Bridging the Quantum and Classical Worlds

10.11.2025 by pricpr

A system’s interaction with both classical and quantum environments inevitably introduces competing timescales—here, a hybrid Redfield-MASH method acknowledges this by treating nonadiabatic coupling to classical degrees of freedom distinctly from secular dissipation into a Markovian quantum bath, a distinction that foreshadows the inevitable emergence of unpredictable behavior.

A new method accurately simulates the interplay between quantum and classical dynamics in complex molecular systems.

Twisting Reality: Quantum Control Through Surface Geometry

A finite section of twisted cylinder, embedded within an infinite free space, presents a scattering problem wherein interactions are dictated by the geometry of this bounded region.

New research reveals how manipulating the shape of a surface can subtly alter quantum wavefunctions without changing their energy.

Beyond Equilibrium: When Measurement Changes Everything

The two-dimensional coarse-grained dissipative hydrodynamics model (CDHM) utilizes a square lattice structure where strong couplings, denoted by thick red bonds, define interactions with a strength of <i>gg</i>, differentiating them from the remaining bonds with unit strength.

New research reveals how continuous observation can drive phase transitions in quantum systems, even without external forces.
