The Hubbard model on the Bethe lattice via variational uniform tree states: metal-insulator transition and a Fermi liquid
Peter Lunts, Antoine Georges, E. Miles Stoudenmire +1
We numerically solve the Hubbard model on the Bethe lattice with finite coordination number , and determine its zero-temperature phase diagram. For this purpose, we introduce…

Many-body chaos in the antiferromagnetic quantum critical metal
Peter Lunts, Aavishkar A. Patel
We compute the scrambling rate at the antiferromagnetic (AFM) quantum critical point, using the fixed point theory of Phys. Rev. X , 021010 (2017). At this strongly…

Noncommutativity between the low-energy limit and integer dimension limits in the -expansion: a case study of the antiferromagnetic quantum critical metal
Andres Schlief, Peter Lunts, Sung-Sik Lee
We study the field theory for the SU() symmetric antiferromagnetic quantum critical metal with a one-dimensional Fermi surface embedded in general space dimensions between two…
