Dual D-Brane Actions in Nonrelativistic String Theory
Stephen Ebert, Hao-Yu Sun, Ziqi Yan
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory. This theory is a self-cont…
KLT Factorization of Nonrelativistic String Amplitudes
Ziqi Yan, Matthew Yu
We continue our study of the Kawai-Lewellen-Tye (KLT) factorization of winding string amplitudes. In a toroidal compactification, amplitudes for winding closed string states factor…
Zero Magnetic Field Plateau Phase Transition in Higher Chern Number Quantum Anomalous Hall Insulators
Yi-Fan Zhao, Ruoxi Zhang, Ling-Jie Zhou +5
The plateau-to-plateau transition in quantum Hall effect under high magnetic fields is a celebrated quantum phase transition between two topological states through either sweeping…
Torsional Deformation of Nonrelativistic String Theory
Ziqi Yan
Nonrelativistic string theory is a self-contained corner of string theory, with its string spectrum enjoying a Galilean-invariant dispersion relation. This theory is unitary and ul…
Strings in Bimetric Spacetimes
Ziqi Yan
We put forward a two-dimensional nonlinear sigma model that couples (bosonic) matter fields to topological Horava gravity on a nonrelativistic worldsheet. In the target space, this…
KLT Factorization of Winding String Amplitudes
Jaume Gomis, Ziqi Yan, Matthew Yu
We uncover a Kawai-Lewellen-Tye (KLT)-type factorization of closed string amplitudes into open string amplitudes for closed string states carrying winding and momentum in toroidal…
New Heat Kernel Method in Lifshitz Theories
Kevin T. Grosvenor, Charles Melby-Thompson, Ziqi Yan
We develop a new heat kernel method that is suited for a systematic study of the renormalization group flow in Horava gravity (and in Lifshitz field theories in general). This meth…
