Influence of Harris disorder on quantum-critical superconductivity
Serhii Kryhin, Peter Lunts, Aavishkar A. Patel +2
In the Hertz theory, a quantum critical metal is described by the coupling of a Fermi surface to fluctuations of a Landau-damped bosonic field , which may represent either an or…
Completely-positive non-signalling non-Markovian dynamics
Serhii Kryhin, Vivishek Sudhir
We define non-Markovian quantum dynamics as evolution in which the current state depends on all past states, and completely characterize its structure under the assumptions of comp…
Forecasting in the presence of scale-free noise
Serhii Kryhin, Tatiana Mouzykantskii, Vivishek Sudhir
The extraction of signals from noise is a common problem in all areas of science and engineering. A particularly useful version is that of forecasting: determining a causal filter…
Strong non-linear response of strange metals
Serhii Kryhin, Subir Sachdev, Pavel A. Volkov
We show that nonlinear transport responses in strange metals are strong, larger by a factor of than in Fermi liquids. Within the two-dimensional Yukawa-Sachdev-Ye-Kitaev mo…
Linear-in-temperature conductance in two-dimensional electron fluids
Serhii Kryhin, Qiantan Hong, Leonid Levitov
Linear temperature dependence of transport coefficients in metals is often ascribed to non-Fermi-liquid physics. Here we demonstrate the -linear behavior of nonlocal conductivit…
Distinguishable consequence of classical gravity on quantum matter
Serhii Kryhin, Vivishek Sudhir
What if gravity is classical? If true, a consistent co-existence of classical gravity and quantum matter requires that gravity exhibit irreducible fluctuations. These fluctuations…
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…
Two-dimensional electron gases as non-Newtonian fluids
Serhii Kryhin, Leonid Levitov
Two-dimensional electron systems offer an appealing platform to explore long-lived excitations arising due to collinear carrier scattering enabled by phase-space constraints at the…
Degeneracy Engineering for Classical and Quantum Annealing: A Case Study of Sparse Linear Regression in Collider Physics
Eric R. Anschuetz, Lena Funcke, Patrick T. Komiske +2
Classical and quantum annealing are computing paradigms that have been proposed to solve a wide range of optimization problems. In this paper, we aim to enhance the performance of…
Disentangling Quarks and Gluons with CMS Open Data
Patrick T. Komiske, Serhii Kryhin, Jesse Thaler
We study quark and gluon jets separately using public collider data from the CMS experiment. Our analysis is based on 2.3/fb of proton-proton collisions at 7 TeV, collected at the…
Collinear scattering and long-lived excitations in two-dimensional electron fluids
Serhii Kryhin, Leonid Levitov
For a long time, it has been thought that 2D Fermi gases could support long-lived excitations, thanks to the collinear quasiparticle scattering controlled by phase space constraint…
Thermorefringent noise in crystalline optical materials
Serhii Kryhin, Evan D. Hall, Vivishek Sudhir
Any material in thermal equilibrium exhibits fundamental thermodynamic fluctuations of its mechanical and optical properties. Such thermodynamic fluctuations of length, elastic con…
