We report on numerically exact determinantal quantum Monte Carlo simulations of the onset
of spin-density-wave (SDW) order in itinerant electron systems captured by a sign-problem …

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 due to the …

We study the antiferromagnetic quantum critical metal in 3− ε space dimensions by
extending the earlier one-loop analysis [Sur and Lee, Phys. Rev. B 91, 125136 (2015) …

In light of the new experimental and theoretical important developments in high-T c
superconductivity, we revisit the fermionic hot-spot model relevant to the phenomenology of …

We review the recent developments in the field of cuprate superconductors with special
focus on the recently observed charge order in the underdoped compounds. We introduce …

In metals, low-energy effective theories are characterized by a set of coupling functions.
Among them, the angle-dependent Fermi momentum specifies the size and shape of Fermi …

We study the field theory for the SU (N c) symmetric antiferromagnetic quantum critical metal
with a one-dimensional Fermi surface embedded in general space dimensions between two …

The two-loop renormalization group (RG) calculation is considerably extended here for the
two-dimensional (2D) fermionic effective field theory model, which includes only the so …

We show that anisotropic quantum corrections can dynamically give rise to curved
momentum-spacetimes for quasiparticles in metals. In the (2+ 1)-dimensional …

We perform the calculation of the dc resistivity as a function of temperature of the “strange-
metal” state that emerges in the vicinity of a spin-density-wave phase transition in the …
