Energy-Modulated Time-Asymmetric Spontaneous Collapse: Forward-Backward Dynamics from Stochastic Ito Reversal and Bright Solitons
How quantum systems evolve differently forward and backward in time
Physicists have shown that quantum systems described by a particular mathematical framework cannot evolve the same way backward as forward in time—a fundamental asymmetry encoded in the ratio 2/3. When they modeled the behavior of ultracold lithium atoms using this framework, they found that collapse effects grew a trillion times stronger in the forward direction than the reverse, matching none of the symmetric collapse models currently used in physics.
This work bridges quantum mechanics and irreversibility—the reason we experience time flowing one direction. If validated experimentally in ultracold atom systems, it could reshape how physicists model quantum collapse and nonequilibrium processes, moving beyond the symmetric assumptions that have dominated the field for decades.
