An exact string representation of 3d SU(2) lattice Yang--Mills theory
Florian Conrady, Igor Khavkine
We show that 3d SU(2) lattice Yang--Mills theory can be cast in the form of an exact string representation. The derivation starts from the exact dual (or spin foam) representation…
Dual Computations of Non-abelian Yang-Mills on the Lattice
J. Wade Cherrington, J. Daniel Christensen, Igor Khavkine
In the past several decades there have been a number of proposals for computing with dual forms of non-abelian Yang-Mills theories on the lattice. Motivated by the gauge-invariant,…
q-Deformed spin foam models of quantum gravity
Igor Khavkine, J. Daniel Christensen
We numerically study Barrett-Crane models of Riemannian quantum gravity. We have extended the existing numerical techniques to handle q-deformed models and arbitrary space-time tri…
Supercurrent in Nodal Superconductors
Igor Khavkine, Hae-Young Kee, Kazumi Maki
In recent years, a number of nodal superconductors have been identified; d-wave superconductors in high T_c cuprates, CeCoIn, and κ-(ET)_2Cu(NCS)_2, 2D f-wave superconductor in…
Formation of Electronic Nematic Phase in Interacting Systems
Igor Khavkine, Chung-Hou Chung, Vadim Oganesyan +1
We study the formation of an electronic nematic phase characterized by a broken point-group symmetry in interacting fermion systems within the weak coupling theory. As a function o…
