Baryon preclustering at the freeze-out of heavy-ion collisions and light-nuclei production

E Shuryak, JM Torres-Rincon - Physical Review C, 2020 - APS
Following the idea of nucleon clustering and light-nuclei production in relativistic heavy-ion
collisions close to the QCD critical-end point, we address the quantum effects affecting the …

Light-nuclei production and search for the QCD critical point

E Shuryak, JM Torres-Rincon - The European Physical Journal A, 2020 - Springer
We discuss the potential of light-nuclei measurements in heavy-ion collisions at intermediate
energies for the search of the hypothetical QCD critical end-point. A previous proposal …

[图书][B] Quantum Anharmonic Oscillator

A Turbiner, JCDV Rosales - 2023 - books.google.com
Quartic anharmonic oscillator with potential V (x)= x²+ g²x⁴ was the first non-exactly-
solvable problem tackled by the newly-written Schrödinger equation in 1926. Since that time …

From quartic anharmonic oscillator to double well potential

AV Turbiner, JC del Valle - arXiv preprint arXiv:2111.01546, 2021 - arxiv.org
It is already known that the quantum quartic single-well anharmonic oscillator $ V_ {ao}(x)=
x^ 2+ g^ 2 x^ 4$ and double-well anharmonic oscillator $ V_ {dw}(x)= x^ 2 (1-gx)^ 2$ are …

Transseries for the ground state density and generalized Bloch equation: Double-well potential case

E Shuryak, AV Turbiner - Physical Review D, 2018 - APS
Based on the generalized Bloch equation, the transseries expansion for the phase

Fluctuations in quantum mechanics and field theories from a new version of semiclassical theory. II.

MA Escobar-Ruiz, E Shuryak, AV Turbiner - Physical Review D, 2017 - APS
This is the second paper on the semiclassical approach based on the density matrix given
by the Euclidean time path integral with fixed coinciding end points. The classical path …

A simple locally accurate uniform approximation for the nodeless wave function is
constructed for a neutral system of two Coulomb charges of different masses (− q, m 1) and …

[HTML][HTML] Two-loop corrections to false vacuum decay in scalar field theory

MA Bezuglov, AI Onishchenko - Physics Letters B, 2019 - Elsevier
We consider radiative corrections to false vacuum decay in a four-dimensional scalar field
