Entanglement Entropy Growth in Disordered Spin Chains with Tunable Range Interactions
Youcef Mohdeb, Javad Vahedi, Ravindra N. Bhatt +2
The non-equilibrium dynamics of disordered many-body quantum systems after a global quantum quench unveils important insights about the competition between interactions and disorde…
Edge and corner superconductivity in a 2D topological model
Ying Wang, Gautam Rai, Stephan Haas +1
We consider a two-dimensional generalization of the Su-Schrieffer-Heeger model which is known to possess a non-trivial topological band structure. For this model, which is characte…
Real-space BCS-BEC crossover in FeSe monolayer
Haicheng Lin, Wantong Huang, Gautam Rai +7
The quantum many body states in the BCS-BEC crossover regime are of long-lasting interest. Here we report direct spectroscopic evidence of BCS-BEC crossover in real-space in a FeSe…
Plasmons in Z2 Topological Insulators
Yuling Guan, Stephan Haas, Henning Schlomer +1
We study plasmonic excitations in the Kane-Mele model, a two-dimensional Z2 topological insulator on the honeycomb lattice, using the random phase approximation (RPA). In the topol…
Parity effects and universal terms of O(1) in the entanglement near a boundary
Henning Schlömer, Chunyu Tan, Stephan Haas +1
In the presence of boundaries, the entanglement entropy in lattice models is known to exhibit oscillations with the (parity of the) length of the subsystem, which however decay to…
Collision Dynamics of Bose-Einstein Condensates
Aaron Wirthwein, Stephan Haas, Sheng-wey Chiow
We study the collision dynamics of two Bose-Einstein condensates with their dynamical wave functions modeled by a set of coupled, time-dependent Gross-Pitaevskii equations. Beginni…
