Planckian Bounds From Local Uncertainty Relations

Saurish Chakrabarty, Zohar Nussinov

We introduce ``local uncertainty relations'' in thermal many-body systems, from which fundamental bounds in quantum systems can be derived. These lead to universal non-relativistic…

Effect of Spreading Knowledge Centers -- A Physics-based Approach

Saurish Chakrabarty

We use a simple physics-inspired model to get an idea about how to enhance the speed with which a society becomes educated if we strategically place our knowledge spreading centers…

Quantum equilibration and measurements -- bounds on speeds, Lyapunov exponents, and transport coefficients obtained from the uncertainty relations and their comparison with experimental data

Saurish Chakrabarty, Zohar Nussinov

We discuss our recent study of local quantum mechanical uncertainty relations in quantum many body systems. These lead to fundamental bounds for quantities such as the speed, accel…

Exact Universal Chaos, Speed Limit, Acceleration, Planckian Transport Coefficient, "Collapse" to equilibrium, and Other Bounds in Thermal Quantum Systems

Zohar Nussinov, Saurish Chakrabarty

We introduce "local uncertainty relations" in thermal many body systems. Using these relations, we derive basic bounds. These results include the demonstration of universal non-rel…

Effect of heavy impurities on the dynamics of supercooled liquids

Saurish Chakrabarty, Ran Ni

We study the effect of heavy impurities on the dynamics of supercooled liquids. When a small fraction of particles in the supercooled liquid is made heavier, they exhibit slower dy…
