New theoretical physics research introduces a simulation method of machine-learning-based effective Hamiltonian for ...

ABSTRACT: We examined the fractional second-order singular Lagrangian systems. We wrote the action principal function and equations of motion as fractional total differential equations. Also, we ...

Quantum mechanics is the study of the dynamics of particles at its most fundamental level. The state of a particle, such as its position or momentum, is described by a statistical distribution ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature.

The study analyzed the XY model governed by Hamiltonian equations of motion examining a two-dimensional spin particle ... In addition to illuminating the behavioral mechanics of collectives in ...

What Drives Us in Mechanical Engineering? Mechanical engineers use the principles of energy, materials, and mechanics to design and manufacture machines and devices of all types. At Drexel, our ...
