Weakly interacting Bose-Einstein condensate with stochastic resetting
Nikhil Mesquita, Manas Kulkarni, Satya N. Majumdar +1
Stochastic resetting can generate strong correlations in many-body systems through a shared fluctuating environment. Here, we investigate how such dynamically emergent correlations…
Quantum resetting with memory
Gabriele de Mauro, Manas Kulkarni, Satya N. Majumdar
We introduce a quantum stochastic resetting protocol with uniform memory, in which each resetting event returns the system to a state visited at a time chosen uniformly from its en…
Control transition in a temporally random classical spin chain
Elisha Shmalo, J. H. Pixley, Manas Kulkarni +2
We theoretically explore a phase transition between controlled and chaotic dynamics in a classical spin chain model subject to chaotic Hamiltonian dynamics and a contractive "contr…
Sluggish quantum mechanics of noninteracting fermions with spatially varying effective mass
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We analyze a class of one-dimensional quantum systems characterized by a position-dependent kinetic term arising as the continuum limit of an inhomogeneous tight-binding model with…
Diffraction and pseudospectra in non-Hermitian quasiperiodic lattices
Ananya Ghatak, Dimitrios H. Kaltsas, Manas Kulkarni +1
Wave dynamics in disordered open media is an intriguing topic, and has lately attracted a lot of attention in non-Hermitian physics, especially in photonics. In fact, spatial distr…
