We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

We review the properties of BPS, or supersymmetric, magnetic monopoles, with an
emphasis on their low-energy dynamics and their classical and quantum bound states. After …

We investigate the correspondence between existence/stability of BPS states in type-II string
theory compactified on a Calabi-Yau manifold and BPS solutions of four-dimensional N= 2 …

We present the detailed derivation of the charge-1 periodic instantons—or calorons—with
non-trivial holonomy for SU (2). We use a suitable combination of the Nahm transformation …

Two pictures of BPS bound states in Calabi-Yau compactifications of type-II string theory
exist, one as a set of particles at equilibrium separations from each other, the other as a …

These lectures cover aspects of solitons with focus on applications to the quantum dynamics
of supersymmetric gauge theories and string theory. The lectures consist of four sections …

We present a simple result for the action density of the SU (n) charge one periodic
instantons–or calorons–with arbitrary non-trivial Polyakov loop P∞ at spatial infinity. It is …

A bstract We compute the Witten index of one-dimensional gauged linear sigma models with
at least\(\mathcal {N}\)= 2 supersymmetry. In the phase where the gauge group is broken to …

We initiate the classification of unitary superconformal defects in unitary superconformal field
theories (SCFT) of diverse spacetime dimensions $3\leq d\leq 6$. Our method explores …

A bstract We show that the BPS spectrum of pure SU (3) four-dimensional super Yang-Mills
with\(\mathcal {N}\)= 2 supersymmetry exhibits a surprising phenomenon: there are regions …
