Chiral magnetic effect at finite temperature in a field-theoretic approach

We investigate the existence (or lack thereof) of the chiral magnetic effect in the framework of finite temperature field theory, regularized via zeta functions. Expand abstract.

Gribov ambiguity

Additionally, the new form of the gluon propagator yields the violation of the reflection positivity which is considered as the important axiom of the Euclidean quantum field theory. Expand abstract.

Unstable states in a model of nonrelativistic quantum electrodynamics: rate of decay, regeneration by decay products, sojourn time and irreversibility

We consider a family of states in a model of nonrelativistic quantum electrodynamics, with positive Hamiltonian $H$. Expand abstract.

The Dynamic Ligand Field of a Molecular Qubit: Decoherence Through Spin–Phonon Coupling

Here we derive a general ligand field theory model to describe and quantify the nature of spin–phonon coupling terms in S = 1/2 transition metal complexes. Expand abstract.

Complexity for Charged Thermofield Double States

We study Nielsen's circuit complexity for a charged thermofield double state (cTFD) of free complex scalar quantum field theory in the presence of background electric field. Expand abstract.

Fusion and positivity in chiral conformal field theory

Conformal nets and vertex operator algebras are axiomatizations of two-dimensional chiral conformal field theories, both of which have had a significant impact on related mathematical areas of study. Expand abstract.

Sir Michael Atiyah, a Knight Mathematician A tribute to Michael Atiyah, an inspiration and a friend

Sir Michael Atiyah was considered as one of the world's foremost mathematicians, He is best known for his work in algebraic topology and the co-development of a branch of mathematics called topological K-theory together with the Atiyah-Singer index theorem for which he received Fields Medal (1966).
