Gravitational Core of Double Field Theory: Lecture Notes
Jeong-Hyuck Park
Double Field Theory (DFT) has emerged as a comprehensive framework for gravity, presenting a testable and robust alternative to General Relativity (GR), rooted in the $\mathbf{O}(D…
Late-time Cosmology without Dark Sector but with Closed String Massless Sector
Hocheol Lee, Jeong-Hyuck Park, Liliana Velasco-Sevilla +1
We explore the possibility of solving the dark energy and the coincidence problems by postulating the massless sector of closed strings. This sector constitutes the gravitational m…
Distinguishable Cash, Bosonic Bitcoin, and Fermionic Non-fungible Token
Zae Young Kim, Jeong-Hyuck Park
Modern technology has brought novel types of wealth. In contrast to hard cashes, digital currencies do not have a physical form. They exist in electronic forms only. Yet, it has no…
Lecture note on Clifford algebra
Jeong-Hyuck Park
This lecture note surveys the gamma matrices in general dimensions with arbitrary signatures, the study of which is essential to understand the supersymmetry in the corresponding s…
Janus van der Waals equations for real molecules with two-sided phase transitions
Jihwan Kim, Do-Hyun Kim, Jeong-Hyuck Park
We obtain families of generalised van der Waals equations characterised by an even number and a continuous free parameter which is tunable for a critical compressibility…
Post-Newtonian Feasibility of the Closed String Massless Sector
Kang-Sin Choi, Jeong-Hyuck Park
We perform post Newtonian analysis of Double Field Theory as a test of string theory in gravitational sector against observations. We identify the Eddington--Robertson--Schiff para…
