Despite the countless experimental confirmations, the Standard Model (SM) leaves many unanswered questions. Tensions have emerged over time between its predictions and experimental data, mostly in the flavor sector. For these reasons, a theory capable to account at least partially for the observed discrepancies is actively sought for.
Notable examples in the exploration of physics beyond...
A powerful way to study quantum systems is through their symmetries, or equivalently, the conserved quantities associated with the Hamiltonian. Standard quantum mechanics tells us that these correspond to operators commuting with the Hamiltonian. Once the Hamiltonian is known, its conserved quantities can, at least in principle, be identified.
However, only those symmetries that persist under...
In this work, we combine coarse-grained Brownian dynamics simulations and mean-field theory to study supercoiling dynamics, as well as the steady-state profiles of twist and writhe, in an open DNA polymer where one of the free ends is subjected to a constant torque. Even though the other end is free, and hence can spin and release torsional stress, we observe that the entire chain transitions...
