Nonreciprocal Chiral Automata
Andrew A. Allocca, Armin Rahmani, Pouyan Ghaemi +1
Odd pressure is a parity-odd transport coefficient that gives an isotropic pressure response to vorticity in compressible two-dimensional fluids. By asymmetrically coupling vortica…
Lindbladian quantization of mechanical systems with nonholonomic constraints
Daniel Schubring, Sriram Ganeshan
Nonholonomic mechanics describes systems subject to non-integrable velocity constraints, such as rolling bodies and skating motion. These systems generally lack a canonical Hamilto…
Odd fluids from chiral cellular automata
Andrew A. Allocca, Shiva Heidari, Thomas Iadecola +3
Cellular automata are discrete dynamical systems defined on a lattice, in which each site carries a finite set of states that evolve in time according to local deterministic rules.…
Measurement and feedback-driven adaptive dynamics in the classical and quantum kicked top
Mahaveer Prasad, Ahana Chakraborty, Thomas Iadecola +4
In classical dynamical systems, stochastic feedback can stabilize otherwise unstable periodic orbits, giving rise to distinct controlled and uncontrolled phases as the rate of cont…
Quantum geometry of the rotating shallow water model
Sriram Ganeshan, Alan T. Dorsey
The rotating shallow water equations (RSWE) are a mainstay of atmospheric and oceanic modeling, and their wave dynamics has close analogues in settings ranging from two-dimensional…
