Orbital Kondo spectroscopy in a double quantum dot system
We calculate the nonequilibrium conductance of a system of two capacitively coupled
quantum dots, each one connected to its own pair of conducting leads. The system has been …

Heavy antiferromagnetic phases in Kondo lattices
L Isaev, I Vekhter - Physical Review Letters, 2013 - APS
We propose a microscopic physical mechanism that stabilizes the coexistence of the Kondo
effect and antiferromagnetism in heavy-fermion systems. We consider a two-dimensional …

Berezinskii–Kosterlitz–Thouless transition through the eyes of duality
G Ortiz, E Cobanera, Z Nussinov - 40 Years of Berezinskii–Kosterlitz …, 2013 - World Scientific
A new “bond-algebraic” approach to duality transformations provides a very powerful
technique to analyze elementary excitations in the classical two-dimensional XY and p-clock …

Exact real-space renormalization method and applications
We present a numerical method based on real-space renormalization that outputs the exact
ground space of “frustration-free” Hamiltonians. The complexity of our method is polynomial …
