Polycyclic Aromatic Hydrocarbons (PAHs) have been implicated as
a large reservoir of reactive carbon in the interstellar medium
since the 1980s. PAHs have been widely attributed as the carriers
of the unidentified infrared bands where their...
Quantum computers employ quantum circuits to implement
algorithms. They are composed of quantum gates that act on near
neighbors according to some spatial geometry. They are particular
instances of quantum cellular automata (QCA), the set of...
Recently P. Etingof, E. Frenkel, and D. Kazhdan, following
earlier contributions by R. Langlands and J. Teschner, described an
“analytic” approach to the geometric Langlands correspondence, in
which the main ingredients are quantum states and...
One of the best laboratories to study strong-field gravity is
the inner 100s of kilometers around black holes and neutron stars
in binary systems with low-mass stars like our Sun. The X-ray light
curves of these systems show variability on...
Type IIB supergravity famously has a discrete duality group,
which is an exact symmetry of the full type IIB string theory. This
symmetry has potential quantum anomalies, which could render the
theory inconsistent. In this talk I will describe how...
We construct vacua of string theory in which all moduli are
stabilized and the magnitude of the cosmological constant is
exponentially small. The vacua are supersymmetric AdS_4
solutions in flux compactifications of type IIB string theory
on...
