Two-point function of a $d = 2$ quantum critical metal in the limit $k_{F} \to \infty$ , $N_{f} \to 0$ with $N_{f} k_{F}$ fixed

Petter Säterskog, Balazs Meszena, Koenraad Schalm

We show that the fermionic and bosonic spectrum of $d = 2$ fermions at finite density coupled to a critical boson can be determined non-perturbatively in the combined limit $k_F\righ…

Non-perturbative emergence of non-Fermi liquid behaviour in $d = 2$ quantum critical metals

Balazs Meszena, Petter Säterskog, Andrey Bagrov +1

We consider the planar local patch approximation of $d = 2$ fermions at finite density coupled to a critical boson. In the quenched or Bloch-Nordsieck approximation, where one takes…

Holographic dual of a time machine

Irina Arefeva, Andrey Bagrov, Petter Saterskog +1

We apply the $A d S / C F T$ holography to the simplest possible eternal time machine solution in $A d S_{3}$ based on two conical defects moving around their center of mass along a circular…
