We propose and solve a minimal model of dynamic passage through a quantum second order phase transition in the presence of weak symmetry breaking interactions and no dissipation. The evolution eventually leads to a highly asymmetric state, no matter

Advances in ultracold chemistry have led to the possibility of a coherent transformation between ultracold atoms and molecules including between completely bosonic condensates. Such transformations are enabled by the magneto-association of atoms at a

The passage through a critical point of a many-body quantum system leads to abundant nonadiabatic excitations. Here, we explore a regime, in which the critical point is not crossed although the system is passing slowly very close to it. We show that

Background. Cardiovascular diseases remain a pressing issue associated with great economic burden and loss of earning capacity. Among them, thoracic aortic aneurysms pose a serious threat as they commonly develop asymptomatically. Patients with aneur

BACKGROUND: Mitral valve calcinosis is a chronic degenerative process in the fibrous structures of the mitral valve. Advanced stages increase the risk of endocarditis and cardiac rhythm disturbances and contribute to cardiovascular mortality. The cau

The high temperature limit of interacting spins is usually not associated with ordering or critical phenomena. Nevertheless, spontaneous fluctuations of a local spin polarization at equilibrium have nontrivial dynamics even in this limit. Here, we de

We investigate magnetic fluctuations of a mesoscopic critical region at the interface induced by smooth time-independent spacial changes of a control parameter across its critical value. Near the spatial critical point, the order parameter fluctuatio

The Number Partitioning Problem (NPP) is one of the NP-complete computational problems. Its definite exact solution generally requires a check of all $N$ solution candidates, which is exponentially large. Here we describe a path to the fast solution
