Shell-model study of $^{28}$Si: coexistence of oblate, prolate and superdeformed shapes

Autor: Frycz, Dorian, Menéndez, Javier, Rios, Arnau, Bally, Benjamin, Rodríguez, Tomás R., Romero, Antonio M.

We study the shape coexistence in the nucleus $^{28}$Si with the nuclear shell model using numerical diagonalizations complemented with variational calculations based on the projected generator-coordinate method. The theoretical electric quadrupole m

The unexpected uses of a bowling pin: exploiting $^{20}$Ne isotopes for precision characterizations of collectivity in small systems

Autor: Giacalone, Giuliano, Bally, Benjamin, Nijs, Govert, Shen, Shihang, Duguet, Thomas, Ebran, Jean-Paul, Elhatisari, Serdar, Frosini, Mikael, Lähde, Timo A., Lee, Dean, Lu, Bing-Nan, Ma, Yuan-Zhuo, Meißner, Ulf-G., Noronha-Hostler, Jacquelyn, Plumberg, Christopher, Rodríguez, Tomás R., Roth, Robert, van der Schee, Wilke, Somà, Vittorio

Whether or not femto-scale droplets of quark-gluon plasma (QGP) are formed in so-called small systems at high-energy colliders is a pressing question in the phenomenology of the strong interaction. For proton-proton or proton-nucleus collisions the a

On compactness of products of Toeplitz operators

Autor: Le, Trieu, Rodriguez, Tomas Miguel, Sahutoglu, Sonmez

We study compactness of product of Toeplitz operators with symbols continuous on the closure of the polydisc in terms of behavior of the symbols on the boundary. For certain classes of symbols $f$ and $g$, we show that $T_fT_g$ is compact if and only

Symmetry-projected variational calculations with the numerical suite TAURUS II. Configuration mixing of symmetry-projected reference states

Autor: Bally, Benjamin, Rodríguez, Tomás R.

Publikováno v: Eur. Phys. J. A (2024) 60: 62

We present the numerical codes TAURUS_pav and TAURUS_mix that, combined, perform the configuration mixing of symmetry-projected real general Bogoliubov quasiparticle states represented in a spherical harmonic oscillator basis. The model space conside

Compactness of Toeplitz operators with continuous symbols on pseudoconvex domains in $\mathbb{C}^n$

Autor: Rodriguez, Tomas Miguel, Sahutoglu, Sonmez

Publikováno v: Proc. Amer. Math. Soc. Ser. B 11 (2024), 406--421

Let $\Omega$ be a bounded pseudoconvex domain in $\mathbb{C}^n$ with Lipschitz boundary and $\phi$ be a continuous function on $\overline{\Omega}$. We show that the Toeplitz operator $T_{\phi}$ with symbol $\phi$ is compact on the weighted Bergman sp

Optimization of the number of intrinsic states included in the discrete Generator Coordinate Method

Autor: Martínez-Larraz, Jaime, Rodríguez, Tomás R.

We present a mechanism to efficiently pre-select the number of intrinsic many-body states that are used to define the many-body wave functions within the discrete Generator Coordinate Method (GCM). This procedure, based on the proper definition of a
