DOI: 10.1007/jhep01(2022)005
Abstract: Many CFT problems, e.g. ones with global symmetries, have correlation functions with a crossing antisymmetric sector. We show that such a crossing antisymmetric function can be expanded in terms of manifestly crossing antisymmetric objects, which… read more here.

DOI: 10.1016/j.ijsolstr.2019.12.007
Abstract: Abstract The discrete element method has been widely adopted to study the phononic dispersion relation of granular crystals, but its intrinsic limitations in the conventional particle contact model are often overlooked. In this study, we… read more here.

DOI: 10.1016/j.jastp.2017.04.004
Abstract: Abstract There is extensive evidence for ionospheric effects associated with earthquake-related atmospheric disturbances. Although the existence of earthquake precursors is controversial, one suggested method of detecting possible earthquake precursors and tsunamis is by observing possible… read more here.

DOI: 10.1038/ncomms15859
Abstract: To know the properties of a particle or a wave, one should measure how its energy changes with its momentum. The relation between them is called the dispersion relation, which encodes essential information of the… read more here.

DOI: 10.1088/1361-6587/aa76f1
Abstract: The analytical treatment of plasma kinetic linear instabilities in toroidal geometry is commonly tackled employing a power series expansion of the resonant part of the dispersion relation. This expansion is valid under the assumption that… read more here.

Abstract: We study the correspondence between models of a self-interacting canonical complex scalar field and P(X)-theories/shift-symmetric k-essence. Both describe the same background cosmological dynamics, provided that the amplitude of the complex scalar is frozen modulo the… read more here.
