Fermionic zero modes associated with doubly periodic SU (2) instantons of unit charge are considered. In cases where the action density exhibits two 'instanton cores' the zero mode peaks on one of four line-segments joining the two constituents. Which of the four possibilities is realised depends on the fermionic boundary conditions; doubly periodic, doubly anti-periodic or mixed. In this Lette...

OBJECTIVE Stroke is an important risk factor for dementia, but the exact mechanism involved in cognitive decline remains unclear. METHODS Patients were divided into 2 groups: poststroke dementia group (PSD) and poststroke nondementia group (PSND). Variables and neuroradiological hallmarks were compared between 2 groups at 3 months (114 subjects) and 1 year (105 subjects) after stroke. RESUL...

We define the problem “identity check”: Given a classical description of a quantum circuit, determine whether it is almost equivalent to the identity. Explicitly, the task is to decide whether the corresponding unitary is close to a complex multiple of the identity matrix with respect to the operator norm. We show that this problem is QMA-complete. A generalization of this problem is “equivalen...
