Gravitino Problem in Inflation Driven by Inflaton-Polonyi K\"ahler Coupling
, 2017 We discuss the cosmological gravitino problem in inflation models in which the inflaton potential is constructed from K\"ahler potential rather than superpotential: a representative model is $\overline{\text{D}3}$-induced geometric inflation.

IET Smart Grid, Volume 7, Issue 4, Page 386-399, August 2024.The authors propose the total supply capability (TSC) of the low‐voltage flexible distribution network (LVFDN) for the first time. The influence mechanism for low‐voltage flexible interconnection on TSC is quantitatively analysed with a case study. Furthermore, suggestions for the planning and operation of LVFDN are given.

Neutrino-electron scattering in noncommutative space
, 2010 Neutral particles can couple with the $U(1)$ gauge field in the adjoint representation at the tree level if the space-time coordinates are noncommutative (NC). Considering neutrino-photon coupling in the NC QED framework, we obtain the differential cross

Asymmetric all‐pay auctions with spillovers
Theoretical Economics, Volume 19, Issue 1, Page 169-206, January 2024.When opposing parties compete for a prize, the sunk effort players exert during the conflict can affect the value of the winner's reward. These spillovers can have substantial influence on the equilibrium behavior of participants in applications such as lobbying, warfare, labor tournaments, marketing, and R&D races.

Models of f(R) Cosmic Acceleration that Evade Solar-System Tests
, 2007 We study a class of metric-variation f(R) models that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the parameter space.

Theoretical Economics, Volume 19, Issue 1, Page 365-405, January 2024.We study a model in which two players with opposing interests try to alter a status quo through instability‐generating actions. We show that instability can be used to secure longer‐term durable changes, even if it is costly to generate and does not generate short‐term gains.

Theoretical Economics, Volume 19, Issue 1, Page 207-244, January 2024.I study sequential contests where the efforts of earlier players may be disclosed to later players by nature or by design. The model has many applications, including rent seeking, R&D, oligopoly, public goods provision, and tragedy of the commons. I show that information about other players' efforts increases the total effort. Thus, the total effort is

Ethnicity and Conflict: An Empirical Study
, 2012 We examine empirically the impact of ethnic divisions on conflict, by using a specification based on Esteban and Ray (2011). That theory links conflict intensity to three indices of ethnic distribution: polarization, fractionalization, and the Gini ...

Chiral Anomaly Beyond Lorentz Invariance [PDF]
, 2007 The chiral anomaly in the context of an extended standard model with minimal Lorentz invariance violation is studied. Taking into account bounds from measurements of the speed of light, we argue that the chiral anomaly and its consequences are general ...
