Real-space Imaging of Quantum Hall Quasiparticles
Jinghao Deng, Yiming Sun, Dimitri Pimenov +4
Quantum Hall systems host emergent quasiparticles with unusual charge, spin, and statistics, such as fractionally charged anyons. Although transport measurements have revealed many…
Dynamical Control of Superconductivity in Superconductor-Ferromagnet Bilayers
Dimitri Pimenov, Nicholas R. Poniatowski, Charlotte G. L. Bøttcher +2
We study a simplified model of a ferromagnetic metal proximitized by a fully-gapped wave superconductor and integrated with a microwave resonator. The low-energy excitations in…
Imaging propagating terahertz collective modes in two-dimensional semiconductor double layers
Andrew T. Pierce, Chirag Vaswani, Dimitri Pimenov +7
Two-dimensional transition metal dichalcogenide (TMD) semiconductors exhibit a wide range of novel phenomena at millielectronvolt (terahertz-frequency) energy scales, including sup…
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…
Bose-enhanced relaxation of driven atom-molecule condensates
Dimitri Pimenov, Erich J. Mueller
Motivated by recent experiments we study the interconversion between ultracold atomic and molecular condensates, quantifying the resulting oscillations and their slow decay. We fin…
Twists and turns of superconductivity from a repulsive dynamical interaction
Dimitri Pimenov, Andrey V. Chubukov
We review recent theoretical progress in understanding spatially uniform -wave superconductivity which arises from a fermion-fermion interaction, which is repulsive on the Matsu…
Odd-frequency pairing and time-reversal symmetry breaking for repulsive interactions
Dimitri Pimenov, Andrey V. Chubukov
We study the pairing of fermions by an interaction consisting of a Hubbard repulsion, mimicking a screened Coulomb potential, and a dynamical phonon-mediated attraction. For such i…
Quantum phase transition in a clean superconductor with repulsive dynamical interaction
Dimitri Pimenov, Andrey V. Chubukov
We consider a model of electrons at zero temperature, with a repulsive interaction which is a function of the energy transfer. Such an interaction can arise from the combination of…
Quasiparticle scattering in a superconductor near a nematic critical point: resonance mode and multiple attractive channels
Dimitri Pimenov, Alex Kamenev, Andrey V. Chubukov
We analyze the scattering rate for 2D fermions interacting via soft nematic fluctuations. The ground state is an s-wave superconductor, but other pairing channels are almost equall…
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…
