Universality of internal correlations of strongly interacting p-wave fermions in one-dimensional geometry
Przemysław Kościk, Tomasz Sowiński
We consider the many-body ground state of polarized fermions interacting via zero-range -wave forces in a one-dimensional geometry. We rigorously prove that in the li…
On the Exponential Decay of Strongly Interacting Cold Atoms from a Double-Well Potential
Przemysław Kościk
In this article, we study an exponential decay for the gas of bosons with strong repulsive delta interactions from a double-well potential. We consider an exactly solvable model co…
A high-resolution pixel silicon Vertex Detector for open charm measurements with the \NASixtyOne spectrometer at the CERN SPS
A. Aduszkiewicz, M. Bajda, M. Baszczyk +24
The study of open charm meson production provides an efficient tool for the investigation of the properties of hot and dense matter formed in nucleus-nucleus collisions. The interp…
Pair-correlation ansatz for the ground state of interacting bosons in an arbitrary one-dimensional potential
Przemysław Kościk, Arkadiusz Kuroś, Adam Pieprzycki +1
We derive and describe a very accurate variational scheme for the ground state of the system of a few ultra-cold bosons confined in one-dimensional traps of arbitrary shapes. It is…
Variational ansatz for -wave fermions confined in a one-dimensional harmonic trap
Przemysław Kościk, Tomasz Sowiński
We propose a very accurate and efficient variational scheme for the ground state of the system of -wave attractively interacting fermions confined in a one-dimensional harmonic…
Decay properties of unstable Tonks-Girardeau gases from a split trap
Przemysław Kościk
We study the decay properties of Tonks-Girardeau gases escaping from a double-well potential. Initially, the gases are constrained between two infinite barriers with an on-cent…
Capturing non-exponential dynamics in the presence of two decay channels
Francesco Giacosa, Przemysław Kościk, Tomasz Sowiński
The most unstable quantum states and elementary particles possess more than a single decay channel. At the same time, it is well known that typically the decay law is not simply ex…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
