Renormalization in open quantum field theory. Part I. Scalar field theory

Journal of High Energy Physics, 2017
While the notion of open quantum systems is itself old, most of the existing studies deal with quantum mechanical systems rather than quantum field theories.

Light neutralino dark matter in U(1)XSSM

Nuclear Physics B, 2021
The U(1)X extension of the minimal supersymmetric standard model (MSSM) is called as U(1)XSSM with the local gauge group SU(3)C×SU(2)L×U(1)Y×U(1)X. U(1)XSSM has three singlet Higgs superfields beyond MSSM.

Linear Superposition as a Core Theorem of Quantum Empiricism

Universe, 2022
Clarifying the nature of the quantum state |Ψ⟩ is at the root of the problems with insight into counter-intuitive quantum postulates. We provide a direct—and math-axiom free—empirical derivation of this object as an element of a vector space ...

Incorporating element doping and quantum dot embedding effects to enhance the thermoelectric properties of higher manganese silicides

Journal of Materiomics, 2021
Element doping and nano-inclusion embedding are effective approaches to enhance the electrical conductivities and decrease the lattice thermal conductivities of thermoelectric (TE) materials, respectively.

Anyon condensation: coherent states, symmetry enriched topological phases, Goldstone theorem, and dynamical rearrangement of symmetry

Journal of High Energy Physics, 2022
Although the mathematics of anyon condensation in topological phases has been studied intensively in recent years, a proof of its physical existence is tantamount to constructing an effective Hamiltonian theory. In this paper, we concretely establish the

Electric dipole moments of neutron and heavy quarks c, t in CP violating U(1)XSSM

Nuclear Physics B, 2022
We study and analyze the electric dipole moments (EDMs) of neutron and heavy quarks c, t in a CP-violating (CPV) supersymmetric U(1) extension of the standard model called U(1)XSSM, whose local gauge group is U(1)X×SU(3)C×SU(2)L×U(1)Y.

Unfree gauge symmetry in the BV formalism

European Physical Journal C: Particles and Fields, 2019
The BV formalism is proposed for the theories where the gauge symmetry parameters are unfree, being constrained by differential equations.

A note on unfree gauge symmetry

Nuclear Physics B, 2019
We study the general structure of field theories with the unfree gauge symmetry where the gauge parameters are restricted by differential equations.

Extend the Levin-Wen model to two-dimensional topological orders with gapped boundary junctions

Journal of High Energy Physics, 2022
A realistic material may possess defects, which often bring the material new properties that have practical applications. The boundary defects of a two-dimensional topologically ordered system are thought of as an alternative way of realizing topological

Enhancing thermoelectric performance of n-type AgBi3S5 through synergistically optimizing the effective mass and carrier mobility

Journal of Materiomics, 2023
AgBi3S5 is a new n-type thermoelectric material that is environmentally friendly and composed of elements of earth-abundant, non-toxic and high performance-cost ratio.
