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…
