Effective Polaron Dynamics of an Impurity Particle Interacting with a Fermi Gas
Autor: Hoang, Duc Viet, Pickl, Peter
We study the quantum dynamics of a homogeneous ideal Fermi gas coupled to an impurity particle on a three-dimensional box with periodic boundary condition. For large Fermi momentum $k_\text{F}$, we prove that the effective dynamics is generated by a

Intelligence Education made in Europe
Autor: Berger, Lars, Borghoff, Uwe M., Conrad, Gerhard, Pickl, Stefan
Global conflicts and trouble spots have thrown the world into turmoil. Intelligence services have never been as necessary as they are today when it comes to providing political decision-makers with concrete, accurate, and up-to-date decision-making k

Autor: Valerie Hartmann, Simon Udo Engelmann, Christoph Pickl, Maximilian Haas, Sebastian Kälble, Christopher Goßler, Christoph Eckl, Aybike Hofmann, Renate Pichler, Maximilian Burger, Roman Mayr
Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-10 (2024)
Abstract Sarcopenia, defined as age-associated loss of skeletal muscle function and muscle mass, is a negative prognostic marker for survival in several tumor entities. However, data evaluating the impact of sarcopenia and fat distribution on penile

Exponential decay of the number of excitations in the weakly interacting Bose gas
Autor: Mitrouskas, David, Pickl, Peter
We consider $N$ trapped bosons in the mean-field limit with coupling constant $\lambda_N=1 / (N-1)$. The ground state of such systems exhibits Bose--Einstein condensation. We prove that the probability of finding $\ell$ particles outside the condensa

Microscopic derivation of Vlasov equation with compactly supported pair potentials
Autor: Feistl, Manuela, Pickl, Peter
We present a probabilistic proof of the mean-field limit and propagation of chaos of a N-particle system in three dimensions with compactly supported pair potentials of the form $N^{3\beta-1} \phi(N^{\beta}x)$ for $\beta\in\left[0,\frac{1}{7}\right)$
