Melting temperature shifts from quantum fluctuations in generalized Wigner crystals
Aman Kumar, Sogoud Sherif, Veit Elser +1
It is generally believed that quantum fluctuations collaborate with thermal fluctuations, effectively reducing transition temperatures (e.g. for melting of charge order). We show t…

The recently discovered dipole-octupole pyrochlore magnet CeHfO is a promising three-dimensional quantum spin liquid candidate which shows no signs of ordering at low t…
Emergent strong zero mode through local Floquet engineering
Bhaskar Mukherjee, Ronald Melendrez, Marcin Szyniszewski +2
Periodically driven quantum systems host exotic phenomena which often do not have any analog in undriven systems. Floquet prethermalization and dynamical freezing of certain observ…
Locally controlled arrested thermalization
Ken K. W. Ma, Hitesh J. Changlani
The long-time dynamics of quantum systems, typically, but not always, results in a thermal steady state. The microscopic processes that lead to or circumvent this fate are of inter…
