Emergent Chiral Symmetry: Parity and Time Reversal Doubles
There are numerous examples of approximately degenerate states of opposite parity in molecular physics. Theory indicates that these doubles can occur in molecules that are reflection-asymmetric. Such parity doubles occur in nuclear physics as well, among nuclei with odd A ∼ 219-229. We have also suggested elsewhere that such doubles occur in particle physics for baryons made up of cbu and cbd q...
متن کاملPseudo-parity-time symmetry in optical systems.
We introduce a novel concept of the pseudo-parity-time (pseudo-PT) symmetry in periodically modulated optical systems with balanced gain and loss. We demonstrate that whether or not the original system is PT symmetric, we can manipulate the property of the PT symmetry by applying a periodic modulation in such a way that the effective system derived by the high-frequency Floquet method is PT sym...
متن کاملGaussian noise and time-reversal symmetry in nonequilibrium Langevin models.
We show that in driven systems the Gaussian nature of the fluctuating force and time reversibility are equivalent properties. This result together with the potential condition of the external force drastically restricts the form of the probability distribution function, which can be shown to satisfy time-independent relations. We have corroborated this feature by explicitly analyzing a model fo...
متن کاملWave Transport Phenomena in Systems with Generalized Parity-Time Symmetry
In this thesis, we utilize the properties of scattering systems obeying anti-linear symmetries in order to produce novel wave transport phenomena. We first explore systems with delicately balanced gain and loss mechanisms, which are invariant under parity and time (PT ) reversal symmetry. Using equivalences between electronic network theory and photonic circuitry, we show that such structures c...
متن کاملThe time course of figure-ground reversal.
We report the results from five experiments employing a modified version of the short-term visual matching (STVM) method introduced by Driver and Baylis (1996). In STVM, participants see a study display with ambiguous figure-ground relations. After the study display, participants have to decide which of two shapes in a match display was seen before in the study display. STVM has been used by Ve...
