MUTACO: Simulator-Efficient Response Matching in Stochastic Nonlinear Systems via Compatibility-Aware Sequential Design
Ege Karadeniz, İlter Onat Korkmaz, Umut Can Turhan +2
Many physical inverse problems are mediated by expensive stochastic simulators for which response gradients, adjoint sensitivities, or a differentiable simulator interface are unav…
Statistical Landscape Exploration and Weak-Field Defects in Selective Oscillator Ising Machines
Ömer Önder, Aydın Cem Keser
Oscillator Ising machines (OIMs) provide an analog dynamical approach to combinatorial optimization, but comparatively little is known about the statistical structure of the ensemb…
Effect of Josephson junction parameter spread on the performance of SQUID arrays
O. A. Nieves, M. A. Galí Labarias, A. C. Keser +2
Josephson junctions based on grain boundaries, such as those made of Yttrium Barium Copper Oxide (YBCO), exhibit inherent parameter spreads in their critical current and normal sta…
Tunable viscous layers in Corbino geometry using density junctions
Ramal Afrose, Aydin Cem Keser, Oleg Sushkov +1
In sufficiently clean materials where electron-electron interactions are strong compared to momentum-relaxing scattering processes, electron transport resembles the flow of a visco…
Driving Viscous Hydrodynamics in Bulk Electron Flow in Graphene Using Micromagnets
Jack N. Engdahl, Aydın Cem Keser, Thomas Schmidt +1
We consider the hydrodynamic flow of an electron fluid in a channel formed in a two-dimensional electron gas (2DEG) with no-slip boundary conditions. To generate vorticity in the f…
Magnetic response of a two-dimensional viscous electron fluid
Aydin Cem Keser, Oleg Sushkov
It has been established that the Coulomb interactions can transform the electron gas into a viscous fluid. This fluid is realized in a number of platforms, including graphene and t…
Micromagnets dramatically enhance effects of viscous hydrodynamic flow in two-dimensional electron fluid
Jack N. Engdahl, Aydin Cem Keser, Oleg P. Sushkov
The hydrodynamic behavior of electron fluids in a certain range of temperatures and densities is well established in graphene and in 2D semiconductor heterostructures. The hydrodyn…
Geometric control of universal hydrodynamic flow in a two dimensional electron fluid
Aydın Cem Keser, Daisy Q. Wang, Oleh Klochan +9
Fluid dynamics is one of the cornerstones of modern physics and has recently found applications in the transport of electrons in solids. In most solids electron transport is domina…
Nonlinear Quantum Electrodynamics in Dirac materials
Aydin C. Keser, Yuli Lyanda-Geller, Oleg P. Sushkov
Classical electromagnetism is linear. However, fields can polarize the vacuum Dirac sea, causing quantum nonlinear electromagnetic phenomena, e.g., scattering and splitting of phot…
Sign change in the anomalous Hall effect and strong transport effects in a 2D massive Dirac metal due to spin-charge correlated disorder
Aydin Cem Keser, Roberto Raimondi, Dimitrie Culcer
The anomalous Hall effect (AHE) is highly sensitive to disorder in the metallic phase. Here we show that statistical correlations between the charge and spin disorder sectors stron…
Analogue Stochastic Gravity in Strongly-Interacting Bose-Einstein Condensates
Aydin Cem Keser, Victor Galitski
Collective modes propagating in a moving superfluid are known to satisfy wave equations in a curved space time, with a metric determined by the underlying superflow. We use the Kel…
Dynamical many-body localization in an integrable model
Aydin Cem Keser, Sriram Ganeshan, Gil Refael +1
We investigate dynamical many-body localization and delocalization in an integrable system of periodically-kicked, interacting linear rotors. The Hamiltonian we investigate is line…
Long range -wave proximity effect into a disordered metal
Aydin Cem Keser, Valentin Stanev, Victor Galitski
We use quasiclassical methods of superconductivity to study the superconducting proximity effect from a topological -wave superconductor into a disordered one-dimensional metall…
Heating of Micro-protrusions in Accelerating Structures
A. C. Keser, T. M. Antonsen, G. S. Nusinovich +2
The thermal and field emission of electrons from protrusions on metal surfaces is a possible limiting factor on the performance and operation of high-gradient room temperature acce…
