Quantum and Thermal Fluctuations of Cherenkov Radiation from HQET
Joshua Lin, Bruno Scheihing-Hitschfeld
Charged particles travelling faster than the speed of light in the medium in which they propagate emit Cherenkov radiation. The formula for the spectrum of this radiation as a func…
Lattice field theory for superconducting circuits
Joshua Lin, Max Hays, Stephen Sorokanich +3
Large superconducting quantum circuits have a number of important applications in quantum computing. Accurately predicting the performance of these devices from first principles is…
Dirac Traces and the Tutte Polynomial
Joshua Lin
Perturbative calculations involving fermion loops in quantum field theories require tracing over Dirac matrices. A simple way to regulate the divergences that generically appear in…
Real-time Dynamics of the Schwinger Model as an Open Quantum System with Neural Density Operators
Joshua Lin, Di Luo, Xiaojun Yao +1
Ab-initio simulations of multiple heavy quarks propagating in a Quark-Gluon Plasma are computationally difficult to perform due to the large dimension of the space of density matri…
Position-space renormalization schemes for four-quark operators in HQET
Joshua Lin, William Detmold, Stefan Meinel
X-space schemes are gauge-invariant, regulator-independent renormalization schemes that are defined by requiring position-space correlation functions of gauge invariant operators t…
