Emergence of curved momentum-spacetime and its effect on the cyclotron motion in the antiferromagnetic quantum critical metal
Francisco Borges, Sung-Sik Lee
We show that anisotropic quantum corrections can dynamically give rise to curved momentum-spacetimes for quasiparticles in metals. In the (2+1)-dimensional antiferromagnetic quantu…
Fermi liquids beyond the forward scattering limit: the role of non-forward scatterings for scale invariance and instabilities
Han Ma, Sung-Sik Lee
Landau Fermi liquid theory is a fixed point theory of metals that includes the forward scattering amplitudes as exact marginal couplings. However, the fixed point theory that only…
Massless graviton in a model of quantum gravity with emergent spacetime
Sung-Sik Lee
In the model of quantum gravity proposed in JHEP 2020, 70 (2020), dynamical spacetime arises as a collective phenomenon of underlying quantum matter. Without a preferred decomposit…
Field-theoretic functional renormalization group formalism for non-Fermi liquids and its application to the antiferromagnetic quantum critical metal in two dimensions
Francisco Borges, Anton Borissov, Ashutosh Singh +2
To capture the universal low-energy physics of metals within effective field theories, one has to generalize the usual notion of scale invariance and renormalizable field theory du…
Ultraviolet-Infrared Mixing in Marginal Fermi Liquids
Weicheng Ye, Sung-Sik Lee, Liujun Zou
When Fermi surfaces (FSs) are subject to long-range interactions that are marginal in the renormalization-group sense, Landau Fermi liquids are destroyed, but only barely. With the…
Constraints on beta functions in field theories
Han Ma, Sung-Sik Lee
The -functions describe how couplings run under the renormalization group flow in field theories. In general, all couplings that respect the symmetry and locality are generated…
