Viscochiral Transport: Chiral Selection of Hydrodynamic Vortices by Berry Curvature
Archisman Panigrahi, Khachatur Nazaryan
We predict a new viscochiral regime of electronic transport in which spatially varying Hall viscosity selects vortical flow patterns. Although uniform Hall viscosity cannot alter i…
Neural Flux Attachment: From Bose Condensates to Chiral Topological Matter
Rudik Badalyan, Khachatur G. Nazaryan, Tigran A. Sedrakyan
Can one neural wave function describe both a Bose condensate and a chiral topological liquid? We introduce ChernFormer, which combines a fermionic transformer with a fixed Chern-Si…
QERNEL: a Scalable Large Electron Model
Khachatur Nazaryan, Liang Fu
We introduce QERNEL, a foundational neural wavefunction that variationally solves families of parameterized many-electron Hamiltonians and captures their ground states throughout p…
Artificial Intelligence for Quantum Matter: Finding a Needle in a Haystack
Khachatur Nazaryan, Filippo Gaggioli, Yi Teng +1
Neural networks (NNs) have great potential in solving the ground state of various many-body problems. However, several key challenges remain to be overcome before NNs can tackle pr…
Is attention all you need to solve the correlated electron problem?
Max Geier, Khachatur Nazaryan, Timothy Zaklama +1
The attention mechanism has transformed artificial intelligence research by its ability to learn relations between objects. In this work, we explore how a many-body wavefunction an…
Magnonic Superconductivity
Khachatur G. Nazaryan, Liang Fu
We uncover a new superconducting state with partial spin polarization induced by a magnetic field. This state, which we call "magnonic superconductor", lacks a conventional pairing…
Terahertz amplification and lasing in pump-probe experiments with hyperbolic polaritons in h-BN
Khachatur G. Nazaryan, Ivan Ridkokasha, Marios H. Michael +1
We discuss terahertz pump-probe experiments in hBN from the perspective of Floquet optical materials and photonic time crystals. Anisotropic nature of this material results in a la…
Long distance electron-electron scattering detected with point contacts
Lev V. Ginzburg, Yuze Wu, Marc P. Röösli +15
We measure electron transport through point contacts in an electron gas in AlGaAs/GaAs heterostructures and graphene for a range of temperatures, magnetic fields and electron densi…
Low-temperature electron mobility in doped semiconductors with high dielectric constant
Khachatur G. Nazaryan, Mikhail Feigel'man
We propose and study theoretically a new mechanism of electron-impurity scattering in doped seminconductors with large dielectric constant. It is based upon the idea of \textit{vec…
Nonlocal conductivity, continued fractions and current vortices in electron fluids
Khachatur G. Nazaryan, Leonid Levitov
Vortices in electron fluids are a key indicator of electron hydrodynamics. However, a comprehensive framework linking macroscopic vorticity measurements with microscopic interactio…
Conductivity and thermoelectric coefficients of doped SrTiO at high temperatures
Kh. G. Nazaryan, M. V. Feigelman
We developed a theory of electric and thermoelectric conductivity of lightly doped SrTiO in the non-degenerate region , assuming that the major source of electr…
