We revisit the DD* interactions in chiral effective field theory up to the third order for the first
time. We deal with the pion-exchanged interactions via local momentum-space …

We use the diffusion Monte Carlo (DMC) method to calculate the doubly heavy tetraquark T
cc system in two kinds of constituent quark models, the pure constituent quark model …

Higher-order exceptional points (EPs), resulting from non-Hermitian degeneracies, have
shown greater advantages in sensitive enhancement than second-order EPs (EP2s) …

We relate the interactions of the D¯(*) K* and D (*) K* systems to those of D (*) D (*) and D
(*) D¯(*) respectively, considering the residual strong interactions at the near-threshold …

Higher-order exceptional points (EPs) in non-Hermitian systems have attracted great interest
due to their advantages in sensitive enhancement and distinct topological features …

We calculate the energy spectrum of the S-wave doubly heavy tetraquark systems, including
the QQ (′) q¯ q¯, QQ (′) s¯ q¯, and QQ (′) s¯ s¯(Q (′)= b, c and q= u, d) systems within …

In this work, we make a study of the T cc+ state observed by the LHCb collaboration in 2021.
In obtaining the effective potentials using the one-boson-exchange potential model we use …

In the past years, many efforts have been made to study various noteworthy phenomena in
both parity-time (PT) and anti-parity-time (APT) symmetric systems. However, entanglement …

The interaction between light and mechanical vibrations in a cavity is often exploited to
produce higher-order sidebands (HOSs) or combs, which are used in optical communication …

Noether's theorem is one of the fundamental laws in physics, relating the symmetry of a
physical system to its constant of motion and conservation law. On the other hand, there …
