Extended s-wave superconductivity in M-point twisted bilayer SnSe2
Lennart Klebl, Ammon Fischer, Salahudin V. SmailagiÄ +6
The authors model twisted bilayer SnSe2 with an M‑point moiré pattern and use functional renormalization group calculations to show that doping drives a transition from antiferroma…
Exotic Electronic Order in a Parabolic Kagome Semimetal
C. Alexander Baum, Jonas Issing, Sarbajit Mazumdar +4
We study an interacting kagome-lattice realization of a quadratic band-touching semimetal at 2/3 filling with onsite and nearest-neighbor repulsive interactions. Combining function…
Electron-Phonon Functional Renormalization Group of Fermi Liquid Instabilities
C. Alexander Baum, Matteo Dürrnagel, Ronny Thomale +1
We formulate a functional renormalization group (FRG) ansatz for correlated electron models that incorporates electronic interactions as well as electron-phonon coupling (EPC) stem…
Feasibility study of continuous electronic Pomeranchuk cooling with a flavor-degenerate Wigner crystal
Robin J. Dolleman, Ammon Fischer, Lennart Klebl +5
Achieving sub-millikelvin electron temperatures in nanoelectronic devices could unveil new transport phenomena, extend quantum coherence times, and enhance the precision of quantum…
Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
Dongjin Oh, Stefan Enzner, Lennart Klebl +12
The kagome superconductor family AV3Sb5 (A=Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various…
Altermagnons at the metal-insulator transition
Jonas Issing, Matteo Dürrnagel, Sarbajit Mazumdar +7
By means of slave-boson theory for the Hubbard model on the checkerboard lattice, we calculate dynamical altermagnetic spin susceptibilities from the metallic to the Mott-insulatin…
