Dual QED3 at "NF = 1/2" is an interacting CFT in the infrared
Dietrich Roscher, Emilio Torres, Philipp Strack
We study the fate of weakly coupled dual QED3 in the infrared, that is, a single two-component Dirac fermion coupled to an emergent U(1) gauge field, but without Chern-Simons term.…
Universality in antiferromagnetic strange metals
Stefan A. Maier, Philipp Strack
We propose a theory of metals at the spin-density wave quantum critical point in spatial dimension . We provide a first estimate of the full set of critical exponents (dynamic…
Hyperscaling at the spin density wave quantum critical point in two dimensional metals
Aavishkar A. Patel, Philipp Strack, Subir Sachdev
The hyperscaling property implies that spatially isotropic critical quantum states in spatial dimensions have a specific heat which scales with temperature as , and an…
FFLO strange metal and quantum criticality in two dimensions: theory and application to organic superconductors
Francesco Piazza, Wilhelm Zwerger, Philipp Strack
Increasing the spin imbalance in superconductors can spatially modulate the gap by forming Cooper pairs with finite momentum. For large imbalances compared to the Fermi energy, the…
Stress tensor and current correlators of interacting conformal field theories in 2+1 dimensions: Fermionic Dirac matter coupled to U(1) gauge field
Yejin Huh, Philipp Strack
We compute the central charge and universal conductivity of fermions coupled to a gauge field up to next-to-leading order in the expansion. We disc…
Vector boson excitations near deconfined quantum critical points
Yejin Huh, Philipp Strack, Subir Sachdev
We show that the Néel states of two-dimensional antiferromagnets have low energy vector boson excitations in the vicinity of deconfined quantum critical points. We compute the univ…
