Noise and Controllability: suppression of controllability in large quantum systems
Michael Khasin, Ronnie Kosloff
A closed quantum system is defined as completely controllable if an arbitrary unitary transformation can be executed using the available controls. In practice, control fields are a…
Spectrum of an oscillator with jumping frequency and the interference of partial susceptibilities
M. I. Dykman, M. Khasin, J. Portman +1
We study an underdamped oscillator with shot-noise frequency fluctuations. The oscillator spectrum is determined by the interference of the susceptibilities for different eigenfreq…
Speeding up disease extinction with a limited amount of vaccine
M. Khasin, M. I. Dykman, B. Meerson
We consider optimal vaccination protocol where the vaccine is in short supply. In this case, disease extinction results from a large and rare fluctuation. We show that the probabil…
Time-resolved extinction rates of stochastic populations
Michael Khasin, Baruch Meerson, Pavel V. Sasorov
Extinction of a long-lived isolated stochastic population can be described as an exponentially slow decay of quasi-stationary probability distribution of the population size. We ad…
Extinction rate fragility in population dynamics
M. Khasin, M. I. Dykman
Population extinction is a rare event which requires overcoming an effective barrier. We show that the extinction rate can be fragile: a small change in the system parameters leads…
