Spectral flow and localisation in AdS3 string theory
Journal of High Energy PhysicsWe study string theory in three-dimensional Anti-de Sitter spacetime in the path integral formalism. We derive expressions for generic spectrally-flowed near-boundary vertex operators in the Wakimoto representation, and relate their correlation functions

Lieb-Robinson bounds, the spectral flow, and stability of the spectral gap for lattice fermion systems. [PDF]
, 2017 We prove Lieb-Robinson bounds for a general class of lattice fermion systems. By making use of a suitable conditional expectation onto subalgebras of the CAR algebra, we can apply the Lieb-Robinson bounds much in the same way as for quantum spin systems.

Spectral modeling of rotating turbulent flows [PDF]
Physics of Fluids, 2010 A subgrid-scale spectral model of rotating turbulent flows is tested against direct numerical simulations (DNSs). The case of Taylor–Green forcing is considered, a configuration that mimics the flow between two counter-rotating disks as often used in the laboratory. Computations are performed for moderate rotation down to Rossby numbers of 0.03, as can

Observational constraint on the fourth derivative of the inflaton potential [PDF]
, 2002 We consider the flow-equations for the 3 slow-roll parameters n_S (scalar spectral index), r (tensor to scalar ratio), and dn_S/dlnk (running of the spectral index).

Spectral Flow and Global Topology of the Hofstadter Butterfly. [PDF]
Physical Review Letters, 2016 We study the relation between the global topology of the Hofstadter butterfly of a multiband insulator and the topological invariants of the underlying Hamiltonian.

Unbounded Fredholm Modules and Spectral Flow [PDF]
Canadian Journal of Mathematics, 1998 AbstractAn odd unbounded (respectively, p-summable) Fredholm module for a unital Banach *-algebra, A, is a pair (H,D) where A is represented on the Hilbert space, H, and D is an unbounded self-adjoint operator on H satisfying:(1) (1 + D2)-1 is compact (respectively, Trace_(1 + D2)-(p/2)_∞), and(2) ﹛a ∈ A | [D, a] is bounded﹜ is a dense *- subalgebra of

Spectral problem for water flow glazings [PDF]
Energy and Buildings, 2017 Water flow glazings are characterized by a water chamber which transports the absorbed solar energy in the glazing. A multilayer water flow glazing comprises glass layers, PVB (Polyvinyl Butyral) layers, coatings, air gaps, and a water layer. Heat absorption from solar radiation depends on the spectral properties of each layer.
