstract We study the singular values of the Dirac operator in dense QCD-like theories at
zero temperature. The Dirac singular values are real and nonnegative at any nonzero quark …

Products of independent quaternion Ginibre matrices and their correlation functions

JR Ipsen - Journal of Physics A: Mathematical and Theoretical, 2013 - iopscience.iop.org
We discuss the product of independent induced quaternion (β= 4) Ginibre matrices, and the
eigenvalue correlations of this product matrix. The joint probability density function for the …

Dirac spectrum in complex Langevin simulations of QCD

K Splittorff - Physical Review D, 2015 - APS
We show that the spectrum of the Dirac operator in complex Langevin simulations of QCD at
nonzero chemical potential must behave in a way which is radically different from the one in …

Finite-density massless two-color QCD at the isospin Roberge-Weiss point and the't Hooft anomaly

T Furusawa, Y Tanizaki, E Itou - Physical Review Research, 2020 - APS
We study the phase diagram of two-flavor massless two-color QCD (QC 2 D) under the
presence of quark chemical potentials and imaginary isospin chemical potentials. At the …

Dirac spectrum of one-flavor QCD at and continuity of the chiral condensate

JJM Verbaarschot, T Wettig - Physical Review D, 2014 - APS
We derive exact analytical expressions for the spectral density of the Dirac operator at fixed
θ-angle in the microscopic domain of one-flavor QCD. These results are obtained by …

Banks-Casher-type relation for the BCS gap at high density

T Kanazawa, T Wettig, N Yamamoto - The European Physical Journal A, 2013 - Springer
We derive a new Banks-Casher-type relation which relates the density of complex Dirac
eigenvalues at the origin to the BCS gap of quarks at high density and zero temperature. Our …

Random matrix model for the QCD Kondo effect

T Kanazawa - arXiv preprint arXiv:2006.00200, 2020 - arxiv.org
We propose a novel random matrix model that describes the QCD Kondo effect. The model
correctly implements both the chiral symmetry of light quarks and the $\mathrm {SU}(2) …
