Polaron spectra and edge singularities for correlated flat bands
Dimitri Pimenov
Single- and two-particle spectra of a single immobile impurity immersed in a fermionic bath can be computed exactly and are characterized by divergent power laws (edge singularitie…
One-dimensional scattering of two-dimensional fermions near quantum criticality
Dimitri Pimenov, Alex Kamenev, Andrey V. Chubukov
Forward and backscattering play an exceptional role in the physics of two-dimensional interacting fermions. In a Fermi liquid, both give rise to a non-analytic form o…
Incommensurate density wave quantum criticality in two dimensional metals
Johannes Halbinger, Dimitri Pimenov, Matthias Punk
We revisit the problem of two dimensional metals in the vicinity of a quantum phase transition to incommensurate charge density wave order, where the order parame…
Spectra of heavy polarons and molecules coupled to a Fermi sea
Dimitri Pimenov, Moshe Goldstein
We study the spectrum of an impurity coupled to a Fermi sea (e.g., minority atom in an ultracold gas, exciton in a solid) by attraction strong enough to form a molecule/trion. We i…
Non-Fermi liquid at the FFLO quantum critical point
Dimitri Pimenov, Ipsita Mandal, Francesco Piazza +1
When a 2D superconductor is subjected to a strong in-plane magnetic field, Zeeman polarization of the Fermi surface can give rise to inhomogeneous FFLO order with a spatially modul…
Fermi-edge exciton-polaritons in doped semiconductor microcavities with finite hole mass
Dimitri Pimenov, Jan von Delft, Leonid Glazman +1
The coupling between a 2D semiconductor quantum well and an optical cavity gives rise to combined light-matter excitations, the exciton-polaritons. These were usually measured when…
Deconfined quantum criticality in SU(3) antiferromagnets on the triangular lattice
Dimitri Pimenov, Matthias Punk
We propose field theories for a deconfined quantum critical point in antiferromagnets on the triangular lattice. In particular we consider the continuous transition between…
