Dynamics of spin spirals in a voltage biased 1D conductor
Xiaohu Han, Pedro Ribeiro, Stefano Chesi
We analyze the fate of spiral order in a one-dimensional system of localized magnetic moments coupled to itinerant electrons under a voltage bias. Within an adiabatic approximation…
Recent advances in hole-spin qubits
Yinan Fang, Pericles Philippopoulos, Dimitrie Culcer +2
In recent years, hole-spin qubits based on semiconductor quantum dots have advanced at a rapid pace. We first review the main potential advantages of these hole-spin qubits with re…
Probing Kondo spin fluctuations with scanning tunneling microscopy and electron spin resonance
Yinan Fang, Stefano Chesi, Mahn-Soo Choi
We theoretically analyze a state-of-the-art experimental method based on a combination of electron spin resonance and scanning tunneling microscopy (ESR-STM), to directly probe the…
Nonequilibrium phases and phase transitions of the XY-model
Tharnier O. Puel, Stefano Chesi, Stefan Kirchner +1
We obtain the steady-state phase diagram of a transverse field XY spin chain coupled at its ends to magnetic reservoirs held at different magnetic potentials. In the long-time limi…
Pseudospin-electric coupling for holes beyond the envelope-function approximation
Pericles Philippopoulos, Stefano Chesi, Dimitrie Culcer +1
In the envelope-function approximation, interband transitions produced by electric fields are neglected. However, electric fields may lead to a spatially local (-independent) co…
Phase diagram of the interacting persistent spin-helix state
Hong Liu, Weizhe Edward Liu, Stefano Chesi +2
We study the phase diagram of the interacting two-dimensional electron gas (2DEG) with equal Rashba and Dresselhaus spin-orbit coupling, which for weak coupling gives rise to the w…
