DOI: 10.1002/rnc.7827
Abstract: This paper explores the design of a composite prescribed‐time controller for two‐time‐scale systems (TTSSs). First, due to numerical issues caused by the small perturbation parameter, standard control design techniques for prescribed‐time stabilization of regular linear… read more here.

DOI: 10.1007/s00440-019-00901-9
Abstract: We study the two-time distribution in directed last passage percolation with geometric weights in the first quadrant. We compute the scaling limit and show that it is given by a contour integral of a Fredholm… read more here.

DOI: 10.1007/s11005-024-01880-2
Abstract: We consider a protocol for the two-time measurement of entropic observables in quantum open systems driven out of thermal equilibrium by coupling to several heat baths. We concentrate on the Markovian approximation of the time-evolution… read more here.
