Summary 
The energy momentum tensor (EMT) is one of the most fundamental observables in physics. Recently, a novel method to define EMT on the basis of the gradientflow formalism has been proposed. It turned out that the EMT operator can be constructed even on the lattice with the method, which enables nonperturbative computations. This approach has been successfully applied to the analyses on thermodynamic quantities. This book presents the study on spatial EMT distributions around static charges via the gradient flow in lattice simulations based on SU(3) YangMills theory. Static charges are employed as probes to explore complex quantum systems, and EMT then characterizes the response of vacuum as well as hot medium under the existence of the charges, which significantly provides profound and novel insights into the nonperturbative phenomena, such as the confinement of quarks. In addition, the book treats the study on the EMT distribution around a magnetic vortex in the AbelianHiggs model, which is compared with the lattice result. These achievements open up various future studies for revealing nontrivial aspects of the strong interaction. The book also includes wellorganized reviews on general properties of EMT, lattice gauge theory and the gradientflow formalism with its application to the definition of EMT. They are useful for students and young researchers as a brief introduction to this field
