Superconductivity via paramagnon and magnon exchange in a 2D near-ferromagnetic full metal and ferromagnetic half-metal
Zachary M Raines, Andrey V Chubukov
We study superconductivity in paramagnetic and ferromagnetically-ordered phases in a two-dimensional electron system with parabolic fermionic dispersion and short-range repulsive i…
Superconductivity induced by spin-orbit coupling in a two-valley ferromagnet
Zachary M Raines, Andrey V Chubukov
We analyze the origin of superconductivity in a ferromagnetically ordered state of multi-layer graphene systems placed in proximity to WSe. We model these materials by a two-va…
Two-dimensional Stoner transitions beyond mean-field
Zachary M. Raines, Andrey V. Chubukov
We have previously shown that the Stoner instability 2D has unconventional behavior: it is strongly first order but features a susceptibility which diverges at the transition point…
Unconventional discontinuous transitions in a 2D system with spin and valley degrees of freedom
Zachary M. Raines, Leonid I. Glazman, Andrey V. Chubukov
We analyze the transition into the most favorable ordered state for a system of 2D fermions with spin and valley degrees of freedom. We show that for a range of rotationally invari…
Unconventional discontinuous transitions in isospin systems
Zachary M. Raines, Leonid I. Glazman, Andrey V. Chubukov
We show that two-dimensional fermions with dispersion or undergo a first-order Stoner transition to a fully spin-polarized state despite that the spin susceptibility di…
Applicability of Eliashberg theory for systems with electron-phonon and electron-electron interaction: a comparative analysis
Shang-Shun Zhang, Zachary M. Raines, Andrey V. Chubukov
We present a comparative analysis of the validity of Eliashberg theory for the cases of fermions interacting with an Einstein phonon and with soft nematic fluctuations near an Isin…
Superfluid stiffness within Eliashberg theory: the role of vertex corrections
Zachary M. Raines, Shang-Shun Zhang, Andrey V. Chubukov
In this work we consider the superfluid stiffness of a generically non-Galilean invariant interacting system and investigate under what conditions the stiffness may nonetheless app…
Disorder in Andreev reflection of a quantum Hall edge
Vladislav D. Kurilovich, Zachary M. Raines, Leonid I. Glazman
We develop a theory of charge transport along the quantum Hall edge proximitized by a "dirty" superconductor. Disorder randomizes the Andreev reflection rendering the conductance o…
Spin-valley Silin modes in graphene with substrate-induced spin-orbit coupling
Zachary M. Raines, Dmitrii L. Maslov, Leonid I. Glazman
In the presence of external magnetic field the Fermi-liquid state supports oscillatory spin modes known as Silin modes. We predict the existence of the generalized Silin modes in a…
Spin-valley collective modes of the electron liquid in graphene
Zachary M. Raines, Vladimir I. Fal'ko, Leonid I. Glazman
We develop the theory of collective modes supported by a Fermi liquid of electrons in pristine graphene. Under reasonable assumptions regarding the electron-electron interaction, a…
Optical Enhancement of Superconductivity via Targeted Destruction of Charge Density Waves
Hossein Dehghani, Zachary M. Raines, Victor M. Galitski +1
It has been experimentally established that the occurrence of charge density waves is a common feature of various under-doped cuprate superconducting compounds. The observed states…

Exciting new work on Bi2212 shows the presence of non-trivial spin-orbit coupling effects as seen in spin resolved ARPES data [Gotlieb et al., Science, 362, 1271-1275 (2018)]. Moti…

Jonathan B. Curtis, Zachary M. Raines, Andrew A. Allocca +2
Driving a conventional superconductor with an appropriately tuned classical electromagnetic field can lead to an enhancement of superconductivity via a redistribution of the quasip…
Enriched axial anomaly in Weyl materials
Zachary Raines, Victor Galitski
While quantum anomalies are often associated with the breaking of a classical symmetry in the quantum theory, their anomalous contributions to observables remain distinct and well-…
Hybridization of Higgs modes in a bond-density-wave state in cuprates
