Quantum van der Pol oscillators are driven-dissipative systems displaying quantum synchronization phenomena. When forced by a squeezed drive, the frequency adjusts to half of forcing multiple preferred phases. Here we analyze physical origin this entrained response, establishing connection with metastability in open systems. We report dynamical regime characterized huge separation time scales, ...

The existence and limits of metastable droplets have been calculated using finite-system renormalization-group theory, for q-state Potts models in spatial dimension d=3. dependence the droplet critical sizes on magnetic field, temperature, number states q has calculated. same method also used calculation hysteresis loops across first-order phase transitions these systems. loop shapes deduced as...

Assembly of the OmpF and LamB proteins was kinetically retarded in deep rough lipopolysaccharide mutants of Escherichia coli K-12. OmpF assembly was affected at the step of conversion of metastable trimers to stable trimers, whereas LamB assembly was influenced both at the monomer-to-metastable trimer and metastable-to-stable trimer steps. These assembly defects were reversed in the presence of...

The synchronization of asynchronous signals can lead to metastable behavior and malfunction of digital circuits. It is believed but not proved that metastability principally cannot be avoided. Confusion exists about its practical importance. This paper shows that metastable behavior can be avoided by usage of quantum synchronizers in principle, but not in practice, and that conventional synchro...

Six solid phases of [Mn(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry. The phase transitions were found between the following solid phases: stable KIc ↔ stable KIb at TC5 = 225 K, metastable KIII ↔ metastable KII at TC4 = 322 K, stable KIb → stable KIa at TC3 = 365 K, metastable KII ↔ overcooled K0 at TC2 = 376 K and stable KIa → stable K0 at TC1 = 379 K. The title comp...
