Modified Mukhanov-Sasaki equation and primordial perturbations in -deformed non-commutative space-time
Yang Lei, Vishnu Rajagopal, Puxun Wu
We study the inflationary primordial perturbations in -Minkowski non-commutative space-time, a Lie-algebraic type deformation of canonical space-time motivated by quantum gravi…
Gauge dependence of scalar-induced gravitational waves from isocurvature perturbations: Analytical results
Arshad Ali, Yang Lei, Mudassar Sabir
We analytically study the gauge dependence of scalar-induced gravitational waves (SIGWs) sourced by primordial isocurvature perturbations during radiation domination (RD), working…
Preparation and measurement of an Ar source for liquid xenon detector calibration
Xu-Nan Guo, Chang Cai, Fei Gao +8
We present the preparation and measurement of the radioactive isotope , which was produced using thermal neutrons from a reactor, as a calibration source for liquid xe…
Notes on suu Chern-Simons theory and Torsional Newton-Cartan gravity
Yang Lei, Dong Zhang
In this study, we investigate three-dimensional torsional Newton-Cartan (TNC) gravity by gauging the suu algebra and construct its action using the Chern-Simons t…
Conformal Mapping of Non-Lorentzian Geometries in SU(1,2) Conformal Field Theory
Stefano Baiguera, Troels Harmark, Yang Lei +1
We realize an explicit conformal mapping between the state and operator pictures in a class of (2+1)-dimensional non-Lorentzian field theories with SU(1,2)U(1) conformal sy…
