Quantized classical response from spectral winding topology
Linhu Li, Sen Mu, Ching Hua Lee +1
Topologically quantized response is one of the focal points of contemporary condensed matter physics. While it directly results in quantized response coefficients in quantum system…
Topological and dynamical features of periodically driven spin ladders
Raditya Weda Bomantara, Sen Mu, Jiangbin Gong
Studies of periodically driven one-dimensional many-body systems have advanced our understanding of complex systems and stimulated promising developments in quantum simulation. It…
Critical non-Hermitian Skin Effect
Linhu Li, Ching Hua Lee, Sen Mu +1
This work uncovers a new class of criticality where eigenenergies and eigenstates of non-Hermitian lattice systems jump discontinuously across a critical point in the thermodynamic…
Emergent Fermi surface in a many-body non-Hermitian Fermionic chain
Sen Mu, Ching Hua Lee, Linhu Li +1
Quantum degeneracy pressure (QDP) underscores the stability of matter and is arguably the most ubiquitous many-body effect. The associated Fermi surface (FS) has broad implications…
Revealing many-body effects on interband coherence through adiabatic charge pumping
Sen Mu, Da-Jian Zhang, Longwen Zhou +1
The adiabatic charge pumping of a non-equilibrium state of spinless fermions in a one-dimensional lattice is investigated, with an emphasis placed on its usefulness in revealing ma…
